Can a carbine upper be cut down?
I have a standard carbine upper with a 14.5 bbl that had its p&w flash hider removed. Fixed front site. Can I have this cut down and a new fh threaded on for a pistol build upper? Was thinking as short as possible in front of front site.
I’ll snap some pictures tonight after work if needed to explain.

Re: Can a carbine upper be cut down?
Barrel length of a AR "Rifle" has to be a minimum of 16". A 14.5 barrel is only legal on a "Rifle" provided the flash hider is welded onto the barrel to meet the 16" barrel length.
Two exceptions:
If it's was originally a AR "Rifle" (with a stock), then you can apply for the $200 tax stamp to turn it into a Short Barreled Rifle (SBR) and reduce the barrel length to less than the 16" requirement.
If it was originally a AR "Pistol", then you can have a barrel less than 16", but you can't put a stock on the "pistol" build without it turning it into a SBR (requiring the $200 tax stamp).
So, depending on the above variables you're AR may currently be illegal if it's assembled with only a 14.5" barrel.Last edited by Hawk; November 5th, 2019 at 04:15 PM.

Re: Can a carbine upper be cut down?
You can get that one cut down but It would be easer to just buy a barrel the length you want and sell the 14.5" one, unless the end got destroyed removing the pin and welded flash hider. You need a pistol lower or an SBR to have that upper without the correct length flash hider welded on. Taking it off without a pistol or SBR lower is not a good idea...

I'm thinking you could use the shortened barrel on A DIFFERENT LOWER that is starting it's life as a pistol.
Since a rifle must always remain a rifle (aside from SBR/submitting forms), you couldn't use the original "carbine" lower and simply put a pistol buffer tube on it and use that shortened barrel and say that it's now a pistol.
The shortened barrel could only be used to build an SBR, or a pistol - but not using the original lower.
Then just add a carbine/rifle barrel to the original carbine.
I'm pretty sure I have it right, but see what other responses you get as well.I called to check my ZIP CODE!....DY-NO-MITE!!!

Re: Can a carbine upper be cut down?
Understood. Yes, I should have been more clear. I am aware that this needs to go on another lower, have a stripped one being built out for a pistol. My question was more specifically can the upper I have be cut down and used for the pistol upper? My thought was it may be a little less expensive to have a gsmith cut down the tube and install a muzzle device rather than buy or build another upper.

Pistol barrels can be had for $50-70 bucks doubt you'll find a smith to cut crown and thread for that.

Definitely cheaper and easier to just use a new barrel.
