Push the boundaries of the standard AR-15 frame. Pro2A Tactical’s High-Velocity Distance and Precision Upper lineup is engineered explicitly for shooters who demand sub-MOA accuracy, flat trajectories, and extended supersonic range without stepping up to a heavy AR-10 platform.
Whether you are tracking varmints at 500 yards with the ultra-fast .22 ARC or 224 Valkyrie, ringing steel past 1,000 yards with the modern 6mm ARC, or hunting medium game with the time-tested 6.5 Grendel or 6.8 SPC II, our direct-to-consumer match systems deliver custom-shop accuracy at a competitive manufacturer price point.
The Pro2A Tactical Precision Advantage:
True Left-Handed Precision Assemblies: Maintaining a perfect cheek weld shouldn't mean taking facial gas blowback on every shot. We offer fully mirrored, left-ejecting precision uppers across our entire .22 ARC, 224 Valkyrie, 6mm ARC, 6.8 SPC II and 6.5 Grendel lines to keep southpaw long-range marksmen perfectly focused.
Premium Barrels: Distance requires consistency. Our barrels feature optimized twist rates (such as 1:7 for .22 ARC and 1:7.5 for 6mm ARC) and premium finishes like Salt Bath Nitride to ensure exceptional structural longevity and minimal thermal drift.
Tuned Gas Regulation for High-BC Bullets: Long-range cartridges rely on efficient powder burns. Our uppers feature fine-tuned gas system lengths—extending up to 22-inch and 24-inch rifle-length systems—and optional adjustable gas blocks to smoothly regulate bolt velocity when running heavy, high-ballistic-coefficient (BC) match projectiles.
Type II Bolt Face Integration: Avoid extraction and pressure failures common in piecemeal builds. Every precision upper assembly is optioned with an optimized, headspaced Type II bolt carrier group specifically matched to the Grendel/ARC case rim geometry.
