Bought this a while ago because I wanted a bulpup which takes m4 mags. I had to fiddle with it to get it feeding consistantly. There is a piece of kydex in the back of the magwell which makes the included asg midcaps a tight fit and feed perfectly. Shoots about 300fps. Selling it to fund upgrades for a new sniper rifle and because I have moved to using ak platforms in general. The included rail system is rather rare. Ive only seen 2 for sale and they went for £80 +. The original scope is also included and works very well. price includes postage and fees
