Picked this, along with a lo-pro handguard, to convert a Bushmaster .223 into a Grendel. Order/ship time was reasonable. After getting on paper, it took four shots to get zero, and shots 5-8 went into .460 inch. 3 of the 4 shots were touching. Excitement caused me to put shots 5&6 out of the cluster, but it still came to a 6 shot group @ .699. Really considering a pistol build with Atheris barrel, BCG, and another handguard. Great product, and accurate as advertised. Posted 2/4/21

Beautiful craftsmanship. Locked up was smooth and tight. Can’t wait to reload some freedom pills and go break ‘er in!!
