The Geissele Super Modular Rail MK16, 15-Inch M-LOK, Black (brand part no. 05-792B) delivers unmatched performance for demanding shooters through Geissele’s updated barrel nut design, which mounts to your AR-15 upper for both easy installation and superior rigidity. Anti-rotation tabs and set-screws keep the rail from rotating even under extreme use, while an M1913 Picatinny rail on top and M-LOK slots on every quadrant ensure you can mount whatever your build needs. The SMR MK16 is precision machined from 7000 Series Aluminum for its strength, rigidity, and light weight, then finished in a durable Type-3 Hardcoat anodizing. At 15 inches, it covers a full rifle-length build with plenty of room for lights, optics, and other accessories.
