Most Helpful Positive Review Hydraulic Kynshot Buffer
I installed this buffer for use with a piston driven AR-15 upper. I was skeptical when I purchased this buffer but it only took one mag to feel what this buffer can do. It does an amazing job at smoothing the recoil impulse. Keeping the sights on target became a breeze in rapid fire. I do not ha...

Most Helpful Negative Review Not for Smith and Wesson M&P10
I tried this RB5005 in my 308 mp10 with a 18" barrel. I found that this buffer would not operate consistently and would prevent the bolt from properly feeding rounds. Basically short stoked. It would also not consistently lock the bolt back on an empty mag. Lastly I reached out to Kynshot and they n...

Works perfectly

by Husker4Life1976, Verified Owner from TN, United States Written on March 15, 2026

Smooth, effective, and easy to install.

by Disobey, Verified Owner from FL, United States Written on October 2, 2025
Smooth, effective, and easy to install. Tames muzzle rise on my AR-10. Faster follow-ups and a noticeably more comfortable ride. Highly recommended.

Kynshot in my AR10

by Phil, from UT, United States Written on January 26, 2024
This device showed Zero recoil reduction and caused my brass to get severe dents on the back from the ejection pins and fails to lock my bolt back on empty mag.
Would recommend: No

Amazing upgrade.

by MKDV, Verified Owner from FL, United States Written on March 4, 2022
Super easy to install, direct replacement. Honestly, I was little upset about recoil of my AR10 .308, but after I install this buffer to my rifle, it’s became from “meat tenderizer”to “Hello Kitty” instantly. Absolutely recommended.

Not for AR10 308 DPMS Carbine

by Kevin, Verified Owner from MO, United States Written on March 2, 2022
Not for AR10 308 DPMS Carbine Rifles. It does soften the recoil, but it’s too heavy, and the rifle will not cycle. During cycle, it will eject the brass, then jam the new round. I contacted Opticsplanet, and they referred me to the correct buffer that I needed.
Pros:
  • Less recoil
Cons:
  • Too heavy to cycle
Would recommend: No

Very effective!!

by Dragonw4g, from WA, United States Written on October 21, 2020
I have, lets just say more than one AR. I have 2 of these. I ran this with a flatwire Spring VS. An Armaspec sound mitigation buffer system VS. Old school buffer and spring. Standard Buffer was your standard .308 Bump. The Armaspec device was a little bump soaked into a push. The Kynshot eliminated almost all the bump and made it more of an equaled out press on the shoulder. I let other .308 shooters try it out and they were extremely suprised. (Note, be sure of the length of your buffer and tube. Install with same length buffer already installed. 3.25 inch in AR-10 style carbine tubes. 2.50 inch in .308 with M4/ AR-15 carbine tubes.
