"Overall, i gitve this a 4/5. All the parts work very well, and i recommend you watch ideos on youtube before trying to install by yourself (unless you take it in to a sotre and have them convert it for you). The installation was easier that way and everything was fine. Very poleased with this, but there is one issue: the bolt catch piece does not catch when the mag is empty. Unlike the AWSS version, this piece comes shave off a bit more so that it never meets with the bolt, so there will be dry firing issues and you might waste some gas.

-Easy installation, once you know what your diong
-All the parts (exept one) work after install

-Bolt catch does not "catch"
