Probably a dumb question . If I am adding an extension to a barrel to increase the rifle OAL, say a 1" extension to an 8" barrel, do I enter 8 for the barrel length or 9?
Barrel length is based upon permanent length. If not pinned/welded or silver brazed, the length is to the end of the threads- muzzle device is not included.Probably a dumb question .

Ok. I have an 8" barreled AR pistol - but - I am using a Just Right Carbine buffer tube (for the SBR) that is 1" longer (will have to add a spacer behind the buffer spring) and will make up the difference with a barrel extension. So that will have to be like 9.5" or so after permanent attach. I will need to do some measurements. Thanks.Barrel length is based upon permanent length.

I am the MDS'er who proved a JRC buffer tube and a long LOP buttstock can get a 8.5" barrel to 29" OAL. Look into the longest LOP AR stocks and I'm sure you can pull it off. Luth AR makes a really long one.Ok.

Yep. I saw it and ordered one. I think it was a thread for an MP5 pistol (?). I forget.I am the MDS'er who proved a JRC buffer tube and a long LOP buttstock can get a 8.5" barrel to 29" OAL.

Well - this brings up a great point. I could re-purpose the lower all together. But no, I already sunk a bunch of money into this thing, and it is a ton of fun to shoot. I am concerned about a barrel extension not being straight and causing a baffle strike. So if this can be solved by a 16" LOP, whatever, I'd rather do that.Probably less effort just to swap to a 10.5Bloodline 10.5" 300 Blackout Barrel | Rosco Manufacturing

My bad. I saw Smokey's post and reacted to that.I could always use an extra 300 Black upper. But yeah - this one is a CMMG 45ACP.
Is there a barrel extension that will work on your gun?Probably a dumb question . If I am adding an extension to a barrel to increase the rifle OAL, say a 1" extension to an 8" barrel, do I enter 8 for the barrel length or 9?
Oh dip, awesome gun.It's a CMMG radial delayed blowback 45 ACP so barrel choices are limited.
I think this is a great strategy, but it's not clear to me any more what constitutes a pistol configuration for an AR and how that may change yet again in the future. From a shooting standpoint, I am not a fan of pistol braces, but am glad we adopted them as an alternative for shooters that do find them useful. I like the three lug you posted.Me, I'm keeping my pistols as pistols until which time, I can leave this paradise know as Merryland. Then I will SBR them, which was always my want.
