I am looking at a semi auto gun that is described as having a 11.5" upper with a 5.5 inch hider. I don't have pics to look at but the seller says the upper has CH on the upper receiver. It is an upper with A1 sights.
CH is a Colt marking but did Colt make any 11.5 inch uppers with attached 5.5" hiders?
I wanted to know if somebody maybe used a Colt upper to make this or if it was a factory setup?
The upper is described as like new.
The lower is described as excellent, not Colt but a known maker.
Thanks for your help.
