I have an early 90's Colt HBAR lower. I just purchased an early Colt M4 marked upper. The upper is a slightly lighter gray than the lower. After receiving the upper I test fitted the two to check the color match and there wasn't a problem. It uses the front push pin with the screw. Now that I have mounted a Colt 14.5" SOCOM barrel the upper and lower will not go together. I was able to get both the front and rear pin in, but not at the same time. I applied quiet abit of force but didn't beat on it. Has anyone had this problem or heard of this happening before? Any suggestions?
Thanks
