Looking good. I haven't started yet on mine. Will do the upper first so I can bed the barrel and let it set while I do the lower. Give it a few days to cure then put the upper and lower together so I can mount and zero optics and get ready for load development.

Bedding the barrel on an ar15?
Yup, I didn't know that was a thing either until watched a great video on YouTube. Pretty cool actually.

Yes, I use loctite 620 to bed it. Variances in parts can allow for slight gaps and play between barrel and receivers, some tighter than others and even needing thermal fitting. I took one of my plinker 18" ARs and used it as an experiment since the best I could get from it was usually around 1.3" with handloads. There was some play between the barrel and receiver before tightening the barrel nut. I believe that Lil gap causes the barrel to shift slightly when firing. So I used loctite 620 to fill the gap, let it sit for a few days, then took it back to shoot. Groups went from 1.3"-2" size down to around the .65-.7" range with some being smaller. This was with a cheap barrel since it was a plinker. So I'm sold that filling the gap between the barrel and receiver actually does work. Will be doing it on all future builds and the others I already have.

Did you lap the upper?
