I’ve recently built a Rebel-9. It runs beautifully and made me wonder, “why not other calibers?” There are many 9mm PCCs designs currently and I wanted to spice things up and give a go at a DIY bolt for a different pistol round. My thought is to scale the size and weight of the bolt to appropriately accommodate said round (5.7, 10mm, 45acp) with SCS bolt face. Would use AR Barrel. Let me know if there are any ideas or suggestions. Also let me know if there is a reason this hasn’t been done before and am biting off more than I can chew lol. Thanks!
The decker is a fully diy in .380acp and the 3dp90 is a a diy 5.7, so it for sure would work, the only thing in the 3dp90 that’s usually not diy is the barrel, but they do include the blueprints in case you got a barrel blank and a lathe. I dunno about .45 since its such a bigger round, the bolt would have to be heavier and the upper stronger, but you can for sure do it
