Mike is fine if you just want to order and buy something. My exchanges with him are mostly very brief and usually he delivers what I want/need. The times I have had a problem he's eventually resolved it but not without a bit of assertiveness from my side.
Appreciate you currently have a new gun from Mike and to be honest it should go back to him to test and confirm working (although I'd be shocked if he'd sent it without this step first) then there is a brilliant alternative now in the shape of
Hi Capa Hub
I've met Kyle face to face and he's a proper chill guy, was as excited about his own hi capa and projects as you would be piecing them together and where I consider Mike one of the "old school" type sellers, Kyle is the "up to date" version and has a real drive to go forward and do more as well. He's also a proper skirmisher as well which makes you a lot more comfortable. Sometimes I feel my "skirmish" requirements were a bit of a burden to Mike taking his time from "real" IPSC types.
