Buffer,tubes,and springs

[choppertime]

Planning on a ar build 20 inch barrel rifle length. Why is it being difficult for me to choose a buffer System? So many different ones to choose from ,one system says fits this an one says fits that. I'm going with a fixed stock...lead me to the right buffer system,I don't care if it makes noise (not going to get a JP one) I already have a jp 308 with a prs stock I never have checked the buffer on it, anyway bigger money is going toward barrel,trigger,bolt.......thanks for replys

If you're going with a fixed stock and a 20 inch barrel, you're decisions are made.....

Rifle length gas and a rifle buffer and rifle receiver extension.

Yup, not a lot to consider with a fixed stock and 20" rifle.

Here's a pretty good guide to buffers and buffer springs: https://www.wingtactical.com/buyers-guide-for-buffers-buffer-springs/ although for you not a lot to consider... still useful info.

All those options you see are for variables you do not have. As others have said, standard buffer tube, standard rifle buffer and spring.
