Would this be the one to purchase for a AR10 308 POF rouge AI Answer

This buffer is designed for AR-10 pattern rifles with a standard collapsible stock buffer tube that has an internal length of at least 7.75 inches, so it would work on a POF Rogue only if that rifle uses a tube of that length; be sure to measure the tube before purchasing.

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 littl...

Hydraulic Kynshot Buffer by ShtBrd, Verified Owner, March 30, 2018
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 ...

Amazing upgrade. by MKDV, Verified Owner, 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, 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 tha...

Kynshot in my AR10 by Phil, 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.

Not for Smith and Wesson M&P10 by Mkern, Verified Owner, November 24, 2022
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 emp...

Product Info for KynSHOT AR-10 7.62mm/.308 Recoil Buffer w/ Standard Collapsible Stock

The KynSHOT RB5005 Recoil Buffer is designed for AR-10 carbines with a collapsible stock that use the standard AR-10 length tubes that are 7.75" deep on the inside. The RB5005 reduces felt recoil 20-30%, while largely eliminating muzzle flip. The improvement in weapon accuracy - specifically second and third shot accuracy - is even more noticeable as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights. This buffer has patented damping technology to absorb the shock of impact from the bolt carrier's rearward motion and to prevent bolt bounce as a new cartridge is chambered.image

"This buffer requires a buffer tube with an internal length of at least 7.75 inches. As many tubes are only 7 inches in length, this must be checked before installation."
