A 74mm side rail section for HK's HKey accessory-mounting system — HK's own interface used on modern HK handguards. Bolts onto an HKey slot to add a short Picatinny rail section wherever you need to mount a light, laser or other rail-mounted accessory.
Why you'll love it
-
74mm length, enough for most lights and lasers without adding unnecessary bulk
