About This Firearm
The Aero Precision M5 is a flat-top semi-automatic .308 Winchester built for range shooting and deer hunting. Aero Precision no longer lists complete M5 rifles, so this is a used buy. Its 16-inch barrel is 4150 chrome moly vanadium steel with a QPQ corrosion-resistant finish, on a mid-length gas system.
It came with one 20-round Magpul PMAG, a Magpul STR stock and an M-LOK handguard, over an 8620 steel bolt carrier group, with an A2 birdcage flash hider on the muzzle. Measure the muzzle thread before ordering a brake or a suppressor mount.
If you’re cross-shopping, the Ruger SFAR is a used buy at 6.80 lbs and 37.25 inches overall, with a four-position gas regulator and a wrench for it on the rifle. The Sig Sauer 716i Tread has an MSRP of $1,519.99 and weighs 8.50 lbs, and Sig’s Infinite Guarantee goes with it, needing no receipt and no warranty card.

Strengths & Limitations
- The bolt carrier group is 8620 steel, which is the standard carrier material for the pattern.
- Aero Precision built the rifle from its own receiver set and handguard, which it sells as components in their own right.
- The A2 birdcage flash hider is a standard AR-308 part, so changing it is a wrench job once the thread is known.
- At 16 inches, this is the short end of .308 AR barrel lengths, so velocity trails the longer barrels in the pattern.
- The Magpul STR stock adjusts for length but has no adjustable comb, so cheek height under a tall scope mount is fixed.
- Complete M5 rifles are gone from Aero Precision’s line, so a used rifle comes with whatever trigger and sights a previous owner chose.
