Which ones fit your barrel and host?
See all 4 in the Builder- The assembly works by removing your existing piston cap and piston and replacing them with the 3 Lug nose receiver, utilizing the existing spring. Designed to be installed and removed with a 1 1/4 12 point socket.
- High-quality stainless steel, black finish.
- Designed to fit both Seafire 9 and 45 models, and to accept common HK 3 Lug hosts. This product will function with most HK 3 Lug adapters.
- This assembly, if used with a non-fixed barrel pistol, will NOT cycle — the original Nielsen device set-up must be used in order to cycle.
