Aero Precision M5 AR-10 .308 Win Custom 16" Semi-Automatic Rifle
This Aero Precision M5 stands out as a purpose-built AR-10 chambered in .308 Winchester, upgraded for comfort and control. A 16-inch 4150 CMV steel barrel with QPQ nitride finish anchors the build, while a slick-side upper keeps weight down. Factory SR-25 magazine compatibility, an ATLAS S-ONE 15-inch free-float M-LOK handguard, and user-added features such as a Limbsaver recoil pad, bipod, and ambidextrous safety selector make this rifle ready for range work or field use right out of the case.

The heart of this rifle is Aero Precision’s 7075-T6 forged receiver set, finished in hard-coat anodized matte black for durability. The slick-side upper deletes the forward assist for a clean profile while retaining a full-length Picatinny top rail for optics.
The 16-inch barrel uses 4150 CMV steel, a mid-length gas system, and a 5/8-24 UNEF threaded muzzle for brakes or suppressors. A 1:10 right-hand twist stabilizes a wide range of .308 projectiles.
A 15-inch ATLAS S-ONE free-float handguard, machined from 6061-T6 aluminum, provides M-LOK slots along the sides and bottom plus a continuous top rail. The dual-screw wedge-block mounting system keeps the handguard tight to the receiver for repeatable accuracy.
Ergonomics are enhanced with a Magpul MOE six-position stock fitted with a Limbsaver recoil pad, an MOE K2-style grip, and an ambidextrous safety selector. The nickel-boron-coated bolt carrier helps ease cleanup and promotes reliable cycling.
