My home state is the once great state of Colorado. It has since degraded into a Liberal cesspool with the administration trying their best to catch up to California.

I am interested in the M&P 15, but of course have to have it configured with a 10 round Mag. If, by chance, a person happened to have on hand pre-regulation full capacity Mags, is there anything in the design of the rifle that would preclude the use of such magazines?

Nope. There is no CO specific AR lower...yet.

Hypothetically…….no.

Nope, they all should all work.
