  The RB5007 is a specially engineered KynSHOT for the 9mm PCC application. Designed in cooperation with Blitzkrieg Components, LLC. to work in PCC builds with 3.5" - 16" barrels, either suppressed or unsuppressed and with all common 9mm loads. Compatible to Carbine Length Buffer Tubes Compatible to 9mm Standard Blowback Systems ** Use the SPRINCO 25004 9mm Extra Power Buffer Spring RED for optimal performance ** NOT compatibel to CMMG's 9mm Radial Delayed Blowback System, use RB5000HP for trouble-free operation! This buffer has proven itself in the harsh arena of PCC competition and is the choice of many of the top ranked shooters in the world. The KynSHOT uses patented hydraulic shock absorption technology to dampen the impact of the bolt at the rear of its travel and to dampen the forward impact of the buffer’s weight as it chambers the next round. Its weight and length have been optimized for the 9mm application so that it runs reliably, softens recoil, smooths out the action, and stops just behind the bolt catch. (ECCN Controlled). Compatible accessories see under this article, accessories. FAQ / Frequently Asked Questions What is the difference between RB5007 and RB5015HD? The RB5007 is our standard damped PCC buffer which is used for direct blowback PCC’s that have a barrel length of less than 8”. The RB5015HD is designed for all suppressed PCC’s or barrel lengths that range greater than 8”. The reason why we have two PCC buffers is because you add a suppressor or longer barrel to the PCC the bolt cycles much harder than shorter barrels. The RB5015HD is also a perfect choice for other PCC calibers such as the .40SW, .45ACP, and 10mm. The RB5015HD has enhanced damping than the RB5007.

  Our KynSHOT buffer weight, that was designed in cooperartion with Blitzkrieg Components, LLC., can be used with our PCC hydraulic buffers, and in certain cases, our AR hydraulic buffers to add mass in front of the buffer. Compatible accessories see under this article, accessories. The Spacer Weight also adds .75" in length to the buffer system, and adds 2.5 ounces of weight, which is designed for a close fit buffer tube while preventing tilting of the buffer during cycling. The weight has several functions: the additional mass further delays initial bolt movement and slows the bolt velocity, it helps to keep the buffer aligned in the buffer tube, and its additional length can be used to make a short stroke system if desired. BENEFITS  If you want to use this weight and have your bolt cycle the full distance and stop behind the bolt catch, then you need to use an AR-10/A5 length buffer tube since they are .75" longer on the inside. If you use this weight with our buffer in a typical AR-15 buffer tube it will create a short stroke system that stops forward of the bolt catch. Additional mass is very important in any PCC short stroke set up since the bolt doesn't have as much time to slow down. SPECIFICATIONS  Optimal set up - We believe that the optimal set up for most 8-16" barreled guns is to run this PCC Buffer weight in front of an RB5015HD buffer with a .308 carbine buffer spring in an AR10/A5 buffer tube for full bolt stroke. If your bolt has a weight pinned into the rear of it, we recommend leaving that in place to retain full mass of your bolt. We do have customers who like the short-stroke set up the best and everyone's perception is a bit unique, but it has been our experience that the full-stroke set up is the smoothest running and softest recoiling overall and you retain the use of your bolt catch. The weight is made of machined 17-4 Stainless Steel. Weight: 2.5 Oz / 70,87g MADE IN THE USA

  The RB5015HD is a specially engineered Heavy Damped KynSHOT for the 9MM PCC application. Designed in cooperation with Blitzkrieg Components, LLC. to work for 9MM applications with barrels 8” or greater, either suppressed or unsuppressed and with any type of ammo. Compatible to Carbine Length Buffer Tubes Compatible to 9mm Standard Blowback Systems ** Use the SPRINCO 25004 9mm Extra Power Buffer Spring RED for optimal performance ** NOT compatibel to CMMG's 9mm Radial Delayed Blowback System, use RB5000HP for trouble-free operation! The hydraulic fluid and seals are made to meet mil- spec requirements and have an ambient temperature operating range of -30F to +150F. The KynSHOT uses patented hydraulic shock absorption technology to dampen the impact of the bolt at the rear of its travel and to dampen the forward impact of the buffer’s weight as it chambers the next round. Its weight and length have been optimized for the 9MM application so that it runs reliably, softens recoil, smooths out the action, and stops just behind the bolt catch. (ECCN Controlled). Compatible accessories see under this article, accessories.  FAQ / Frequently Asked Questions What is the difference between RB5007 and RB5015HD? The RB5007 is our standard damped PCC buffer which is used for direct blowback PCC’s that have a barrel length of less than 8”. The RB5015HD is designed for all suppressed PCC’s or barrel lengths that range greater than 8”. The reason why we have two PCC buffers is because you add a suppressor or longer barrel to the PCC the bolt cycles much harder than shorter barrels. The RB5015HD is also a perfect choice for other PCC calibers such as the .40SW, .45ACP, and 10mm. The RB5015HD has enhanced damping than the RB5007.

Check your rifle with the Ejection Angle Chart  _____________________________________________________________________________________________________________________________________________________________________________________________ General Informations Why do we assign "COLORS" to our buffer springs? We have tens of thousands of buffer springs in various stages of enhancement or in inventory in our facility. This practice is beneficial to both you as the end user and for our employees to identify for quality control and fulfillment. We use Dykem® Opaque Metal Staining Dye to color code the springs, (not rattle can spray paint) during the QC and packaging process. This practice has become the standard industry reference for our different springs. Should you encounter fishy looking deals on internet auction sites, please send us an image for product validation, as there have been a very small intrusion of color coded imposters floating around from time to time that to the trained eye, are glaringly apparent from their advertising images and/or descriptions. Sprinco buffer springs are made from high quality Chrome Silicon wire stock which is used in a variety of applications from Formula One to motor valve springs which can see up to 15,000,000 compression cycles in a single race.  CONSTRUCTION SPECS: CARBINE & RIFLE BUFFER SPRINGS ASTM Grade A877 Certified Valve Quality Chrome silicon Wirestock Heat Treated, Stress Relieved and Dual Stage Shot-Peened post winding (Our springs really ARE shot-peened) Impregnation / Plating with Re-Micronized Molybdenum Disulfide formulation Hard plastic tube packaging for protected transport and easy storage (Tubes make great storage compartments for all sorts of gear) Optional Cryogenic Processing Available (Select Item 26001) ADVANTAGES: Increased "lock time" for faster sight recovery and platform stability Consistent spring pressure throughout the duty cycle of the spring, resulting in fewer malfunctions related to spring operation (Especially Type III malfunctions) Improved & consistent cyclic operation. Spring will not change performance for many hundreds of thousands of rounds Greater resistance to heat induced performance degradation Reduced cyclic rate with Enhanced or Extra Power springs and reduce / eliminate bolt bounce with optimal spring / buffer weight selection Reduced operating cost as replacement springs are not needed during the life of your upper receiver assembly. Less downtime and fewer trips to the armorer for spring replacement, in fact, this will most likely be the only buffer spring you will ever need for the duty cycle of your carbine or rifle! Correct spring selection works reliably, consistently, and virtually indefinitely in all properly built and maintained AR platformsMADE IN THE USA
