Our two round holder for 22LR is CNC Machined from acetal. Engineered to hold two rounds in any M-LOK compatible slot on your rifles stock or chassis. Sized o-rings hold the rounds in alignment with the pockets to insure the healed bullets do not get knocked out of concentricity with the casing. Plenty of holding force is applied by the o-rings to insure the rounds are never lost or dropped from jarring. A deliberate removal by the shooter is required to release the rounds from the holder. This accessory has one off center M-Lok attachment. The offset holes allow more freedom in mounting locations on different firearms.
