Bear Creek Arsenal Complete Uppers

[1Shot]

I don't have any JB but a buddie does so I might borrow some and give it a try. My barrel is just plain stainless with conventional rifling. Yes there is a big difference felt when pushing a patch down the BCA compared to the OdenWorks. Oden is like greased glass and BCA is like somebody mixed sand in the grease. You should not have to shoot 50 to 100 rounds in any barrel to get it to group.
