KJWorks KC-02 Tactical Carbine (still in box)

I have a practically brand new KJWorks KC-02 Tactical Carbine with 6 gas tight magazines (5 30rnd, 1 22rnd stock) still in the box! I purchased it in late september and used it at one game day 2 weeks later. IT IS PERFECT! just not what i thought i was looking for. The upgrade potential for these RIF's is endless. join the KC-02 owners group on a well known social media site and you'll see what I mean! it is locked to semi-auto so it make a great platform for a DMR build, and they have been hailed as one of the most accurate GBBR's out there! I'm looking for £300 including the 5 extra magazines. I'm open to reasonable offers, but the RIF is literally brand new. I can send more photos through WhatsApp. 07960792747
