Service:sorry we cannot


What laser can I get for this gun
Service:any laser fit 20mm rail


How Long would it take to ship to Denmark
Service:2-3 weeks


Arrived in around three weeks and works fine for the most part. Biggest down fall is that it either got heavily scratched in shipping or was used before because it is full of scratches. Another thing to mention is that the magazine looks old and had gel balls in it already. Either way a fun cheap purchase I would recommend.
