For Sale: 1 Colt SP1 upper receiver, with "CM" Colt / Martin Marietta forge marks. Upper has seen light use. Ejection port cover has slight bend in it on the front edge. Both lug holes are for small (.250") pins; the front one has a bushing in it to bring it down from .312." Perfect for an XM177 clone build. $160 $150 -SPF- shipped, no trades.

USPS postal money order. PM me with questions and for other payment options.

First "I'll take it" gets it.
