TOKYO MARUI MP5A4, comes with one Midcap and battery. No internal problems. Mostly stock but has new bucking and cylinder. Only problem is the mock charging handle. Which is broken and missing. Can be replaced for $15 bucks-ish. Great CQB gun that performs well. Shoots just under 320 fps. Rather firm on price. Shipping is included in price. Comes with one midcap one 9.6v battery and an additional fuse. Thanks for looking.
