AMDTrucking, That looks like the SXK Boxer mod.....Or is it the GingerVapes version ? If its the latter they should fix it for the price it costs ! If it is the SXK I`m afraid you are going to get that with the clones, However I did incur the same problem, nearly threw the damn thing......But I simply did the screw up tight and used "Loctite" Super glue around the nut to keep it secure and it fixed the issue for me.......
