colt sp1 bcg and sp1 stripped upper value??

[jojok]

I have a sp1 bolt carrier and stripped upper both like new came out of my fathers sp1 I was wondering what they where worth

Is the bolt carrier "shrouded" or "unshrouded" (beveled) in the firing pin area? Makes a difference in the value. The unshrouded ones are less desirable. Also, is the gas tube key installed and properly staked? For the best ones, retail should be in the $80 area.

sp1 bolts--are used with lightning links for full auto. check out what you have here. http://www.quarterbore.com/nfa/lightninglink.html

as far as price--?????? whatever the market will pay. stripped uppers--depends on someone doing a period build. gunbroker.com would be a place to start.
