I posted another thread about how I picked up two uppers dirt cheap. After closer inspection, I'm not sure exactly what I got, or how much its worth. The following is all the markings and info I have. Any Info is appreciated!
Colt Upper; 20" Barrel is clearly marked C MP 5.56 NATO 1/7 Flat top upper with carry handle, marked C AF Elevation wheel marked 6/3 Has M4 feed ramps Has a bolt carrier that is VERY different from my new colt bolt carrier Unknown Upper; 20" barrel clearly marked E MP 5.56 NATO 1/7 Grey A2 upper (not 100%solid, has pinned on rear sight) with NO MARKINGS on upper Elevation wheel marked 8/3 Does not have M4 feed ramps, but the barrel looks as if it does Has no bolt or carrier Front sight gas block is marked N (RI) 2 Pic of the Colt marked bolt (bottom) next to a new production colt bolt.. I believe the top bolt which came out of a colt that I bought last year is actually a full auto bolt, and the one I just picked up is an sp-1, which will take a sear with an added block? http://i416.photobucket.com/albums/pp249/shrugod/66.jpg Pic of the ramps of the colt upper, the unknown upper has the same shape barrel but no cuts in the upper itself http://i416.photobucket.com/albums/pp249/shrugod/55.jpg The unknown upper http://i416.photobucket.com/albums/pp249/shrugod/11.jpg The Colt upper http://i416.photobucket.com/albums/pp249/shrugod/33.jpg Both colt and unknown have this inlet http://i416.photobucket.com/albums/pp249/shrugod/44.jpg Unknown upper gas block marked N (RI) 2 http://i416.photobucket.com/albums/pp249/shrugod/99.jpg |
| the bolt carrier does have a c stamp on it. The unknown upper has the same barrel markings as the colt, in the same font size and everything, but instead of a "C MP" it has a "E MP". I'm hoping that the identification of the barrel on the unknown will help with the identification of the reciever. I cant find much online about the E stamped barrel, besides that USGI's have had them. |
