The RB5000 KynSHOT

Recoil Buffer is designed to fit AR-15 carbines with a collapsible stock. Made using 17-4 stainless steel, the KynSHOT RB5000 Recoil Buffer is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the United States Armed Forces. This buffer has patented damping technology to absorb the shock of impact from the bolt carrier’s rearward motion and prevent bolt bounce as a new cartridge is chambered. The KynSHOT RB5000 Recoil Buffer reduces felt recoil by 20-30%, while largely eliminating muzzle flip.The improvement in weapon accuracy – specifically second and third shot accuracy- is large as shooters report that their time to reacquire a target decreases, and in many cases never leaves their scope sights.

SPECIFICATIONS

  • Weight 4.2 Ounces
  • Length when compressed 3.25”
  • Designed for .223/5.56mm AR15 Carbines
  • DO NOT USE IN 9mm AR-15s. For 9mm AR15s use KynSHOT P/N RB5007, RB5015HD, or RB5020SS. See Selection Matrix for proper buffer choice.
  • Mil-Spec Hydraulic Fluids and Seals- Ambient operating temp certified for -30F - +150F
  • High strength 17-4 Stainless Steel construction throughout the unit making it virtually impervious to corrosion.
  • Can be used with a wide range of AR-15 calibers to include .450 Bushmaster, 7.62x39, 6.8 SPC, 6.5 Grendel, 7.62x40 Wilson, .204, .350 Legend, etc.

The KynSHOT RB5000L Hydraulic Recoil Buffer is optimized for use with light loads, including subsonic ammunition and .300 BLK. The RB5000L has seen heavy use with civilian competition shooters, law enforcement personnel, and the United Sates Armed Forces. 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. This model is made lighter and requires less force to cycle than the standard AR-15 KynSHOT Buffer. This is intended for soft cycling or under gassed guns that will not lock back on the last round with the standard carbine hydraulic buffer or heavier buffers. .300 BLK guns running exclusively supersonic ammo may be fine with a standard hydraulic buffer if the bolt cycles firmly and has proper ejection placement.

SPECIFICATIONS

  • Weight 4.0 Ounces
  • Length when compressed 3.25”
  • Designed for 5.56mm/.223 cal. AR-15 with a collapsible stock
  • DO NOT USE IN 9mm AR-15s. For 9mm AR-15s use KynSHOT P/N RB5007, RB5015HD or RB5020SS. See Selection matrix for porper buffer choice.

The KynSHOT RB5001 Recoil Buffer is designed for Fixed Stock AR-15s. This is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the United States Armed Forces.  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. The RB5001 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.

SPECIFICATIONS

  • Weight: 8.3 Ounces.
  • Length when Compressed: 5 7/8".
  • Mil-Spec Hydraulic Fluids and Seals - Ambient operating temp certified for -30F - +150F
  • DO NOT USE IN 9mm AR-15s. For 9mm AR15s use KynSHOT P/N RB5007, RB5015HD, or RB2020SS. See Selection Matrix for proper buffer choice.
  • High strength 17-4 Stainless Steel construction throughout the unit, making it virtually impervious to corrosion.
  • Designed for .233/5.56 mm cal. type AR-15 rifles with a fixed stock, and can be used with other popular AR-15 calibers as well such as .300 BLACKOUT, 6.8 SPC, 6.5 Grendel, .204, etc. 
  • This buffer can be used with heavier calibers such as the 458 SOCOM, 450 Bushmaster, 6.5 Grendel, etc. Works great with these calibers due to heavier weight and dampening effects.

The KynSHOT RB5004 “Shorty” Recoil Buffer is designed for AR-10 carbines with a collapsible stock and an AR-15 length (7.0") buffer tube which is common on many AR-10 applications. The RB5004 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.

SPECIFICATIONS

  • Weight: 3.8 Ounces.
  • Length when Compressed: 2.5" and replaces buffers that are 2.5” long.
  • Mil-Spec Hydraulic Fluids and Seals - Ambient operating temp certified for -30F - +150F
  • DO NOT USE IN 9mm AR-15s. For 9mm AR15s use KynSHOT P/N RB5007, RB5015HD or RB5020SS. See Selection Matrix for proper buffer choice.
  • Designed for 7.62mm/.308 cal. AR style rifles with an M4 length buffer tube (which is 7” deep, and ¾” shorter than an Armalite AR-10 collapsible stock tube). This is a common factory stock arrangement on many factory .308 rifles such as DPMS, CMMG and many others. The best reference is that it replaces factory buffers that are 2.5" in length.
  • Also works
  • well with other calibers based on the .308 case such as the .338 Federal, .260 Remington and .243 Winchester if they have the M4 buffer tube. If you buy an aftermarket AR-15/M4 collapsible stock tube for your .308 AR, this is the buffer you will need. The Magpul UBR stock also uses an AR-15 carbine length stock tube and would also require this buffer if used on a .308 rifle.

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.

  • Designed for 7.62mm/.308 cal. AR-10 type rifles with an AR-10 length collapsible stock buffer tube which is 7 3/4" long on the inside (AR-15 collapsible buffer tubes are 7" on the inside). The best way to confirm is to measure the length of the buffer that came with the rifle from the factory. 

The KynSHOT RB5006 Recoil Buffer is designed to fit AR10/.308 rifles with a fixed stock. Made using 17-4 stainless steel, the KynSHOT RB5006 Recoil Buffer is a proven system that has seen heavy use with civilian competition shooters, law enforcement personnel and the United States Armed Forces.

    Kynshot RB5000

    Posted by Thomas Wright on 28th Jan 2021

    I rated this Kynshot at a four, rather than five, because I have the Kynshot RB5005 for the 308 and the recoil dampering was SO dramatic, that I expected the same out of the RB5000 for my Grendel. It definitely dampered recoil, and was absolutely worth it. I would say, get them both.

    Second one I’ve purchased. Bought this one for a friend and we both like them. Reduces recoil and improves accuracy of quick follow up shots.

    RB5000

    Posted by Tim on 3rd Aug 2020

    Yes you will notice immediately how much smoother your rifle feels. Not by a great deal but maybe by 20-30% if that makes sense. When I engage a target up close and just decide to dump rounds in it I can see my shot group tighten. I’m not disappointed with this purchase.

    Kynshot recoil dampener

    Posted by Stephen Blayne Smith on 17th Feb 2019

    This thing is awesome! It makes a 223 round feel like 22LR. Can’t wait to see what it’s like with the 6.5 Grendel I’m putting together. It’s super sweet.

    Kynshot Hydraulic recoil buffer

    Posted by PADuck on 17th Nov 2018

    The "traditional" spring-based recoil damper design of the AR leaves much to be desired. I have been looking for a good price on a quality hydraulic damper this fits the bill in my current 10.5" 300 AAC Blackout build. I have only fired a few rounds, recoil is reduced- on a round it is already low recoil. Quality appears high on this item. This was a good purchase.

    Really works well in reducing recoil and making the rifle work more reliably.
