One in seven inch twist improved polygonal rifling, 300 Blackout Noveske Match chamber, extended feed ramps, bead blasted finish, pistol length gas system, gas tube, Pinned Low Profile Gas Block, 5/8x24 threads. Medium contour weight: 31 ounces. Sixteen inch Noveske 300 AAC Blackout is designed to run optimally firing both subsonic and supersonic ammunition unsuppressed while keeping subsonic suppressed reliable. It may not reliably cycle the action under adverse conditions with subsonic ammunition. Barrel is tuned to lock back on the last round using subsonic 220 and 208 grain ammunition without a sound suppressor. The use of a sound suppressor with either subsonic or supersonic ammunition may cause the firearm to operate with more gas than needed. Barrel installation should be performed by a qualified gunsmith. Installation of the gas block dowel pin and gas block is required to complete the assembly process.
