I’m pretty sure I’m right about this, but just want to verify this with the rifle brain trust. I’m picking up a BCM AR upper. The original barrel was cut to 14 inches and a muzzle device that measures 2.25 inches was attached to it. As long as the device is pinned and welded into place, this is considered a legal rifle? | ||

Agree with Mike. If you want a true "barrel length", assuming it is actually pinned/welded, drop a dowel down the barrel with the bolt closed. Measure. ________________________________________ -- Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past me I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. -- | |||

Depends. Is the 2.25” the total length of the muzzle device before being P&W, or does the muzzle device extend 2.25” beyond the end of the barrel? The muzzle threads have about 0.6” of overlap, so a muzzle device with a total unmounted length of 2.25” will only add 1.65” to the barrel length.This message has been edited.

If you are worried, you could go with a longer muzzle device like a Surefire Warcomp or 3 Prong that comes in at 2.6 inches. | |||

Yeah, the bottom line is, the total barrel length (counting the P&W muzzle device) must be a minimum 16 inches in order to pass the non-NFA status. Q | |||

I’ll be sure to verify it once it arrives. The Surefire WarComp looks nice. I may just get it anyway! Thanks guys! | |||

It's going to depend on how deep the threads are on the muzzle device. I agree with the person who suggested dropping a dowel down the barrel with the bolt closed. | |||

Still finding my way |
If it's BCM then it's fine. All their uppers I've seen are actually 14.5". Not 14. I have 2 and both are legally 16.2" and have been 100% reliable. | |||

It sounds like the barrel may have originally been longer and was cut to 14". | |||

It sounds like it has an extended flash hider on it at 2.25" The 14.7" I have uses a regular A2 flash hider to bring it to 16.1" overall Length of that one is 1.750", crush washer adds another .22" | |||
