Selling these short Vietnam style midcaps these are also great for M4 DMR build as easier to lay prone with. Also good for hpa guns as short ans if running mag adapater tend not to get in way as much as full sized m4 mag.

each should hold 110 but have never counted. definitely can take full pistol loader with 100 BBs
