Most Helpful Positive Review Tames back to battery thump
My FM-9 had an annoyingly harsh back to battery recoil that pulled the optics off target consistently. This buffer greatly improves the feel of the bolt coming forward, optic jump and generally smoothing out the entire recoil impulse. It is kind of expensive for a part on a firearm meant to reduce cost of range trips, but otherwise the FM-9 would be staying home a bunch more.

Is your PCC with it to you?

by Augustus, Verified Owner from MA, United States Written on March 13, 2026
It really does work, It noticeably softens the recoil in my AR9, I have a Stern Defense upper with Faxon 9mm bcg. It's not a huge difference but it's noticeable. Now is it worth $160, the real question you should be asking, is your PCC your weapon of choice to be investing $160 for 20 to 25% reduction in recoil?
Pros:
  • Recoil Reduction
  • essy installation
Cons:
  • expensive for what it is
Best Used for:
  • PCC
Would recommend: Yes

This is a game changer!

by Rich, Verified Owner from PA, United States Written on February 19, 2026
This buffer weight is awesome! I use it in my Saint Victor. The weapon system already had lower recoil, but with this, it barely moves at all. Target requisition is so much better with installed.

AR-9 Buffer

by Andrew Fang, Verified Owner from MD, United States Written on December 9, 2025
Easy to order, great selection at Optics Planet. Selected this buffer due to its similarities to the Hydraulic buffer in the B&T, but for use in my H&R SMG Pistol. Fast shipping and great communication. Great quality of the product.
Pros:

  • Selection
Cons:
  • None

Does what's advertise.

by Soundshooter, Verified Owner from MA, United States Written on June 21, 2024
Easy install. Upgrade the spring as well which made my felt recoil about 50 percent lighter. Works well for quick follow-up shots. That's where you'll see the most impact on your shooting. Not cheap but what is these days. If you compete, it's a must have.
Pros:
  • Good follow up shots
Cons:
  • Not cheap but worth it
Best Used for:
  • Competion
Would recommend: Yes

Works as stated.

by Soundshooter, Verified Owner from MA, United States Written on June 14, 2024
Installed this with an updated spring to replace my tired OEM set-up. This product works as advertised. Lessened recoil by half. Faster follow up shots to make double taps with much greater ease. Easy to install. Pay attention the OEM weight of your buffer. This version worked with the original 8.8oz buffer. KynShot makes different version for the 9mm PCC.
Pros:
  • Better follow up shots
Cons:
  • Pricey
Best Used for:
  • 9mm PCC
Would recommend: Yes

Can't go wrong

by Ghosty, Verified Owner from ME, United States Written on January 31, 2024
These things are an improvement, period. It can be really difficult to find the sweet spot with AR9 spring/buffer weight combos. I put mine in and had to try it out right away, and can definitely tell a positive difference. If I ever build another one, I will absolutely be buying another one of these hydraulic buffers
Pros:
  • Faster follow up shots
  • Softens recoil
Cons:
  • None
Best Used for:
  • Any blowback ar9
Would recommend: Yes
