Pistol caliber carbines such as 9mm, .40 S&W, .45 ACP, and 10mm are a blast to shoot but can be tough on AR-15’s internal components. Without a properly tuned blowback system, you run the risk of being overly destructive on internal lower parts. Runing a blowback AR15 with a suppressor can further increase the risk for damage. Adding the KVP 7.5 oz Stainless Steel buffer is the best way to give your blow back system a fighting chance. Do yourself a favor and fine tune your setup for the softest shooting PCC possible.
7.5oz Buffer Features:
- Use in 9MM, 10MM, .40 S&W, or .45 ACP blowback AR systems
- Increases AR-15’s dwell time in blowback setups
- Quiets action (better for suppression)
- 7.5 oz
- 4 1/8″ OAL (Buffer spacers are NOT required)
- Solid Stainless Steel Construction
- Eliminates annoying buffer “rattle”
- Increases Reciprocating mass and weapon reliability
- Reduces wear on critical internal parts
- Reduces felt recoil
- Designed only for Carbine Length Stock and pistol kits.

The additional length and mass of this buffer made a big difference in the cycling of my 9mm upper. The prior buffer would stick in the tube. This one glides smoothly.

Something seemingly as simple as a buffer can actually get rather complicated when building an AR in a caliber other than 5.56. This heavy buffer is perfect for the blowback operated 9mm AR.

Good heavy buffer.

Excellent just what I wanted

Softens felt recoil, however extra heavy spring makes charging handle somewhat stiffer to operate, will try old spring just to test

When you pull out your buffer and spring of your blowback pistol caliber AR and replace it with the KVP 7.5 ounce buffer you will never look back. It’s hard to believe what a difference that thing makes in a blowback gun. Despite the length your bolt hold open will still work too. Your gun finally feels like it’s not beating itself to death with hot loads, your follow up shots are faster and maybe most important of all you don’t have to worry about the blowback action breaking your hammer or bolt catch anymore. This thing has no rivals. Buy it. When I do a 45 super or 10mm gun rest assured KVP’s even heavier 10 ounce will be the first part I buy. Use this 7.5 for 9mm.

Very high quality. The price is spot on too. Definitely going to recommend this to everyone.

there are plenty of 7.5oz buffers, but this one is long enough to only allow the bolt to move 1/8″ past the LRBHO catch. Must Have if you have a LRBHO pistol caliber carbine.

7.5 oz stainles solid buffer is of great quality. Functioned fine and really made a difference in my 9mm AR pistol. It shoots smoother and ejects better no more brass getting hung up in the ejection port. I have been very pleased with Kaw Valleys products and will continue to use them.

If you are running a PCC probably wanna run this buffer. Just sayin’.

I relied on knowledge gained from an old Armorer, ie; problems with AR’s can generally be fixed with new buffers or buffer springs(proven true for me before). After installing I could not get bolt to retract fully. WC glued a spacer into the buffer tube, new problem identified. Well I have a nice paper-weight if a need for one arises. Need to thank Tech. Support @ Kaw because they new exactly it was a spacer…
