||This gun has served me for almost a year. I have had no internal issues with the gun. There is absolutely no wobble in the gun, except for the crane stock but that is to be expected. This gun has a good amount of rail space. This gun is definitely for someone looking for a M4/AK cross. The main problem with this gun is that it is picky with the magazines. I made the mistake of buying the wrong magazines and wasted $50. My gun had a defect where the side rails were not 20 mm. The gun performs great though. Range is absolutely amazing if you get the hop-up right, however, the charging handle messes with the hop-up.
