Sub2000 Gen 2 .40

[John Wick]

Has anyone used this buffer on their Sub2K? I shot mine yesterday, and the metal smack to the face was brutal after 30rds. I order the tube cover/sleeve and the buffer.

Big difference, after installing buffer and tube cover. Fired 120rds without the annoying smack. Installation was 20 minutes for both parts.

Disclaimer - You will lose the ability to lock your bolt, if you do not trim the buffer cylinders.
