Going through spare parts today and found an old SP1 (i think) upper. It has a large front pin hole, and a small rear. Thinking of using it for a build if I can find a corresponding lower. Does anyone still make a lower in this configuration?
Thanks
What you sould be looking for is an old Colt SP1/Sporter lower before they went to small pins.
IIRC, there are adapter pins/bushings available to make the conversion. If it was mine, I would just sell it off!
DPMS sells adapter pins to adapter a larger pin upper to a small pin lower or vice-a-versa. They are inexpensive and work fine.
