If you are looking for an affordable and reliable AR pistol chambered in 5.56, Radical Firearms has the one that you want. It comes with everything you expect from Radical like Mil-Spec forged aluminum receivers assembled with Mil-Spec components and an ergonomic Mission First Tactical pistol grip. The M4 flat top upper receiver combined with the Radical Firearms FCR free float handguard is fully monolithic and are indexed together, so you don’t have to worry about alignment issues that can affect your zero with iron sights. The FCR rail features M-LOK attachment points along the sides and bottom that enable you to quickly attach your favorite accessories at almost any position. This 10” M-LOK rail almost covers the entire length of the 10.5” barrel, so you can attach a light as far forward as possible to prevent the light from getting obscured by the barrel or handguard. The barrel is made from 4140 chrome moly steel and has a durable Melonite finish that is harder than chrome while providing a lower coefficient of friction for a longer barrel life. The 1:7 twist barrel is very versatile and is optimal for stabilizing heavier 5.56 NATO rounds. The Radical Firearms complete 5.56 AR pistol is a great affordable option to add to your collection.

Just like the barrel, the M16 cut bolt carrier group is Melonite finished to prevent wear and provide an extremely smooth surface that is easy to clean. With a bolt and barrel extension sharing the same finish, you will see much less wear between the locking lugs and can expect a much longer lifespan of your components. The bolt head is magnetic particle inspected as well to ensure the dimensions are Mil-Spec for optimum reliability. The BCG is paired with a pistol length gas system and a smooth pistol length buffer tube. This Radical Firearms AR-15 pistol might just be the one you are looking for.
