Bushmaster Firearms International has been making world-class rifles ever since 1973, and most famously, their AR-15 variants. The American-based company, currently owned by the Freedom Group, is the leading distributor of AR-15 variants in the U.S. The reason I refer to it as a variant is because, technically, Colt owns the trademark and all other brands simply replicate it. Colt bought the rights to the gun from ArmaLite in the late 1950’s, which is the source of the “AR” (ArmaLite Rifle) distinction. Nevertheless, Bushmaster’s AR-15 models are considered top of the line and are used by militaries and law enforcement agencies around the world. The semi-automatic M4 carbines (available as A2 or A3 models) are arguably their best ARs and are just one of many great weapons in their XM-15 line. A lot has changed for the AR-15; it is significantly heavier, more widespread, and has gained notoriety for its use in crimes across the globe. The original model was designed solely for police and military use but has since been adapted for civilians.

The first model is now a major collector’s item because of several favorite discontinued features. Since the 1994 federal assault weapons ban expired in 2004, sales for semi-automatic firearms, especially the AR-15s, have skyrocketed. Hunters, competitive shooters, and police have consistently applauded this weapon, and reasonably so. The AR-15 has been celebrated for decades not just for being extremely accurate and reliable, but also for its customizing capabilities. Because of its minimal recoil and user-friendliness this semi-auto is suitable for novices and experts alike. Rest assured that all of your M4-required reading needs are covered here in our Bushmaster M4 Type Carbine (AR-15) Review.

Bushmaster M4-Type Carbine (AR-15) Specs

Bushmaster proudly asserts that all of their M4s are built to meet or exceed Mil Spec (U.S. military standards).  With the M4’s impressive specs and top-notch American engineering, it’s no wonder why it is one of the most widely circulated AR-15s in the world. Bushmaster is clearly dedicated to producing top-shelf firearms and their constant spec upgrades and innovations attest to that.

Bushmaster M4 Build

Bushmaster Firearm’s M4 Carbine (XM-15 line) was engineered according to the United States Military Standard and modified for civilian use resulting in a striking and universal rifle. There are countless MSR (modern sporting rifle) parts out there and it’s good to know that every fine detail and accessory for your M4 Carbine can be customized to your liking. The M4 was constructed to be extremely accurate and durable, and the Teflon-coated 7075 T6 anodized receivers and chrome-lined barrel (with 1×7” twist) ensure just that. To ensure speed and efficiency, the M4 is built with the classic M16 bolt carrier for smoother cycling, and M4 feed ramps for better feeding. Remarkably, Bushmaster designed this gun’s rear with outstanding capabilities.

First and foremost is their Mil Spec 6-position stock, which easily adjusts to any shooter’s precise preferences. For added durability, they added the Mil Spec receiver extension (buffer tube) and developed a staked castle nut to stabilize it. The M4 comes with forged upper and lower receivers, but if you are a stickler for carry handles, remember the A2’s is fixed and the A3’s is detachable (enabling access to a Picatinny rail). In my experience, one factor that is often overlooked is magazine availability, and our gun here can accept all AR-15/M16 type STANAG/NATO mags. Depending on your preference, two different flash suppressors are available.

The standard models feature the fixed flash suppressor and the Patrolman carbines are equipped with the highly popular removable “bird cage” suppressor. Another plus is that all critical steel components of the firearm are coated with a Mil Spec. manganese phosphate to protect against corrosion. This gun is built to last!

Bushmaster M4 Shooting & Performance

As noted previously, this gun was engineered to shoot accurately and effortlessly for years. Nearly every component of the M4 was designed to make it more user-friendly and precise. M4’s are famous for their nominal recoil, and because of its strong grip and 6-position stock, any shooter can find a comfortable arrangement. With the introduction of the free floating hand guards in the 90s, the AR-15 variant’s accuracy skyrocketed. Furthermore, the cycling and feeding of this gun are extremely reliable, which makes shooting it easy and fun. Because Bushmaster has made personalization basically effortless, shooters of all skill-sets, experiences, purposes, and preferences, can perfectly mix and match their weapon.

The sights on the M4 are pretty standard, but see below for a more in-depth analysis. It’s my firm belief that the numbers speak for themselves, and Bushmaster’s AR-15’s are among the world top-selling in the world for good reason.

Bushmaster M4 Magazines & Sights

The M4 feed ramps and bolt carriers are the harmonious partners for the already impressive magazine system of the Bushmaster AR-15’s. Their feeding system works with the various universal STANAG magazines, which makes several configurations and capacities are available. Although originally prone to malfunction, the STANAGs have been heavily modified with high-grade steel bodies, rust-resistant chrome-silicon springs, and anti-tilt followers, to be highly resilient and reliable.

To say that the M4 comes equipped with basic adjustable front and rear iron sights would be a gross underestimation. Many people prefer to remove the carry handle and mount a Picatinny rail to increase their options. Some rear sight carbine systems offer both wind and elevation adjustments, which obviously make shooting in harsher conditions much easier. Depending on each shooter’s preference and purpose, a wide variety of scopes, holographic sights, red dots, and night vision equipment are mountable on the upper receiver’s rail.

M4 Safety & Assembly

The safety features of Bushmaster’s M4 model AR-15 variants are standard, which makes firing in “combat” situations quick and easy. Although gun safety is pretty universal, Bushmaster has a list of fundamental safety precautions on their website, which I recommend reading.

To disassemble your Bushmaster M4 AR-15 first remove the two pins in the lower receiver (you may need a small prodding tool for this) and detach the upper and lower receivers. Next, take your upper receiver and remove the charging handle and bolt carrier. For the next step you will need your multi-tool to remove the firing pin retaining pin and then drop your firing pin out. Be careful not to lose these – they are very small. The final piece of the upper receiver is the bolt, and all you have to do is push in and twist the knob and it should come right out. Now onto the lower half; first pull out the buffer tube, buffer, and recoil spring. It is as simple as that.

This gun is as easy to put back together as it is to disassemble. It is very important that at each stage of the process to make sure to clean each piece and compartment. Failure to keep your gun clean can negatively affect your gun’s efficiency and life-span. One of the places that people neglect to clean is the area where the firing pin rests. This failure has unfortunately caused too many AR-15s to become less reliable – clean it well!

Bushmaster M4 Prices

With several options like A2, A3, or Patrolman series, prices for the Bushmaster AR-15 variant can vary between $650 and $1,000. It’s not uncommon to buy one of these rifles used, but make sure you buy from a highly reputable source. The last thing you want to do is find a great deal and then find out at the range why it was so cheap. For such a high-quality firearm that will last for years, the price is a reasonable investment for any serious shooter.

Bushmaster M4 Accessories

The AR-15 variants are loaded with accessory options and Bushmaster has got them all. The Bushmaster Firearms catalog offers individually sold upper and lower receivers for many of their models. Most people stick with the pre-equipped lower receiver, but if you fancy a skeleton or trapdoor stock they’ve got you covered. If you love and trust Bushmaster then check out their catalog which offers other accessories like field repair kits, varying round magazines, enhanced pistol grips, foregrips, slings, and cleaning kits.

Conclusion

At the end of the day, you can’t go wrong with Bushmaster. So much has changed with AR-15s and with Bushmaster itself, but as time goes on they are only getting better. The XM-15 is a great series of guns and the M4 carbine AR-15 variants are no exception. They’re long-lasting, reliable, accurate, and American-made. It’s no coincidence that they are the largest supplier of AR-15 variants in the country. Bushmaster is clearly dedicated to excellence and has engineered a semi-automatic weapon for all types of users with all types of preferences. It’s not only fun to shoot, it’s easy to manage, dependable, and if taken care of properly, you’ll be shooting it for years.

In recent times, there has been wanton criticism and condemnation from the misinformed members of our government and public about semi-auto weapons. One gun in particular has been targeted and blamed more than most: the AR-15. Bushmaster Firearms (the leading supplier of AR-15s in the U.S.) has certainly faced some serious opposition because of this, but they’ve always been able to bounce back – most likely due to their exceptional products. Bushmaster’s world-renowned rifles have been manufactured since the early 70’s and have kept their reputation of creating resilient, quality, and dependable weapons since. Bushmaster has spent years developing their line of pistols and rifles which have been used around the world for decades. Not only are their guns trusted for home defense, hundreds of U.S. law enforcement organizations and more than fifty foreign militaries trust their Bushmasters to keep their citizens safe. Because of their reliable accuracy, Bushmaster weapons are also a favorite for hunters and competitive shooters alike.

As previously mentioned, Bushmaster Firearms has seen its fair share of adversity and although they have been sold several times, their commitment to engineering American-made products has never ceased. Most recently, they were acquired by the holding company Freedom Group who also owns notable brands such as Remington and Advanced Armament. While currently headquartered in a small town in North Carolina (just a short drive from Greensboro), they now manufacture their products in Ilion, New York.

Bushmaster Firearms Overview

Bushmaster’s specialty is without a doubt their impressive collection of rifles. With so many styles and options available, you can easily assemble the rifle of your dreams. Whether you’re looking for something new this hunting season or upping your home defense, Bushmaster has got your back.

Bushmaster XM-15 Rifle Series

This Bushmaster series is a line of AR-15 style semi-auto rifles and carbines. This series consists of several heavy, gas-operated firearms that are effective at up to approximately 600 yards.

• XM-15 QRC – This quick response carbine (QRC) is built to last and comes with a quick detach mount 1 x 20 red-dot optic.
• 16” Heavy BBL A3 Carbine – Completely interchangeable with most AR-15 parts and comes with a detachable carry handle.
• Quad Rail A3 – Beautiful gun with aluminum free-floated quad rail handguard and detachable carry handle.
• M4 Type Patrolman’s Carbine – Relatively light-weight, this semi-auto carbine has been re-marketed to the civilian public as a copy of the Colt M4 Carbine. However, military/governments have access to an assault rifle variant with selective fire.
• 16” Heavy BBL Carbine A2 –The main difference between the A2 and A3 is that the A2 sights are directly installed into the receiver with a fixed carry handle.
• 20” Barreled M16-Type Rifle – Comes in A2 or A3 models. The A3 upper receiver includes a Picatinny mounting rail which enables you to attach most accessories.

Bushmaster ACR Rifle Series

The Adaptive Combat Rifle (ACR for short) is a relatively new assault rifle (developed in 2010) made by both Bushmaster and Remington Arms. Formerly known as the Magpul Masada, the ACR is famous for its quick and easy caliber change.

• 5” ACR Basic Folder Configuration – Bushmaster’s ACR was engineered for longevity and durability. This model is optimal for speed, accuracy, and simplicity. All the major components can be quickly swapped; even the suppression and charging handle can be switched on the go. Although heavier than most AR-15s and less customization options than average, this gun is still a great buy.
• ACR Enhanced – If the ACR Basic is Old Faithful then the Enhanced model is the rookie of the year. Bushmaster improved the handguard for better accessory mounting, and added quick attach mounts for a sling and a great flash hider.

Bushmaster MOE Rifle Series

The Magpul Original Equipment line (MOE) combines Bushmaster’s Carbine gas system with Magpul’s ergonomic engineering to create these highly modifiable rifles. Known for its user-friendliness, the MOEs are also quite accurate and (relatively) light-weight. Each of these models is designed with a sleek 16” chrome line barrel, adjustable stock, enhanced trigger guard, and a rear flip sight.

• MOE M4 – Type Carbine / 16” MOE Mid-Length / MOE Dissipator – Excellent shooting abilities, especially with MOE handguard and pistol grip. Although these three models are nearly identical, the M4 Carbine is slightly lighter than the others.

Bushmaster BA50 Rifle Series

This behemoth of a rifle is extremely accurate at long distances. Take one look at the .50 BMG Caliber, bolt action, 30” barrel and it’s clear what this gun can do.

• BA50 – Weighing in at nearly 9 lbs., this cannon has some serious stopping power. Bushmaster equipped the BA50 with a new muzzle brake/silencer adapter and a foldable steel bipod. The cherry on top is that it disassembles as easy any AR rifle.

Bushmaster Hunting Rifles

These powerful semi-autos are any hunter’s best friend. Bushmaster has reduced recoil by employing a gas-operating system similar to the ARs while maintaining accuracy up to an impressive 200 yards. Easy to use, durable, and strong, this gun is as reliable as they come. But with such distinctions, the $1,500 MSRP is not unjustified.

• 450 Bushmaster Rifle/Carbine – Crafted with a 20” barrel, the 450 Rifle comes with an A2 pistol grip and trapdoor buttstock.
• Varminter – This is the gun for the serious varmint hunter. Its 24” fluted barrel and two 1 ¼” mini-risers for mounting optics can essentially turn this AR style rifle into a sniper.
• Predator – Very similar to the Varminter, but with a 20” barrel. To ensure its accuracy, Bushmaster designed the predator with a vented aluminum fore-end and a free floated chrome-moly steel barrel. The handguards on these firearms are incredible.

Bushmaster Pistols

These carbon fiber constructed pistols are lightweight, durable, and intimidating. Originally manufactured by Professional Ordnance, the Carbon 15’s are loosely designed like an AR-15, and are a distinct piece for any collector to have.

• Carbon 15 – This gun definitely sticks out from the rest. Super lightweight, different caliber options available, and low recoil, make this gun downright fun to shoot. The Carbon 15 has average accuracy, but has proven Bushmaster reliability (unlike its predecessor made by Professional Ordnance).

Bushmaster Accessories

Bushmaster does not disappoint with their accessories. They offer numerous options for upper and lower receivers, special grips and stocks, variant triggers, tons of barrels, mounts, and sights, flash suppressors, and specialty magazines.  Besides for just parts, Bushmaster makes all kinds of kits and tools to aid you in all types of situations whether in hunting or competition. I’ve seen guys come the range with Bushmaster carrying cases and mini scopes, hunters equipped with Bushmaster combat bayonets, and owners cleaning their guns with Bushmaster cleaning equipment. Bushmaster has it all.

What To Look Forward To

Bushmaster is unveiling some serious stuff this year, and I for one am pumped. Some of their new firearm models include the Minimalist-SD and the ACR-DMR. The Minimalist Series is a gun-lover’s dream come true. The 2017 Bushmaster Catalog claims that the new ACR is “built to adapt to anything” and after checking out the specs, they sure as hell ain’t lying. Stay tuned folks.

Conclusion

All in all, Bushmaster Firearms has come a long way since 1973 and has surpassed nearly every obstacle thrown at them. Although they primarily manufacture rifles, it is astounding how much diversity their different models have. It’s hard not to love this American underdog who now is one of the most successful rifle producers in the world. Their weapons are highly sought after by military and law enforcement alike all around the world, as well as by hunters, competition shooters, gun enthusiasts, and those who want to keep their family and property safe. Although not all of their guns are the best of the best, but give me any Bushmaster and I’ll be confident that I have a durable, accurate, and dependable gun in my hands.
