I have a Ruger AR 556 with a fixed collapsible stock, carbine length overall. After handling some ARs with A2 stocks today, I'm thinking I would prefer that instead. What is required for switching to an A2? New buffer and spring?

New rifle-length lower receiver extension tube (buffer tube), rifle-length buffer and spring, A2 buffer tube spacer, stock, and stock screw.

Brownell's has a kit with everything you need:

Thank you very much!

Unsolicited recommendation: Before you go with the standard A2 stock, try to find a Magpul MOE stock mounted on a rifle and check it/cheek it a few times.

.

I actually tried that one too, and liked it a lot. Since I have an attached carry handle rear sight, and the standard A2 front sight, I thought I would go with a more retro look.

Yep. Try an A2, A1, Magpul etc to see which one suits you most. Lots prefer the shorter A1 over the A2.

I'll check out the A1. Do you know how much shorter it is over the A2, offhand? Never mind, I found it quicker than I thought.
