Paired with a sprinco red spring it works great - Blitzkrieg Components AR 9mm Heavy Damped Buffer

I replaced the Spikes AR9 buffer and stainless spring I have had in my New Frontier G9 gen2 8” pistol build for the last 4 years. It made a pretty noticeable reduction in recoil keeping the barrel more on target with repeated shots and reduced the buffer spring noise. It was smooth and shot well before but the new set up is just so much quieter and softer shooting.
