Do you guys like your 556? i have been kind of whatever about it but with the price of gas piston uppers, i was thinking about just getting a whole rifle.
i know they accept AR mags, i was wondering if they accept collapsable stocks like vltor and magpul.

They accept all AR spec buttstocks.

I have an ACE Skeleton stock on mine.
