Hey guys, I have a Colt Hbar Rifle with 20in barrel. I want to change the complete upper assembly to another upper asembly. Are there any complete upper assemblies available that will drop in to my Colt Post-ban lower assembly without alterations, other than Colt? Thanks for any suggestions you can give me |

If the front Pivot Pin that hinges the upper receiver together is the smaller of the 2 sizes (I think it's 1/4" diameter) then it's a small pushpin. Sorry, shoulda explained that. More than likely yours is of this variety, cause I'm pretty sure all postban Colts have small pin lowers. -Cap'n BTW, Large pin is .315 diameter. |
