The American Defense Delta Cantilever Scope Mount, 34mm 1.7″ (brand part no. AD-DELTA-C-M-34-STD) puts high-power glass onto a flattop AR-15 with a one-piece cantilever design that pushes the scope forward for correct eye relief without crowding the charging handle. American Defense Mfg machines this 34mm-tube version at a 1.7″ height, giving shooters running a large-tube precision scope a mount solid enough to hold zero through hard recoil.
