I have an opportunity to buy a Colt Sporter Competition HBAR with SN CH000xxx. It has a detachable handle and a 20” barrel. It appears unfired by the owner and has this bolt carrier with its lower half chopped off. Bolt lugs are all black, which could mean no wear.
From published lists, the year of manufacture is 1978.
What is a fair market value for this?
Are there anything significant, good or bad, that I should know about this rifle?
Sorry but I wasn’t able to take photos to post.
