View Full Version : WTB: Reverse Offset Pin for AR15 Colt upper

01-28-2009, 9:23 PM
Looking for a Reverse Offset Pin so I can attach a Colt upper to a CMMG lower.
Basically it allows mounting a Colt Upper Receiver with large pin holes to a mil. spec. (small hole) push pin type Receiver.

If anyone has one for sale I'm interested.
