Hey troops, so I'm an armourer and a pretty new one at that, just completed my second sniper rifle, both were right hand REM actions. I have a Defiance left hand tactical action for a build for myself, so I'm wondering what folks use to tighten the action?
Do you need to buy there wrench? I admit I haven't done much research yet or contacted Defiance, so bear with me , I thought I'd get some comments for some folks here? Thanks
