Do you leave the same length, .65”, of threads?

I am also ordering a pin and weld so I want make sure I allow enough barrel length to make 16”.

The muzzle device is a Griffin   2.25” flash hider, which I believe adds 1.6” of length from the shoulder. Or would you recommend cutting to 14 5/8” to be certain?

Also going to add having my FSB shaved down while its there. Should I include the pins with it or keep them at home? This is an LMT barrel so pins are straight and a mf’er to deal with.

Just want to make sure I get my order right before sending everything in.

Thanks for your time,
Mike

The 3 prong FH was timed even though it didn’t need to be, that’s attention to detail.
I’m glad I went ahead and had you shave the fsb instead of doing that myself, no way I could have made it look that good.

Thanks again,
Mike
