If you have always wanted a large caliber AR pistol for hunting hogs or even just having fun at the range, this Radical Firearms 458 SOCOM pistol might be the one for you. This compact AR pistol comes with a variety of enhancements that make shooting this large caliber extremely fun. The 10” free float handguard has plenty of space for mounting your favorite angled foregrips, lights, or other accessories. The M-LOK attachment system allows you to quickly attach, detach, and rearrange your accessories depending on how you want your pistol set up. This style of handguard helps to protect your hand from the heat generated from shooting multiple rounds simultaneously as well as helps the barrel to cool down faster. The barrel also offers many benefits such as an HBAR profile that helps with accuracy and a Melonite finish that increases barrel life. Attached to the end of this barrel is the Radical Firearms Panzer muzzle brake that helps to tame the recoil of such a large round being shot from a short barrel. This Radical Firearms 458 pistol is a great option if you want a compact hog gun or just looking for new ways to have fun at the range.

This AR-15 style pistol utilizes a pistol length gas system and buffer tube to help reliably cycle the action. The direct impingement gas system uses a stainless-steel gas tube attached to the Radical Firearms low profile micro gas block. The forged upper and lower receivers are outfitted in Mil-Spec components that can easily be upgraded in the future if you want to customize your pistol. However, it does come with a Mission First Tactical pistol grip that is much more ergonomic and comfortable than standard A2 grips. The bolt carrier group is Melonite coated as well as magnetic particle inspected as an added measure to ensure reliability. All you need is your favorite optic and you are ready for the range.
