COLT M16 FLAT TOP
Excellent original Colt upper receiver. The barrel is marked with the letter "C" and also has the government mark. Extremely lightweight and the quality is amazing. This is an excellent piece of engineering. You have no idea how happy I am that I made the right decision.

Colt 20” 5.56 complete upper W/ Magpul handguard
Solid looking & functioning upper. BCG & charging handle cycle by hand just fine with a bit of extra lubricant. Fresh out of the box, after removing the protective metal wrapping, the whole upper & barrel had plenty of factory lubricant on it. I have yet to shoot it because I am waiting for my A2 stock, A2 handguard, and buffer tube to arrive. I will point out that there was a very small scratch on the barrel by the 1/7 twist marking, but I do not mind. This upper is gonna be paired with a surplus style A2 lower, so a singular tiny scratch wont look out of place at all. It’s still gonna function great, bc after all, it is a Colt upper. It has the typical keyhole stamp marking on the left side of the upper, as well as the “M4” marking in between the upper & the delta ring. Relatively fast shipping considering I live in AZ. Well worth the price.
