Since I finished my precision build a couple months ago I finally got to get it sited in and did some shooting at the Armory shoot last weekend. I am really impressed with my Block Hole Barrel. I never thought I would be able to shoot like this. It is addicting for sure. I don't think I would have the results I did if it wasn't for the barrel and the Geissele trigger I installed in it. Some of these were bought match ammo but the best group was the rounds Ray brought and loaded himself. All are 5 shot groups.
