The 1-Piece COP Scope Rail Forever Ends The Problem Of Scope Mis-alignment.
Just when you think there can’t possibly be any more versions of the AR-style rifle someone comes up with a new idea. We’ve all seen AR uppers with round handguards (comfortable to handle and shoot) and with 4-way accessory rails (handy for hanging accessories on the rifle, but hard on the hands).
Of course if you don’t mind the cost, you can always have a choice with completely assembled uppers in both styles, as uppers can be interchanged in seconds.
ArmaLite’s new idea is an upper, which allows either handguard style on one assembly. The upper receiver and the top of the handguard are 1-piece forged alloy. An integral Picatinny-style sight rail runs from the back of the receiver to the front of the handguard.
