this rail is great very easy to install and looks great on any gun (g4-a1 for proof) very solid and the blackside and quick silver madbull barrel extentions fit perfectly in it, my CQB front end is this, a stubby killer outer barrel, and a blackside extention. this works great for cqb and looks awsome.
easy to install
hard to scratch
