This is a CH marked (no proofs) C7 upper and 6933 barrel marked C MP CB Obviously this not a factory upper but if I wanted to take this and make it as close to a factory 733 (think the movie heat) and wanted to also make as earlier as factory copy as possible then what would be the most appropriate: Lower receiver configuration? Lower receiver markings? Lower/upper receiver color? Bolt Carrier group type? Buffer tube (color and positions)? With or without bayo lug? Many thanks |

The upper, just have the bayonet lug ground off and you are done.
For the lower, it will vary. I used a early 90s Colt 6520 lower with staked 2 position buffer tube on mine. It had all the correct grey colored parts. An original ful auto would have been an A2 lower, marked "M-16A2", greyish in color, 2 position tube with N stock. Some also used A1 lowers, but the later (Heat carbines) used A2s. |
