I just ordered a new Bushmaster A2 16" upper Hbar with a birdcage FH I am going to take the FH off and put on one of those nifty thread hiders. . . I don't have the item in my hand yet, but want to order the thread protector before it even gets here. .. . . . SO My question is, how long are the threads, I can order these in a variety of lengths. I am assuming they are 1/2 28TPI am I correct in this? I am guessing that I need to get one like 1/2 inch long. . . can someone tell me for sure? Thanks. |
