Blitzkrieg Components / KynSHOT 9mm AR-15 Hydraulic Buffer - Standard

The Standard 9mm Hydraulic Buffer model has our normal amount of hydraulic resistance. This is the best choice for short barreled 9mm applications and can be used for all PCC barrel lengths. This buffer has the standard amount of hydraulic resistance that we have historically used in our 9mm buffers. This is a great fit for a wide range of PCC guns. Can be used with our PCC buffer weight to add mass and further slow the action. This buffer is not recommended for use with lightened bolts or short stroke systems.

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. Works in PCC builds with 3.5" - 16" barrels, either suppressed or unsuppressed and with all common 9mm loads. 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. 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 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 in a collapsible stock buffer tube. If used in a fixed stock, we do sell a spacer separately for that application.

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 the best with 14.5 & 16" barrels. A 308 carbine spring is a good all around spring choice for 7-11" 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
JP 308 Rifle Ground & Polished Spring - 14.5" & 16" barrel (without PCC buffer weight)
JP 308 Carbine Ground & Polished Spring - 7" - 11" barrel or 14.5" & 16" barrel (with PCC buffer weight)
SPRINCO Orange 308 Carbine - 7-11" barrel or 14.5 & 16" barrel (with PCC buffer weight)
For barrels under 7" one of these 223 springs may work better:
SPRINCO Red 223 Extra Power
SPRINCO Blue 223 Enhanced Power
JP 223 Carbine Ground & Polished Spring (same power as Sprinco Blue)
SPRINCO White 223 Standard Power
SPRINCO Yellow 223 Reduced Power

Using with our PCC buffer Weight:
Our PCC buffer weight can be used with this buffer to add more mass in front of the buffer. This often softens the action even further and can also allow you to step down one level in spring strength from a .308 rifle to a .308 carbine spring in a typical 16" carbine.

Bolt Weight:
If your bolt has a weight in it, we recommend keeping the weight in the bolt. Removing the weight to get a lighter bolt is not recommended in blowback guns, even if using light competition loads.

Improvements:
Over the last several years our buffers have been run hard by thousands of shooters in just about every conceivable type of build and in intense PCC competition. We have had great feedback from our customers which has resulted in several rounds of product improvements in 2018 to achieve maximum effectiveness and service life. Our goal is the most effective buffer and the most durable.
The buffers we are now shipping have all the latest improvements.

on target October 19, 2018
Reviewer: Chris Klein from Lafayette, OR United States  
dropped it in at the range and you could stay on target!  That and the JP compensator make the 9mm AR a blast and you look like a marksman because you can quickly hit every target!

Eliminated Bolt Bounce February 19, 2015
Reviewer: Mark from Spring Lake, MI  
I just recently purchased a couple of your 9mm Hydraulic 16" bbl carbine
Buffer/JP Spring Combo's.  Up to this point I was trying to use heavy solid
9mm buffers and would experience out of battery discharges in M-16 full
auto.  Not pretty!!  I did a little searching on the net in reference to
bolt bounce and found your site.  I am happy to say that I now have the 9mm
M-16 running great!!! with the new buffer/spring combo, and could not be
happier.  I will be switching my SA 9mm carbines over as well.
