Very nice job!!!
I havent measured the step down side to side. Is .063 what the original stubs had for step down? I havent measured the step down on a stub. I do know that the bolt carrier rides VERY nicely in these receivers. No up and down slop like in unstepped receivers.ammoboy2 said:The step-downs add a nice touch to a flat. Do you get an even amount of step-down side to side, about 0.063?
You might want to remove a bit of material on the right side just after the trunnion cut from the nominal AK builder rail width dimension to an 0.145 width for about half an inch to allow brass ejection clearance. The Maadis and NDS-1 have the clearance.
I need some stamps.
I havent measured a milled receivers top rails either. I'm sure someone here can enlighten us? Yes the step down was to get that thickness back for I think a few reasons. It strengthens the rails, during forming it squares up the bends, and to keep the carrier from riding up and over the sear instead of staying down and tripping it. Of course we are not worried about tripping the sear. I like the step down because it squares the bends, adds strength to the rails, reduces carrier slop and because it just plain looks way better!ammoboy2 said:The 0.063 inches is equivalent to 1.6mm. I have never measured a milled receiver to verify but 1.6mm is what I thought the rail thickness for the AK. The step-downs are of course the designers' method to approximate the thickness of the orginal design in sheet metal.
I thought making the ejection clearance cut easier prior to lower rail and/or trunnion installation.
Your welcome to come use it. I wont let anyone borrow it but ... I'll let you use it with me watching to make sure you dont break my $300 jig. :wink:Kayenne said:Damn that's sexy :shock: I might have to borrow that jig one day LOL
