Note: This barrel does not meet the minimum 16” requirement and is subject to all NFA rules and regulations.

Whether you are building an AR-15 pistol or registered SBR, you can’t go wrong with a Bravo Company barrel. This 12.5” AR-15 barrel is made to the highest standards for reliability in harsh conditions and versatility with multiple ammo types. BCM made this barrel with a carbine gas system because it has increased dwell time out of a 12.5” barrel compared to a mid-length, which means that more gas will impact your BCG to ensure that it cycles properly. The 1/7 twist rate was specifically chosen for this BCM barrel because it can effectively stabilize the popular 62gr 5.56 ammo as well as cheaper and more common 55gr bullets. Another way that Bravo Company ensures reliability is the M4 feed ramp barrel extension. The feed ramp angles are modified as well as lengthened to ensure proper cycling of ammo and is standard on all BCM barrels. If you plan on building an AR pistol or SBR, this Bravo Company USA barrel might just be the one for you.

Another popular term thrown around when talking about barrels is chrome lined bore and chamber. This process is used to create a surface that is harder than the cmv barrel steel. The main point of this is not to increase accuracy but to increase reliability. The hard surface aids in extraction, chambering, and reduces fouling and corrosion, resulting in an extremely long barrel life. The outside of the barrel is also parkerized with a manganese phosphate finish that facilitates oil absorption providing extra resistance to corrosion. The government profile is designed to be a lightweight alternative to HBAR barrels while still being compatible with M203 mounting systems.

Expect nothing less than professional grade weaponry from Bravo Company Manufacturing, one of the nation’s largest stocking inventories of AR-15, M4, and M16 parts and accessories. Their products have been used by many United States law enforcement agencies, US Border Patrol, HQ SOCOM, US Army, US Navy, US Airforce, US Marines, US Coast Guard, and more. They believe in providing responsible citizens with the means to defend themselves and will continue to do so for many years to come.

Worth twice the money


I have a little more than seven thousand rounds through this barrel in about a year now so I feel pretty confident with my opinion on this barrel. In short it is an amazing barrel.
<br>To go in detail, this is the best barrel I have owned thus far. The gas port is perfect, ensuring function from lower powered ammo like steel cased tula, while still keeping excess gas from full powered M855A1 out of my face.
<br>In addition to its stellar performance shooting up close I've also taken in out to 500yrds on a 66% Ipsc steel target. Shooting with a 1-6x I was able to get consistant hits when I could get a proper hold.
<br>All in all, its a wonderful barrel that is more than worth the money.

My new favorite build barrel

I did my research and ordered this specific BCM barrel length for my gun game activities. After zeroing it with a PA 1-6x ACSS scope, I took my new 12.5 BCM Aero Precision M4E1 enhanced AR pistol to the 2020 Tactical Games at Shooter's Guantlet. It ran flawlessly. Not surprisingly.
