I have only built 1 AR rifle but I am wanting to build another. My first was a 9.5" 300aac that I'm not really expecting to shoot farther than about 100yds so I just bought parts and put them together. This time I would like to build a Grendel with somewhere between an 18" and 22" barrel. I would like to be able to use this rifle to shoot some of these little bitty groups I see some of you guys shooting so I started looking at tools to face the upper, AGBs, muzzle breaks, and just anything to make this future build smooth shooting and accurate. Then I started noticing on this site, guys talking about bedding the barrel to the upper receiver with blue loc-tite. What is the theory behind this? Does the barrel nut not hold the barrel in place well enough? How do you do this, just put some around the barrel extension before sliding it in the face of the receiver? I have also seen guys talking about bedding the gas block with blue loc-tite. Again, how do you do this, a few strings around the barrel being careful not to get any in the gas port? I can see where this may help seal off any gas leaks but does it help with accuracy? I have stayed in the Holiday Express but I guess I went to sleep to early.
