loose noose
Member
Has anyone ever heard of the above quad rail designed for a M-4 flat top AR-15, so that the front sight/gas block doesn't have to be removed, just loosened and the quad rail will clamp on, in place of the standard forearm, and then the front sight/gas block replaced. The guy I do gunsmithing for insisted I do such an operation on a Stag Arms, AR-15 M-4 for a customer.
I tried to explain to him the front sight would have to be removed along with the flash suppressor, and a new gas block would have to be installed, as well as the appropriate barrel nut. I'm totally unaware of a 2 piece quad rail on the market, as I built quite a few free floating AR-15's with the quad rail. However I could be wrong it's happened before.
I'm looking for some feedback in this matter, as he is adamant that it can be done. Note he wants to have me to install a scope, in front of the rear sight, and he insists I leave the rear sight (GM Gear) in place. Any help in this matter will be greatly appreciated.
