can anyone give me an Idea of year this Colt was manufactured and model number Thanks serial is sp242XXX 20" sporter Hbar
Describes my R6600K to a T. Mine is serial # SP248xxx.
K= it came from Colt with a .22lr conversion kit. Without the box you would not know if yours was a K model or the R6600.
I also have a AR15-A2 HBAR Sporter like yours SP217xxx except it has the bayonet lug, non cut out bolt carrier
