This amazing work was done by the father of Mxpatriot51 off AR15.com
Magazine drops via a working magazine release, trigger moves and resets via a spring, slide cycles, sights are “dotted”, grip is profiled, etc.
Trigger does move, and returns, on a spring.
He says it took between 150 – 250 hours until he got it how he wanted.
Unfortunately at this point he is not making them to sell.
