Bolt Carrier, carrier with Charging handle. Charging handle was remade and heat treated after I bent the one in the picture.

Lower. EP ARmory 80%., with buffer extension removed and pocket milled for attaching to upper. This lower is way out of spec and had to shim the Bolt hold open and the selector. Would not recommend for anything other than a .22 AR.

And this is why some people should not be allowed to buy a drill press :shock:

Not many people know this, but the reason gds is not capitalized is that they are not the OP’s initials. They represent what his parents were constantly yelling at him. “Gosh darn son, is everything a gun to you?” In public all it took was a sideways glance and a mumbled gds, and the OP would immediately bite the barrel off the pancake he had cleverly chewed to the shape of a glock. :P

All kidding aside, what can be produced with a few simple tools and a deep working knowledge of firearms always amazes me. The number of people who seem to have trouble assembling a functioning AR that will reliably shoot, should give a clue to what gds has done.

To dump a mixed mag and not miss a beat is more difficult than it seems. To do it quietly and accurately is another level of smithing. Yes, that was a form 1 suppressor also.

Another job well done MR. Stonishnakavzi.

It would have been a 1911 back then. Not a glock. :P
