Radical Firearms SHR Features The Radical Firearms SHR runs on a direct impingement system paired with a 16 black Melonite treated chrome moly vanadium barrel giving the rifle corrosion resistance and a smooth reliable cycle of operation in 5.56 NATO. The 1:7 twist rate stabilizes a wide range of bullet weights so shooters can run everything from light varmint loads to heavier match projectiles without stability concerns. An A2 flash hider caps the muzzle taming flash signature for better follow up shot visibility and the barrel is threaded 1/2x28 for future muzzle device upgrades. A mil-spec trigger and a selector switch safety round out a dependable familiar manual of arms for anyone who has trained on an AR-15 platform. The 15 M-LOK free float handguard keeps the barrel from contacting the rail under stress which helps maintain accuracy as the rifle heats up during extended strings of fire while still offering plenty of mounting slots for lights grips and other accessories. An OD Green aluminum receiver set with a Picatinny top rail sets this rifle apart visually while keeping it fully compatible with standard optics mounts and backup iron sights. The B5 Systems Bravo 6 position stock adjusts quickly for different shooters or body armor configurations and the matching B5 Type 23 grip provides a secure textured purchase. At 6.5 lbs and 33 overall with a 30-round capacity this rifle balances maneuverability and firepower for range competition or home defense use at GrabAGun.
