The 30mm ROF-SAR is a drop-in upgrade for 30mm optics. The ROF-SAR adds a mounting point for an AIMPOINT Micro (T1-T2-CompM5) to provide for quick transition to a non-magnified optic for close-range target engagement. The ROF-SAR allows for user to orient the Micro optic at their desired orientation around the magnified optic.Features :Machined from billet 7075-T6 aluminumMIL-STD, Type III, hardcoat anodized41 gramsMade in USA
