Blitzkrieg Components partnered with KynSHOT to develop a top of the line 9mm specific AR-15 buffer using KynShot's Hydraulic Buffer Technology. The 9mm Hydraulic Buffer is made from 17-4 Stainless Steel and uses hydraulic shock absorption to dampen the impact of the bolt at the rear of its travel and also to dampen the forward impact 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 available and will allow very fast follow up shots, improved accuracy and less wear on the firearm. Designed to work in everything from 5" pistol and SBR barrels up to 16" carbines, either suppressed or unsuppressed and with any type of ammo. 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. Most spring noise on 9mm AR15s comes from the abrupt stop of a conventional buffer causing spring vibration. Our buffer dampens the impact for a soft landing which eliminates this vibration and noise. The length of our buffer stops the bolt just behind the bolt catch on a 9mm AR-15 without the need for a spacer.
