How long is the M4 with a 16 inch Barrel?

[russ69]

This new 30 inch requirement has me puzzled. How long is the average M4 with a 16 inch barrel, A2 flash hider and the stock collapsed?

An AR with a carbine buffer tube and a 16" barrel without a muzzle device is over 30"

It's fine

What do you mean. New ?

What do you mean. New ?

The AW regs have it written slightly different then it was prior.

Yes, the way you measure the 30 OAL has been changed to now include permanent attached muzzle devices.

In practice, this tends to only effect bullpups and rifles with folding stocks and extended flash hiders.

What new is that in order for any muzzle device to count towards the >30" OAL, the muzzle device has to be permanent. OR, registered as an assault weapon.

Once you have a registered assault rifle, there seems to currently be a consensus that your AW now only needs to be >26" with a >16" barrel. So that means extended flash hiders can come off.

Gotta get caught up on some reading.

I believe it has been 30" OAL for a while now,,,not a new 2017 thing!?

[tonyxcom]

Yes, always been 30" OAL.

The only change this year is that if you use a muzzle device to get there, it needs to be perm now.

Mine is about 32 1/4". The flash hider adds about 1 1/4", so nominally it's about 31" to the end of the barrel.

My car-15 with 14.5" barrel +1.5" Flash Hider making a legal 16" barrel and standard 4 pos stock is 31.5". I used to keep it in a 30" zippered discrete case and it pushed out the sides slightly.
