Q
Mattg, guest, from WY, United States, asked on December 30, 2023

Will I still need a spring or is this a replacement for the buffer and spring?

Manufacturer Answer
A
Answered by KynSHOT, Manufacturer from NY, United States, on December 02, 2024

Yes, you will still need a buffer spring when using a KynSHOT Buffer. The KynSHOT buffer replaces the standard buffer system or any other buffer system on the market. The buffer can be used with all Mil-Spec buffer springs on the market.

Q
Nonetheless, guest, from FL, United States, asked on April 02, 2022

Would this be a good option for an AR in 7.62x39??

Expert Answer
A
Answered by Ethan, Gear Expert, from IL, United States, on April 26, 2022

No. This KynSHOT AR-10 7.62mm/.308 Recoil Buffer is designed for calibers based off the .308 cartridge. KynShot recommends using the KynSHOT AR-15 .223/5.56mm Carbine Recoil Buffer (designed for carbine length buffer tubes) or the KynSHOT AR-15 .223/5.56mm Buffer for Fixed Stock (if you have a rifle length buffer tube). You can find both buffers in the links below:
