If I’m using a 10.5” 5.56 with a carbine length buffer tube, this buffer should still work, right? It does say works with any carbine length buffer.

Product Info for Kaw Valley Precision Solid Stainless Steel Heavy Buffer

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 ytheir blow back system a fighting chance. Do yourself a favor and fine tune ytheir setup for the softest shooting PCC possible.image
