Hoping someone has a pic of a colt SP1 carbine that has had the barrel shortened and the bird cage flash suppressor permanently attached to make it 16"
question: Colt did make a plastic (fiberlite/zytel or whatever) collapsible stock as well as the aluminum one correct?
And, how can I check to make sure the upper and the collapsible stock are actually Colt (I have an SP1 that I want to have the carbine upper and collapsible stock for).
And, did colt make an A1 carbine upper with a small hole or are they all large hole uppers like the one on my 20" SP1?
Thanks for your help
