It really depends on the market and location. Some states (ban states), they can bring $3000 and up easily as they are very restricted on what they can own. Other states, you are realistically looking between $1500-$2000, but that really depends on what buyers are willing to pay. I bought my 1977 Colt SP1 Sporter about 10 years ago for $1K. It looks like it has never been fired. That same rifle could, conceivably, sell for $1800-$2000 to the right buyer in most states. Colt’s Reissue is reproduction of the early M16A1, not a SP1. There is quite a difference. If these SP1s were unfired and complete with their boxes and accessories, I would venture to say that you can add about $1500 more to their value. NIB Colt SP1s are worth quite a bit and quite a bit more if they are the early 1960s versions. Your SP1s are late production. I hope this helped.
Here in Florida I’m seeing the mid 70’s to late production like mine anywhere in the $2-2500 area. Like you said, geographical area and what people are willing to spend.
I have not seen “ANY” SP1 in my area for under $2k in quite some time…Colt’s reissue “M16A1” is not manufactured by Colt. It is made by US Ordnance in Nevada and licensed and distributed by Colt,
and they’re selling for $2,500.00. Thank you again for your reply and information, I greatly appreciate it.
The reissues have almost nothing to do with SP1 values. The reissues are priced at considerably more than they are worth. The only people buying them are those who don’t know better or who will spend anything for a rollmark.
Ironically they have softened SP1 prices a little bit because people go “Why spend that much on an old Colt when I can buy a brand new reissue?” Those who know better would always rather have a genuine Colt product SP1 rifle or carbine.
Track a few genuine SP1s on Gunbroker and you will get a sense of what it is worth in the current market. Right now SP1s are gaining traction as people are willing to buy ANYTHING so it’s not just collectors driving prices.
