    Question about stamped feed ramp

    Good morning.

    I'm getting the stuff together to try to make a complete receiver, dedicated for a pistol build. I already have a semi grip stick and semi bolt/striker setup from my carbine so I thought it would be neat to have a second receiver, dedicated as a pistol, and can just swap the SA guts out between them.

    I can see there would be some technical difficulties with trying to salvage the stamped feed ramp potion of the cut SMG scrap receiver pieces, but are there any legal issues with doing it?

    Ideally, I'd be using a SMG front stub and a repair section, so a take-off used SMG barrel would be way to go as well. I read the feed ramp page, it mentioned problems feeding HP's with the original style, but I'd be running cheap FMJ anyways.

    Is the blocking bar in the receiver enough to be "kosher" for a complete receiver? I'd think I could ream out the bushing for the grip assembly to 9mm without a problem. But is the "restrictor ring" thing required by law?

    The blocking bar is the thing that is required. You do not need the restrictor ring. The stamped feed ramp should work if you are not using hollow points or flat point 147gr bullets. Good luck with your build.

    Awesome, thank you.

    I’m hoping I can position it and test with just a couple tacks holding it in place. Worst case scenario I wind up waiting for US made feed ramps to come back around.
