C marked
Same trigger that came with the Colt 6920 I bought a few years ago. I liked it so much the original is going back in the Colt and bought this one to go in my PSA carbine. Side by side they're identical, with these having maybe one or two more parts that are "C marked". Great trigger and looking forward to breaking it in.

Colt OEM AR15 / M4 Mil-Spec Fire Control Parts Kit
The great thing about Arms Unlimited / AU, is that they always come through and have never misrepresented parts or items we have purchased through them. They created dealer wholesale accounts for FFLs to grow and supply many Colt items that are hard to get. They fill a big Nitch. Last, they are what is represented, COLT Genuine Parts.

The Best
Waited to find a genuine Colt Parts since most of the other stuff I have tried has been junk. Goes together tight and looks great. I have built at least 20 lowers over the years and Colt is the best.
