Description
Few rifles carry the reputation the Barrett .50 does, and the M107A1 is the most refined version of that legend yet. Built on over 35 years of development and shaped by feedback from military end users, this recoil-operated semi-auto sheds four pounds compared to earlier M107 rifles while adding strength where it counts. The 20-inch fluted barrel is fully chrome lined in the bore and chamber with a 1:15 twist, and the whole rifle wears a durable black Cerakote finish. At 48 inches overall and 27.4 pounds, it is the compact barrel option in the M107A1 lineup, which makes it a bit handier to move and transport than the 29-inch version.
Suppressor-Ready From the Ground Up
What really sets the M107A1 apart from the old M82 pattern is that Barrett designed it around suppressed fire rather than treating it as an afterthought. The steel four-port cylindrical muzzle brake doubles as a quick-detach mount for the Barrett QDL suppressor, and the redesigned bolt carrier group and buffer system are built to handle the different operating conditions a can creates. Even unsuppressed, that brake takes a serious bite out of felt recoil, which is a big part of why these rifles are more pleasant to run than their size suggests.
Smart Details on the M107A1 Platform
The aluminum upper receiver carries an integrated 27 MOA optics rail, giving long-range optics the extra elevation needed to stretch the .50 BMG way out there. Inside, the bolt carrier rides on a hardened steel anti-wear strip, and a titanium barrel key adds durability without extra weight. A thermal-guard cheek piece keeps your face off hot or freezing metal, the fixed stock wears a Sorbothane recoil pad, and flip-up backup sights come standard. Barrett rounds out the package with a 10-round detachable magazine, adjustable bipod, rear monopod, and a Pelican hard case, so you are set up for the range or the field the day it arrives. For big-bore enthusiasts and serious long-range work, this is the benchmark semi-auto fifty.

Frequently Asked Questions
Is the Barrett M107A1 suppressor ready?
Yes, and that is really the whole point of the A1 upgrade. The four-port cylindrical muzzle brake serves as a quick-detach mount for the Barrett QDL suppressor, and the bolt carrier group and buffer system were redesigned specifically to run reliably with a can attached. It shoots great unsuppressed too, but it was engineered with suppressed fire in mind.
How is the M107A1 different from the original M82/M107?
The M107A1 trims about four pounds off the older design through updated materials like a titanium barrel key and aluminum upper receiver, while adding strength in high-wear areas. It also adds the QD suppressor-compatible muzzle brake, a hardened steel anti-wear strip inside the receiver, and a thermal-guard cheek piece. Same iconic look and recoil-operated action, just refined across the board.
Do I need a special scope mount for the 27 MOA rail?
No, the 27 MOA cant is built into the receiver rail, so standard rings or a one-piece mount work fine. That built-in elevation gives your scope extra adjustment range for the truly long shots the .50 BMG is capable of, so you will not run out of turret before you run out of distance.
What comes in the box with the Barrett M107A1 18062?
This model ships with one 10-round detachable magazine, an adjustable bipod, a rear monopod, and a Pelican hard case. That covers your basic field setup from day one, so an optic and ammo are all you need to add before heading to the range.
