Tokyo Marui Low 20mm Picatinny Rail Mount for SMG-5/G3

If you need an optic on your SMG-5 or G3 setup, this will do the trick! The Tokyo Marui Low 20mm Picatinny Rail Mount for SMG-5/G3 is made from alloy, providing a 20mm Picatinny rail on the top, ready for your choice of red dot sight or scope. This mount affixes to the HK claw lugs present on SMG-5, G3, HK33/53 and MC51 receivers and should fit most options on the market, though ideally this is paired with a Tokyo Marui-branded platform. If you want a red dot sight or scope on your SMG-5 or G3, add this, and you'll be set!
