2005 Colt lowers will take Geissele SSA and SSA-E triggers if I become so inclined.
Newer than that take any triggers.
Guess I could sell one of my 5 LEO 6920's if I really wanted to, which I don't, including 3 unfired 2015's with Kryptek Higlander Magpul furniture that are all small pin.
Everybody and their cousin wants a Colt. Easier to sell than phugkin ice cream.
What was your point, again?
