Harvest the full medium-range potential of the modern sporting rifle platform without NFA complications or home-built unreliability. The P2A PATRIOT 16" 6.5 Grendel Mid-Length Melonite M-LOK Rifle is a fully assembled, factory function-tested complete firearm engineered to maximize the incredible long-range and hunting capabilities of the 6.5 Grendel cartridge. Built around a standard, non-NFA legal 16-inch 4150 CMV steel barrel, this model features an optimized mid-length gas system. This choice tames system cycling speed by increasing internal pressure dwell time, producing a noticeably softer recoil impulse and reducing long-term component wear. Featuring a lightweight free-float M-LOK handguard and matching premium internal components, this rifle arrives ready for the field or range right out of the box. Proudly 100% designed, machined, and precision-assembled in the USA.

The P2A PATRIOT 16" 6.5 Grendel M-LOK Rifle directly eliminates the risk of component tolerance stacking and mechanical friction often found in piecemeal home configurations. Alternative calibers like the 6.5 Grendel require highly specialized bolt head configurations and perfectly balanced gas blocks to feed and extract heavy-cased ammunition cleanly. Sourcing separate parts from different e-commerce brands frequently results in failure-to-feed issues or dangerous headspacing variations. Pro2A Tactical solves this problem completely by custom-matching, headspacing, and testing the entire operating group as a unified firearm package before it leaves the factory floor.
Furthermore, selecting a full-length 16-inch configuration paired with a mid-length gas system provides absolute ballistic efficiency for the 6.5 Grendel round, enabling it to maintain flat supersonic trajectories over long distances while freeing you from restrictive short-barreled rifle registrations or pistol brace rules. Built to withstand punishing field environments, the combination of forged 7075-T6 aluminum structural surfaces and a chemical Melonite-hardened core ensures long-lasting field dependability. Backed completely by Pro2A Tactical's signature Lifetime Factory Warranty and built with 100% American craftsmanship, the PATRIOT rifle offers premium, defense-ready security with absolute structural confidence.
