Slightly used RRA LE Entry stock assembly - one trip to the range and I realized it was too short, even with the extension. Stock assembly includes carbine length buffer tube, buffer, and spring. Stock screw (A1 screw) is MIA, however, if you also purchase the extension, you will have the screw you need - [b]$45 shipped[/b].
DPMS stock extension - adds approx. 1" to your stock. Also slighlty used. Includes stock extension, buffer tube spacer, and two extended screws (shorter one to be used with the LE or A1 style stock, longer for A2) - [b]$23 shipped[/b].
Buy both for $63 shipped.
