A2 Style 20 Inch Government Profile Barrel
This government profile barrel provides excellent velocity for 5.56 rounds, with a full 20 inch barrel and a 1:7 twist rate. The rifle-length gas system gives the shooter a slower, gentler push in recoil than carbine and midlength gas systems, too. Add in that you’re getting Ballistic’s Sub-MOA guarantee with match ammunition, and you’re looking at a barrel capable of excellent accuracy, with very low recoil in your rifle.
