Built for shooters who want long-range AR-15 performance without building it themselves.
Why 6.5 Grendel
More range than 5.56 or .300 Blackout
AR-15 platform, AR-10 reach
6.5 Grendel retains significantly more energy and resists wind drift far better than 5.56 or .300 Blackout past 300 yards. The 18" barrel maximizes velocity and consistency downrange — delivering the reach of a larger platform in a standard AR-15 complete rifle.
Better than .223 for hunting
Ethical performance at distance
.223 is marginal for deer-sized game at distance — 6.5 Grendel delivers the energy and bullet weight to take game ethically past 400 yards. The MPA complete rifle arrives with trigger and muzzle brake already installed, ready for the field without additional setup.
Why MPA
Barrel
416R precision stainless
Better corrosion resistance and barrel life than standard chrome moly — the same steel used in match-grade barrels at twice the price.
Spiral fluted
Standard on every rifle 16" and above
Reduces barrel weight and improves heat dissipation during sustained fire. Most manufacturers charge extra for this. MPA includes it standard.
Trigger
3.5 lb single-stage, included
A $100+ upgrade on most rifles. MPA includes it standard — S7 tool steel internals, no take-up, crisp break, short tactile reset.
Quality
Function tested in Sanford, NC
Every rifle is fired and inspected before it ships. Covered by the MPA Precision Standard lifetime warranty.
