building custom AR style single shot

[22_boomer]

Thanks for sharing that info. It's kind of the same reason I did the manual AR setup but mine was to shoot rounds that wouldn't operate a gas system due to low loads of Unique. I just got a second Grendel barrel and was thinking of maybe doing a manual AR with the 24" barrel I originally had but decided shooting it with the gas system was just too much fun right now so I'll stick with the manual AR and .223 rounds. Right now I'm trying to see what twist rate shoots the light load stuff the best. I started with a 1:7 twist and it actually shot darn good but I'm going to run a 1:9 twist next or maybe a 1:12.

What range or combination of ranges are you shooting at and what bullets are you using in your setup?
