Polished M4 style feed ramps aid in reliable feeding. 6.8 SPCoffers four-groove button rifling with a 1-11" twist rate for excellent performance with bullet weights from 85 to 115 grains. 16" barrel features a mid-length position for the pre-drilled gas port which is precisely sized for 6.8 SPC. 11.3" barrel features a carbine length gas system. Extra thickness under handguard resists heat warping. Requires 6.8 SPC bolt and magazines. Available in either 16" or 11.3" length.
