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….Add a suppressor, and the increased back pressure can cause tremendous damage, without properly tuning your blowback system. The KVP 10 oz tungsten blowback buffer helps tame the destructive forces in suppressed and standard blowback AR15’s. Do yourself a favor and fine tune your setup for the softest shooting PCC possible!
Due to tungsten weight variation, actual weight of the buffer is between 10.3 and 10.5 ounces.
10oz 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)
- 10.3-10.5 oz actual weight (tungsten weights can vary slightly)
- 4 1/8″ OAL (Buffer spacer is NOT required)
- Stainless Steel Body
- Increases Reciprocating mass and weapon reliability
- Reduces wear on critical internal parts
- Reduces felt recoil
- Designed only for Carbine Length Stock and pistol kits.

Exactly what you need for those blowbacks.

This buffer along with the KVP17-4SS PCC XP spring made a very noticeable difference in the bounce that my old stock buffer and spring offered. Shot a USPSA match this past weekend in sub 20 degree weather with out any issues .

I used this to build a 9mm carbine along with the KVP 9mm Complete Upper and the KVP 17-4 SS pistol caliber carbine XP spring. For the lower, I am using a mil-spec lower with a Hahn adapter block. the combination works beautifully. It is accurate and feeds any ammo, FMJ, Hollow points Etc. I highly recommend KVP.

I have installed (4) of these. I have (1) 9mm SBR, (1) 9mm AR Pistol, (1) 40sw AR Pistol, and (1) 45acp AR Pistol. They are all Blowback guns. The KVP Tungsten buffer helps delay the opening of of the Bolt thus helping to provide enough time and pressure to insure a complete powder burn. I use Unique, HS-6, or CFE Pistol and the former 2 can be pretty filthy in Blowback guns. In the 45ap and 40sw guns this really mitigates recoil. The added advantage is that on guns with suppressors the added Buffer weight reduces “ejection port noise”

But, you’ll need it on a Blow-back 45acp or 10mm AR.
