    Good quality...

    This is a nicely made buffer tube kit, on par with the likes of Aero Precision. The roll pin on the buffer that holds the weights inside in place is nice and flush with the outer surface of the buffer. Buffer weighs 3.03 oz on my cheap scale. Checks all the necessary boxes. Would recommend.

    Color is perfect. All black for your all black build or don’t want the usual gray these come in. Easy standard installation for milspec.
