I have a like-new, unfired condition SP-1 up for auction on Gunbroker, but I would be happy to sell it to someone here on EE.
This rifle is in like-new condition and is in its original box, which is a little beat-up, but I have the original box label. It still has the cardboard tube in the barrel, has original manual, black M1 sling, cleaning kit still in the bag, etc. It has two 20-round magazines, but they are Adventure Line, so it looks like somebody may have swapped out or lost the originals. If I can find two Colts, I'll put them in instead.
If you're interested, check out item 45210906
[Edited to add:]
I did reserve the right to sell the rifle in another venue, so I can sell this directly on the EE.
Feel free to contact me via e-mail if interested, or if you need more info.
I will be happy to provide more pictures to an interested party.
Payment would be certified funds or USPS money order, shipping would be UPS or FedEx (not ground) and insurance mandatory. Buyer to pay S&I.
3-day inspection period, only reason for return is if item not as described.
