Ok. Got my brass V3 today from FT and really like it. Only have 2 minor complaints. I only use 18650 batts in any of my mods and in this one some of the threads show when in that mode. I have to be careful not to tighten too much or it fires. So when that happens I back it up abit,so not a big deal.The trigger button works itself loose frequently. So I tighten it up. My question is this. Has anyone applied locktight and then tightened it to where you want it? If so how did that work? I really love this sturdy beautiful hard hitting mod but the firing button problem is annoying. Suggestions?
