Very accurate - Lothar Walther AR10 Rifle Barrel

I posted a previous review on this barrel and now i have an update. I contacted Lothar Walther in Georgia and they sent me a return label to return my barrel even after 1.5 years after my initial purchase date(was busy doing other builds) and replaced it with a brand new barrel. I installed the new barrel and took all of my previous loads that the original barrel would not group with to try. This new barrels shots lights out with everything i tested except Wolf steel case ammo. I shot 3 shot groups to conserve ammo and get a general reference. Federal Gold Medal Match 175 BTHP was the best at slightly under half an inch followed by IMI 175 BTHP slightly over .5 inches , and finally Hornady ELD Match 168 just under .75 inch group. I have more to try since that test but i am very pleased. The barrel holds groups well even when warm and the finish was excellent. I had no problems with the gas block or gas port being under sized. I used the Superlative Arms. 875 adjustable gas block with set screw along with the Aero Precision enhanced 15" handguard with plenty of clearance inside. Great customer service and they stand behind their products.
