I'm changing my 20" A2 to a collapsible stock.   What buffer and spring should be used?

A standard carbine spring and H3 buffer has the same cycling group weight as the rifle; or 17.49 oz.

Cycling group weight consists of the weight of the complete bolt carrier group (full-auto profile), buffer, and one-third of the weight of the action spring. Another choice is the H6 buffer which weighs in at 5.2 oz; giving you a cycling group weight of 17.29 oz.
