Re: what quad rail for a stag arms 8L?
I would call Stag and see if the piston system they are using is an Adam Arms or one that they made. If I am not mistaken Troy Industries makes a free float that may have enough room for the piston to operate, also try Vltor. Adam Arms has a website of you google it, on there is a list of compaines that make quad rails that will work.I hope this helps
