MPA AR-10 Rifles — 416R Precision Stainless | Built and tested in Sanford, NC
Every MPA AR-10 comes standard with a spiral fluted 416R stainless barrel, forged receiver, 3.5 lb single-stage trigger, and muzzle brake — all installed and function tested before it ships. The AR-10 platform delivers significantly more energy and reach than an AR-15. MPA builds on that foundation with materials and components that most manufacturers treat as upgrades, delivering exceptional accuracy across a variety of shooting applications.
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.
About MPA AR-10 Rifles
