Lie this adapter
The sling adapter is great and very easy to install!
Simply pull down on the adjustment lever of either a four or six position stock until the pin is disengaged enough to slide the plastic portion of the stock completely off to the rear. Then slide on the adapter, tighten one screw and install the stock in the reverse order and your done in about two minutes. No removal of the buffer tube or special tools needed
