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.
SHOP Pro2a Tactical's huge selection of 6.5 Grendel Uppers. 6.5 Grendel is a great round for long range hunting/shooting, offers ballistics that rival a 308 Win at certain distances. It's high bullet coefficient offers great effective range and velocity. All our 6.5 Grendel Uppers are Type II Chamber which is the original chamber designed by Alexander Arms and made right here in the USA. Pro2a Tactical Uppers are backed by a Limited Lifetime Warranty.
