Poor match for Ruger AR 556 free-float 2/6/2023
Had to crank the adjustable front sight post all the way down and move the front sight almost half-way up the picatinny rail of the free-float handguard to get the sights on target. The back sight was the matching AR 556 sight bought at the same time from the Ruger accessories website. My Ruger AR 556 free-float is new in box with no modifications. Had the same problem with off the rack Magpul sights. Thought these would be a better fit since they are advertised as AR 556 sights on the Ruger accessories sight.
