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.
