i just bought a new colt match target lower. i want to mount a dissipator upper on it. i am looking for a dealer or individual that can sell me the complete upper with b/c/ch and offers a short term layaway. i don't care if it is a2 or a3. i would like it to be set up for a colt lower so that i can mount it right away as soon as i recieve it. thanks, tommyhy.gif oh, it needs to be 5.56. 1/9 01/7 is ok.
