Colt uppers are available as a basis for custom builds. These units take large pivot pins and are fully finished and ready to be built up on Colt or clone receivers of the appropriate dimensions. The Colt uppers are hard anodized black to match other Colt components. They are available in the following configurations:
Carry Handle 5.56X45 mm: This is the U.S. military M16A2 configuration, stripped and ready for a forward assist, ejection port cover and 800 meter back sight.
Carry Handle 7.62X39 mm: As above but chambered for the Soviet M43 cartridge.
Carry Handle 9X19 mm: This is similar to a baseline carry handle M16 receiver without shell deflector and with no provision for forward assist. The carry handle takes the original A1 rear sight.
Flattop 5.56X45 mm: This is flattop, MIL-STD 1913 Picatinny rail version of the Carry Handle 5.56X45 mm unit and comes with forward assist and dust cover fitted. The rail has white alphanumeric markings for each slot so that optics can be removed and replaced, repeating zero.Full disclosure: If you purchase from Brownells, I will receive a small commisson.
