Barrel Threading

Barrels are indicated to .0002 T.I.R.  on the muzzle end. Thread diameters vary depending on barrel diameter and caliber. We require .100 thousandths shoulder on threaded barrel. All barrels are threaded and checked with ring gauge to ensure proper thread dimensions. Before we remove the barrel from the lathe, we install a direct thread silencer from our inventory of silencers. Once we install the silencer, we inspect thread concentricity to the bore with alignment rods to ensure we did everything possible to prevent any issues with baffle strikes. Standard thread pitches we use are 5/8x24, 9/16x24, and 1/2x28. we sell adapters as necessary.
