Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on April 25, 2024

If you are already using an H buffer and your rifle functions as intended, the Armaspec C Sound Mitigation Gen3 Buffer that I would recommend is the H (3.8 oz) option, model MPN:ARM258-H.

Which one would you recommend for a 223/556 16 inch as a upgrade?

Expert Answer

Answered by Ethan, Gear Expert, from IL, United States, on August 02, 2023

I would recommend the Carbine Gen 3 Armaspec Sound Mitigation Buffer model (MPN:ARM258-C). With a weight of 3.3oz it will retain optimal functionality and reliability while providing a smoother, and quieter operation. If you are running suppressed, then the H Gen 3 model would be my recommendation.
