The Ruger AR-556 is now available in pistol form. With a 10.5” barrel and SB Tactical SBA3 stabilizing brace, this compact firearm is a great option for your next truck gun or home defense gun. It comes with all the features of the full size rifle like the 4140 chrome moly steel cold hammer-forged barrel. This barrel has a 1:8 twist rate for stabilizing a wide variety of bullet weights from 35 up to 77 grains. The black oxide finish protects the carbon steel from rusting and is durable enough to prevent wear. Threaded 1/2x28 with an A2 style flash hider to help reduce the bright fireball common with shorter barrels. The carbine length gas system is necessary for the short barrel length to ensure reliable function with all types of ammo. The 9” M-LOK free float handguard protects the gas tube from getting bent and protects your hands from heat after a long string of fire. M-LOK slots along the sides and bottom allow quick attachment of lights or angled forward grips (do not attach a vertical foregrip as that changes the classification to AOW and requires an NFA tax stamp). Attached only at the barrel nut, this handguard allows the use of bipods or rests without changing the point of impact. Why file for an SBR when you can pick up this Ruger 5.56 AR Pistol today without the hassle.
