The Aero Precision BREACH® is a rugged, ambidextrous, precision-manufactured charging handle for the AR15 platform. The BREACH’s design utilizes a reinforced 7075-T6 aluminum bar that is up to the most demanding tasks. Its ambidextrous levers feature a patent-pending, dual spring system, that directs the force-of-use into the robust charging handle body. This allows the shooter to use a one-sided charging technique without compromising the part — a pitfall for traditional mil-spec charging handles. The small lever configuration provides a low-profile, easily gripped interface that is comfortable when slung and can be actuated effortlessly from either side of your rifle. This BREACH® Charging handle features colored anodizing on the levers. While imperfections are few and far between, there are occasional variances in the finish. This can include variances in the lever itself, or slight differences in color when comparing two charging handles from different batches. To learn more about colored anodizing please visit

Our state of the art M4E1 platform starts here, with the M4E1 Upper Receiver. The M4E1 upper receiver is a one-piece design combining the handguard mounting platform with the upper itself. Through superior engineering, we have condensed the parts needed to mount a free-floated handguard to a mere 8 screws. Since the handguard mounting surface and upper are of the same forging, not only is it a stronger system, but we are able to make additional lightening cuts to save weight and allow for more efficient cooling. Ease of installation – Simply insert your barrel assembly into the M4E1 upper, tighten it using the provided barrel nut and wrench, slide your rail on and tighten the rail screws. Within minutes you have a modular, free-floated rail. FEATURES: M4 Feedramps .250 takedown pin holes Lazer engraved T-marks Comes assembled, with dust cover and forward assist installed M4E1 SPECIFIC DETAILS: Handguard mounting platform

The Aero Precision PRO 5.56 AR-15 Bolt Carrier Group is a high-quality addition to your existing rifle or as the building block for your next AR build project. Aero has manufactured the PRO Bolt Carrier Group with purpose and has designed it with components to increase durability. The bolt is heat treated and machined from 9310 steel. While most bolts have a swagged cam pin channel that removes material in the manufacturing process, making them weaker, the PRO features a counter bored channel which also eliminates the need to force the pin and avoids a common failure point for bolt carrier groups. The cam pin is also indexed which ensures that it is properly staked during assembly/disassembly and doesn’t wear unevenly during operation. If you want to build a no frills, reliable duty rifle, you can’t go wrong with this Aero PRO BCG. Features: Machined from 8620 steel (carrier) and

The large lever configuration provides an extended operating surface, perfect for a user with bigger hands, or someone who wants a larger surface for manipulation of the charging handle. Learn more about the BREACH® Charging Handle FEATURES: Ambidextrous Controls: Ergonomically designed 7075 Aluminum levers allow the user to easily charge their firearm with either hand, while remaining low profile and comfortable when slung. Robust Construction: Reduced chamfer angles on the 7075 Aluminum reinforced bar design provide a strong foundation

The Aero Precision Adjustable Gas Block allows the user to finely tune their gas system for any application. This is particularly useful for managing excess gas to reduce blowback on suppressed firearms, or competition builds where the shooter is looking to mitigate recoil. FEATURES: Standard low-profile design provides great fit under slim profile free float handguards including the Aero Precision ATLAS series of handguards Adjustment screw is held in place by a spring and detent, providing repeatable audible “clicks” upon adjustment removing the need for secondary set screws that can come loose under recoil Custom machined stainless-steel adjustment screw provides 15 gas adjustment settings Carbon fouling is channeled to a sacrificial chamber to help prevent carbon locking, as well as provide an access point for solvent in the event carbon locking does occur User-serviceable design allows for service and cleaning of the gas system SPECIFICATIONS: Machined from 4140 steel Nitride
