Blitzkrieg Components has released a purpose-designed buffer for 9mm AR-15 platforms. The new buffer differs by using a polycarbonate piston head which encases a shock absorber. Blitzkrieg claims that the new buffer design “eliminates buffer wear” and “runs completely quiet.”

The buffer is available direct from Blitzkrieg for about $67. If you would like the complete buffer assembly and spring, you can purchase it for about $87.

Features

• Machined Stainless Steel Buffer Body
• Quiet Buffer Operation
• No Spring Noise
• No Buffer Tube Wear
• Maintains Excellent Buffer Alignment in Buffer Tube
• 2 Stage Buffering Action on impact

Full description from Blitzkrieg below:

Blitzkrieg Components partnered with CTS Engineering to develop a 9mm AR-15 buffer using CTS’s Patent Pending AKTIVE Buffer Technology. The AKTIVE Buffer design uses a solid Stainless Steel buffer body and a 2-stage buffering action to cushion the impact of the Bolt/Bolt Carrier. The buffer has a hard polymer piston head at the front that encloses a captured elastomer shock absorber and has an improved rear bumper. The 2-stage action consists of the piston head compressing the internal elastomer shock absorber, followed by the compression of the rear bumper, creating a much softer impact at the rear of the buffer tube. The impact of the bolt on the barrel as it goes forward into battery is also less than with a conventional weighted buffer or solid buffer. The hard polymer piston head has been redesigned to support the unique 9mm AR-15 application. It accommodates the solid rear profile of 9mm AR-15 bolts and it provides optimal alignment at all times within the buffer tube. Furthermore, the polymer piston head eliminates buffer tube wear and runs completely quiet. The rear bumper is not only more substantial than a convention bumper, but it is secured to the stainless buffer body with a bolt instead of a flimsy roll pin. The blowback operation of the 9mm AR-15 drives a very heavy bolt (normally16 ounces) 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. The design is simple, yet very effective and will feel softer and run quieter than any conventional AR buffer. Spring noise is also eliminated 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 completely eliminates this vibration and noise. The length of this buffer stops the bolt just behind the bolt catch on a 9mm AR-15 without the need for a spacer. We recommend pairing this buffer with our 9mm AR-15 carbine buffer spring or a high quality .308 AR-10 carbine spring to sufficiently slow the rearward bolt velocity. Our high performance buffer springs are available separately as well as in buffer/spring combinations for the ultimate in strength, consistency and extremely long service life.
