I've got a New in the Box CMMG Hand Guard for a 308 type AR.
It is 15" in length and is new in the box. It's the RKM15 Mk3 model.
I accidentally bought it for an AR15 build, so would also be open to trades for an similar AR15 hand guard.
I know this is not compatible with the Armalight AR10, but from what I've read, I believe it should work for the DPMS pattern or LR308, etc, but please check yourself as I could be wrong. I only know it is not Armalight compatible.
Comes in the box with everything as new.
Asking $175 shipped.
Let me know if you have any questions and if you would like a pic, send me a PM with email and/or cell number and I can text or email you a picture. Thanks.
