    Mag Extension Fit great

    These are top quality items. I bought some 3D printed units that lasted about 3 months before breaking. At $20 each I wasted $40. The Zermatt units are built like a tank. My only complaint is it is an expensive pill to swallow on fixed income, but they are the best.

    Great extension

    These extensions are well machined and a piece or beauty. The install is a little crazy keeping the spring in place, but it was simple 5 -10 min install with the spring sliding out of place a couple of times.
