G&G F2000. It's wired to deans. Gun shoots crisp in both semi and auto. Unlike other f2000s fro g&g, this gun features a working semi and full auto selector. Semi does work and the issue was fixed on this gun. The gray body lever is loose but can be tightened with some tape, as well as a rear sight that stays upright permanently. Doesn't affect much as I usually use it with my red dot. Great gun and super reliable.
