Straight-pull builds: these sights clamp to any MIL-STD-1913 Picatinny rail, so they fit UK straight-pull and rimfire AR rifles with a flat-top upper or railed gas block. Read our straight-pull AR-15 parts guide for what fits and what does not.

Polymer or steel? Read our comparison of the Magpul MBUS 3 vs MBUS Pro — weight, durability, co-witness and price.

Shooting CSR? Iron-sight classes are part of Civilian Service Rifle, so backup sights earn their place. Read our CSR kit guide for a straight-pull AR-15 — stock, sling and sights for service rifle practices.
