On a typical flash suppressor for an AR15 what size hole to I drill and what size die to I use to cut the threads??? I know they say the threads are 1/2x28 but that doesn't mean squat to me LOL

But as stated, threading a FS is not a free hand thing since the threads need to be square to the Bullet channel through the FS, or your going to end up with a bullet strike. |

Really needs to be turned on a lathe. The bore and threads must be concentric to the projectiles path. Reaming before internal threading is not necessary and does not need to be done. All that does is ensure the minor diameter (hole) is exactly what it should be for size and also makes the hole round if for any reason you used a jobber drill that did not drill round.
What would you want to thread a flash hider or muzzle device? Can you not find one available or do you just want to make something? I would not recommend doing it without a equipment. |
