I used a plinker jig to bend the flat
Heat treated the rails and the holes with a map torch until the receiver wouldn't take a magnet, and quenched, then re-heated the recvr. until it started to "blue"
put the rails on with a modified spot welder.
i decided not to put any flashider on it at all yet, looking for a good deal on a krink F/H
and the barrel length is standard amd65 length (11-11.5"?)
I also cut the front sight off of its base, leaving the muzzel device stud in place, and fitted the sight to the gas block and filled in the gaps to make it look like a krink FSB was on there. i am not going to lie, my pistol is friggin UGLY, but sweet at the same time. kinda like a kid who only his mother could love his face, ya know? if ya want, i will post a pic of it. LMK.
