Alan Adamson Posted October 6, 2011 Share Posted October 6, 2011 it's a long story as to how I got here and I don't have to go here if this is s stupid idea... I've got a cut down 16" rifle length gas barrel... It's actually a really good barrel that the threads were screwed up on and instead of it being cut down to a 17, it was cut to a 16 ... But, I wonder, can they be made to work - reliably? Dwell time seems to be the main issue it appears... I can solve some of that by putting a suppressor adapter on it and and suppressor, but I'm wondering if I can put a suppressor/brake adapter on it and use it as a backup upper if I ever needed it for 3G? Does and adjustable gas block solve any of the issue? Light BCG? ligher buffer/spring, etc? Just curious before I put everything back together.... This is really an SPR type gun that I use for some long distance shooting, I just was thinking maybe I could dual purpose it... or not... I always have another 18" barrel that I can put on this upper if worst comes to worst. Thanks Alan Link to comment Share on other sites More sharing options...

I measured wrong, it's a 17" not a 16" and I know that will work I have one already that works just fine.... duh... Link to comment Share on other sites More sharing options...
dauntedfuture Posted November 19, 2011 Share Posted November 19, 2011 (edited) I called CMMG about a 16" rifle gas set up gun some time ago. They said that you might can get it to work but I would need hot ammo. I shoudl think that a levang or krink comp would provide more gas if required to work the bolt.

Mark Gale Posted November 20, 2011 Share Posted November 20, 2011 The best option would be to bump the size of the gas port. Link to comment Share on other sites More sharing options...
chbrow10 Posted November 20, 2011 Share Posted November 20, 2011 I have a 16" barrel with a rifle length gas system and it works. The gas port has been opened up Link to comment Share on other sites More sharing options...
