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:
- Quality
- shipping
- Selection

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.

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.

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

Product is AWESOME. Fast shipping. The product works /drops in without no problems. Price is reasonable. The feel of it helps in keeping the gun steady and on target. I will be purchasing more in the future.�

On my AR 15 full length (16 inch barrel) PCC chambered in 9mm, I have been rocking this KynSHOT AR 9mm recoil buffer for about a year now and it is awesome. I have put about 1000 rounds down range rapidly and single shot increments, and it still feels the same as when I first bought it. Just for kicks, I have also used this on 5.56 and its wonderful. The recoil felt is very minimal at single shot increments, at rapid fire, some recoil will be felt. However, please stick to the suggested caliber this was intended for.
Pros:
- Easy to change out
- Easy maintenance
- afforable
Cons:
- skinny tube on neck makes it feel like it will break easy
Best Used for:
- AR 15 platform buffer tube types
- AR 15 platform blowback pistol caliber carbines (9mm)

My son told me about the hydraulic buffer and how quite they are. They might cost a little more but I'm willing to pay more for a better piece of equipment. I'm very pleased with the results thanks to my son.
