Buffer question

[Clyde777]

I have a geissele socom upper and I have their super 42 braided buffer. The upper is a 14.5 midlength set up will that buffer affect reliability in a negative way with a 14.5 midlength? Its recommended for 14.5 carbine length systems.

I think you misread their information:

The Super 42 is for use with Carbine length buffer tubes and is not compatible with rifle length or A5 buffer tubes/receiver extensions.

We do not recommend the Super 42 with 300 Blackout subsonic ammunition. The Super 42 Spring may be too powerful and not allow the rifle to function properly.

As long as your lower has a carbine (or pistol) extension, it should work.
