This Quick Detach will allow you to equip multiple guns with your Air Rig. Just put one of these on each of your PR-15s and you can switch between them with the release and coupling of your QD attachments.

Please note: This quick disconnect is for the non-MINI Quick Disconnect Couplers.  You will find this on almost all our original Air Rigs. 

The new mini connectors take a different coupler.  Here is a link to the mini coupler set: Click Here
