Same as sfx/elite combat - Canik Extended Mag Releases

I have been shooting competitions for years with an SFX. When I went to the Mete SFX, I wanted the extended release. This is my second order here for the same item. As the other review states, it was a bear to install. Find a flat screwdriver that just fits the channel and use that to hold the spring in place. The second one I got from them came in an open package and the tool and 2 of the extensions were missing. Fortunately, the one I wanted was attached. I really didn't want to wait for OP's painfully slow shipping for a replacement. OEM Canik part, so fit is perfect.
