[ARCHIVED THREAD] - twist

Posted: 11/29/2016 11:53:08 PM EDT

I am planning an AR pistol build. It will be a 5.56, and can not find information about twist rates on the shorter barrels. I plan a 10.5 inch barrel, will twist rates to stabilize bullets compare to a 16 inch? I currently have a 16 inch rifle with a 1:9 and it likes 62gr a little better than 55gr. Can I expect similar out of the shorter barrel?

thanks
