I've got a 16" barrel on a preban M4gery. It has the 203 cut in it and a 1/7 twist. I work in a fabrication dept and was wondering if I could have one of the lathe operators cut down the barrel to 14.5" and rethread the end.

If this is possible, it would save me some $$$ and the hassel of storing a barrel.

Is this a "can do" proceedure? Thankx.

Yeah, you can do it. Just make sure you have the tools to take the barrel off and put it back on, and you perm. attach a muzzle device.

Yes it can be done - but I'd have it done by a proffessional. Someone whos done it many times. Sombody like Kurt (see Kurt's Kustom in the Industry section).

There is a difference in the length of the raised area of the barrel, forward of the GL cut, between the 14.5"(1 1/2") and 16"(3 1/8"). This area can be turned down as well. A professional maachine shop can do the cut/crown/thread and turn down job, but the barrel will still need to be re-parkerized. This is why you should use a gunsmith, as they will already be set-up for this type of work. I send all my gunsmith work to Mike at Ohio Rapid Fire ( [url=ar15.com/forums/topic.html?b=7&f=25&t=139752] me223[/url] on the EE!)

What about different flash suppressors? When I see a 14.5 barrel for sale, it always mentions "with a permanently fixed phantom F/S, this is a legal 16" barrel." I think they must have a hard on for the phantoms-but I want a Vortex. Ya...I see what you mean about the raised area near the front of the barrel. I guess it does'nt have to look exactly like a M4 barrel. I don't think a bad guy is going to say to much if it has to get pointed at him.
