It's not just out of place, it belies a fundamental ignorance as to gun related technology.
There is pretty much one single feature that we've decided should be reserved for military use: selective fire, aka automatic weapons. A "military-grade semi-automatic rifle" is a contradiction in terms. I believe all standard issue military rifles are selective fire, and no civilian rifles can be outside of extremely rare and tightly regulated situations.
The AR-15 is a counterpart to the M16. It is specifically not a military gun and the major difference is that it does not have selective fire.
