Radical Firearms® SOCOM 556 Semi-automatic AR-15 Rifle

The Radical Firearms SOCOM 556 Rifle combines mil-spec receivers, a SOCOM-profile barrel, and free-float handguard to create a budget-friendly AR-15 that flat-out performs. The 4140 CmV steel barrel features the versatile 1:7" twist—the same used by the US Military in the M4 Carbine—which works well with common 55- and 62-grain projectiles, and will stabilize bullets up to 90 grains. That means you have lots of options for suitable ammo.

The SOCOM also comes outfitted with the MFT Minimalist stock, which features an angled non-slip buttpad for faster presentation, even with body armor…all while weighing under 6 ounces. The 15" FCR free-float handguard serves as a solid platform for modern M-LOK compatible accessories, and won't negatively affect accuracy.

Based in Stafford, Texas, Radical Firearms produces almost every rifle component in-house—meaning they don't have to pay a mark-up for the long list of essential parts. That means they can offer a much nicer rifle than other manufacturers in this price range—and the quality shows.

  • SOCOM-profile 4140 CMV steel barrel with Melonite finish for corrosion resistance
