Blitzkrieg Components / KynSHOT 9mm AR-15 Hydraulic Buffer
Blitzkrieg Components partnered with KynSHOT to develop a top-of-the-line 9mm specific AR-15 buffer using KynShot's Hydraulic Buffer Technology. The Hydraulic Buffer body uses hydraulic shock absorption to dampen the impact of the bolt at the rear of its travel and also to dampen the forward impact of the Buffer's weight as it chambers the next round. It's 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 using any 9mm Parabellum (9x19mm) ammo type. It provides the softest recoil impulse of any 9mm buffer we know of and will allow very fast follow up shots, improved accuracy and less wear on the firearm. Designed to work in everything from 3.5" pistol and SBR barrels up to 16" carbines, either suppressed or unsuppressed and with any type of ammo. Normally the only difference is what buffer spring needs to be used. The hydraulic fluid and seals are made to meet mil-spec requirements and have an ambient temperature operating range of -30F to +150F.
The blowback operation of the 9mm AR-15 drives a very heavy bolt much harder than a standard AR-15 BCG and it needs to be dampened as much as possible to optimize the system, reduce wear on the firearm and reduce recoil and sight movement. For this reason, the buffer is a very important component in getting a 9mm AR-15 to run at its full potential. The design is simple, yet very effective and will feel softer and run quieter than any conventional AR buffer. Spring noise is also dramatically reduced using this buffer. The length of our buffer stops the bolt just behind the bolt catch on a 9mm AR-15 without the need for a spacer.
Buffer Spring selection is very
important to optimal performance and minimal recoil and sight movement.
There are a variety of factors that effect how hard your 9mm AR cycles and which buffer spring will be best. These include barrel length, suppressor use, ammunition energy, bullet weight, bolt weight, and hammer spring weight. We recommend running a pistol caliber AR with the strongest buffer
spring that runs reliably and cycles fully in your weapon. This
sometimes requires a bit of trial and error on the part of the shooter
to find the sweet spot since every build is unique and even guns with the same build specs can
run differently and require a different spring. With this buffer a 308 rifle spring usually works with 14.5 & 16" barrels with most ammunition and is preferred when you plan on running a lot of more powerful loads and/or heavy bullets or are suppressed. A 308 carbine spring is a good all around spring choice for 7-16" barrels when running most typical 9mm ammo. Barrels under 7" often require more trial and error to find the best spring for your specific build. Below is some general guidance to use as a starting point in spring selection..
Spring Selection Guidance:
*The following is provided as general guidance as a starting point in spring selection
SPRINCO Orange 308 Carbine - 7-16" barrel unsuppressed, 6-14.5" suppressed
SPRINCO Red 223 Extra Power - 5-8" barrel unsuppressed, 4-7" suppressed
SPRINCO Blue 223 Enhanced Power - 3.5-6" barrel unsuppressed or suppressed
SPRINCO White 223 Standard Power - 3.5-5" barrel on softer running guns
SPRINCO Yellow 223 Reduced Power - 3.5-5" barrel - very soft running guns unsuppressed
JP 308 Rifle Ground & Polished Spring - 14.5" & 16" barrel - hot/heavy bullets or suppressed
JP 308 Carbine Ground & Polished Spring - same as Sprinco Orange (quietest spring)
JP 223 Carbine Ground & Polished Spring - same as Sprinco Blue (quietest spring)
