Right. Length really doesn't contribute to accuracy in any significant way. Stiffness, uniformity, chambering, proper twist rates -- these contribute to accuracy. Perhaps non-intuitively, shorter barrels can result in increased accuracy (to a point).TheDude wrote:A longer barrel does not make a gun more accurate. It makes it easier to shoot accurately if using iron sights because of the longer sight radius but thats it. With red dot that doesn't matter. You will lose some velocity with a shorter barrel.Richardc wrote:OldCannon wrote:If you're just a plinker, 1:9 is perfectly fine. If you need to drop steel (or, um, other heavy targets) at 400-500m, you're gonna want to shoot 77gr heavies with a 1:7 twist.
Honestly, 1:9 is perfectly fine for 90% of the AR owners.Also if your not going to be kicking in doors get a 20in upper 16s are cute and all tacticool, but they are loud and the loss in accuracy is not worth it. I have never had anyone out gun me with their 16 when I'm running my 20.
