NoKick Combo - KynSHOT RB5005 Hydraulic Buffer / JP Tuned & Polished Buffer Spring
For Hard Running AR-15 with Collapsible Stock

This is the softest running buffer combination available for an AR-15 of any caliber with a collapsible stock that runs hard. In this combo deal you get the KynSHOT KYN-RB5005 3.25" AR-10 carbine buffer with a JP AR-15 carbine buffer spring. The RB5005 buffer is the same length as the AR-15 RB5000 buffer, but is heavier at 5.5 ounces and has hydraulics tuned for heavier levels of recoil. It has proven to be an outstanding buffer for hard running AR-15 systems. Examples include many short barreled 5.56 rifles with pistol gas systems, suppressed SBRs, many piston systems including the PWS piston guns and heavier calibers like the .50 Beo or .458 SOCOM. This heavier model KynSHOT hydraulic buffer has proven to be the sweet spot for these harder running AR type rifles.

The buffer acts as a shock absorber for your bolt carrier noticeably reducing recoil impulse and speeding shot recovery for faster follow up shots. The buffer also makes chambering smoother and more consistent resulting in tighter shot groups and improved feeding reliability. The JP Buffer Spring is ground and polished on the outer edge making operation as smooth and quiet as possible. This spring noticeably reduces spring noise whether shooting suppressed or unsuppressed. Together, these parts provide a soft recoiling system that is smooth, quiet and fast. We have tried all the buffer combinations out there and have helped thousands of customers with their builds and can tell you, this will give you the most significant improvement in performance. Satisfaction guaranteed.

This combo is intended for AR-15 framed guns so it includes an AR-15 carbine buffer spring. If you have a .308/7.62 AR-10 framed gun, you would need to combine a KynSHOT AR-10 buffer with an AR-10 strength buffer spring.

5 of 5 LWRC M6 IC-E 5.56 November 25, 2020
Reviewer: Chandler~ from Smithfield, VA United States  
My LWRC was ejecting reliably at 1300 and after installing this kit my ejecting was at 1530-1600 reliably. Excellent product and works great! Definitely tuned my rifle up! Can’t go wrong! If you don’t have a piston or SBR I wouldn’t go with the heavy combo. Thanks for all the help Brian!

5 of 5 Perfect for 6.8, 6.5 Grendel, and PWS piston SBR January 22, 2018
Reviewer: Kyle Land from Royse City, TX United States  
I use these in all my harder hitting caliber builds, including the .308 versions, both carbine and rifle length. They work INCREDIBLY!  I have built numerous rifles and suggested these to their future owners and they have absolutely loved how soft shooting and smooth their rifles are.  You are not gonna feel much of a difference with a 556 unless you run it in an SBR or piston system where the bolt is slamming backwards. This helps smooth that out. For your 6.8 and 6.5 Grendel loads, this makes those rounds shoot very soft. Excellent product, 1000s of rounds and zero failures out of multiple rifles. NoKick knows their stuff! Trust them!
