RCM HK21 Trunnion
When RCM set out to make a replacement trunnion for the venerable HK21, they started the process by putting a factory unit through rigorous destructive metal testing. The end-product: a US-made trunnion blending the proper metalurgy and heat treatment to garauntee years of belt-fed fun.
Compatible With:
- HK21 (Including FMP variant)
- HK11
- NOT compatible with HK21E’s or HK11A1’s due to the handle latch interface
