Nothing crazy here just a regular 20" A2. I have loved the looks of the standard M16/AR15 for ever and thought I would build one. JD lower, DMPS upper with a DMPS LPK. Cleaned, oiled and ready for some plinking. The upper locked up to the lower very well. Granted I have not shot it yet I am impressed with how tight the DPMS was, as well as the fit and finish. Only thing I can compare to is my Smith M&P15 which is flawless in range work and coyote hunting. Peace.
