PRO2A 8.5" 458 Socom 1/14 Pistol Length Melonite M-LOK AR-15 Upper with Flash Can
By Pro2A Tactical | Made in the USA
Massive Big-Bore Firepower with Directed Muzzle Control
The Pro2A Tactical 8.5" .458 SOCOM Upper Receiver with Flash Can delivers devastating hard-hitting performance in an ultra-compact, maneuverable package. Ideal for AR-15 pistol builds or registered short-barreled rifles (SBRs), this configuration is anchored by a premium 8.5-inch 4150 Chrome Moly Vanadium barrel. The 1/14 twist rate is specifically optimized to stabilize heavy-grain big-bore projectiles with pinpoint consistency. Treated with an advanced inner and outer Melonite (QPQ Nitride) finish, the barrel offers extreme surface hardness, superior corrosion resistance, and effortless cleaning.
This unique model comes equipped with a slimline muzzle **Flash Can**. This dedicated device redirects the massive blast wave, noise, and concussive gases completely forward away from the shooter, making it significantly more comfortable to run at indoor ranges or short-range tactical environments.
