[QUOTE="CaptnC, post: 1476751, member: 101755"] I would go 20" for the extra velocity. I have both 18" and 20" both shoot great but I run the exact same ammo out of both and easily see nearly 100fps gain with the longer barrel. I also agree with Mud...some of the less expensive uppers out there have issues. Short throat is very common, so is 4 to 5 MOA at 100yds. I got super lucky buy two super cheap barrels that both easily shoot MOA out to 400yds. I'm not going to suggest you might have the same luck. I converted two AR's I already had in the safe...both had not seen daylight in years. One 5.56 bull barrel...shot great, but I dis-like the chambering badly! The other 7.62X39...it had seen some action on WT deer, Blackbuck Antelope and hogs. But I never trusted the accuracy of it so I limited my range. I will have one of the Grendel's with me nearly every trip into the deer woods this fall. That's how impressed I am with this cartridge! [/QUOTE]
