First up is the G&G combat machine. Mostly stock. Fps is around 370. Has a flat trigger and a magpul hand guard. Only bad is it only has full auto and I don’t know why. It’s wired to the front hand guard with deans connectors. optic not included Second is a Blackwater M4 Has an upgraded piston and spring. Also shoots about 370 fps. Has a different stock on it to allow different size batteries as it’s wired to the rear with deans connectors. ** red dot included, amp is not** Both guns come with a hicap mag. They both work, I just have no use for them.
