This Radical Firearms 7.62x39 AR Pistol comes with all the features you expect from a Radical Pistol like an ambidextrous safety selector and extended bolt release, however, it comes with an M-LOK handguard exclusive to Primary Arms. This 10” free float handguard features a full length picatinny top rail and has anti rotation tabs that index with the 7075-T6 aluminum forged upper receiver. It also attaches with a steel barrel nut and features lightening cuts to reduce weight. The handguard covers the 10.5” barrel and carbine length gas system. The barrel has an HBAR profile and features a durable Melonite finish. Attached to the end of the 4150 Chrome Moly Vanadium barrel is an A2 style flash hider with a 5/8x24 thread pitch. The 1:10 twist rate is optimal for stabilizing the .30 caliber rounds. Now you can enjoy the popular 7.62x39 round most commonly found in AK-47 type rifles in the more modular AR-15 pattern pistol.
