What I have here was a CMMG 22lr 16" barrel. It has cuts on both side for right or left hand bolt assemblies. I had ADCO cut and rethreaded 1/2x28 to make it look like a 10.3-10.5" ar15 barrel. So it's about 12" long.
I no longer need it. It has seen ~4000 rounds. This would be great for you to build a 22lr clone of a 10.3" mk18 or something like that.
Comes with FH, fde HG, barrel nut/delta ring, FSB assembly, and the side sling attachment.
Asking $240 $200
