A bit Expensive but worth it. The original 2011 magazines have current issues that this tuning helps to erase
Should be required
Well made DVD and tools are what's required to tune your mags. Easy to understand and with good filming.
Awesome
I’ve never tuned my mags before but this kit and enclosed video made it easy.
Works great
I tuned up 5 mags and so far 4 of them are working great. The other one gets hung up somewhere in the middle. Not sure if it's the mag tube or something else bit using this kit, i cant seem to solve the issue.
Very good!
Very good tool for shooters.
