[QUOTE="GlockPride, post: 3634150, member: 12153"] You mean like me? I bought one of their 11.5” carry handle 5.56 AR pistols in June. Never even thought to look at twist rate. 25 yard “grouping” looked like buckshot pattern. Couldn’t figure out why XM193 wasn’t grouping at all. Looked down at the barrel and then slapped my forehead when I saw 1:7. Now searching up a 1:8 or 1:9. ETA: I think in the shorter barrels the 1:7 is used more predominantly because it’s assumed that you would use a heavier bullet since the shorter barrel will not deliver the speed needed for 55 grainers to function at their max capabilities. I’ve found a few 1:8, and only maybe 1-2 1:9 twists in 11.5”. Anyone know anything about Rosco barrels? [/QUOTE]
