I have had this Colt 9mm upper for years. I was going to use it for a .22 build but went with a flat top upper. I bought a Colt 9mm bbl and delta ring assembly from Brownells and put it together last week. I could not get two different pairs of round hand-guards to fit! i have struggled with tight hand-guards before but never like this. I think it is because the gas tube is not there to help align the top rail and the end cap spins a little. The MOE hand-guards went on with no problem I still need a bolt with the Glock cut. Anyone have a spare laying around! =)

"Real men have always needed to know what time it is so they are at the airfield on time, pumping rounds into savages at the right time, etc. Being able to see such in the dark while light weights were comfy in bed without using a light required luminous material." -Originally Posted by ramairthree
