As the question in the title posits, my group is wondering exactly how long it might take to give a weapon a Trigger Adjustment or a Quick Release or what have you. I'm sorry I don't have a whole lot to fill this opening post up with, but that's really about all there is to it. Our group wants to make customisations, but doesn't have a great deal of time to work with and so we're simply wondering how long it would take to make the modifications…

My buddy who customizes many of his firearms says that a trigger adjustment would take about a average on hour, but it really depends on the trigger. As far as the quick release he has no idea and doesn't even know if you can make a mag release faster (they are pretty fast already in real life, by the time you get the new mag up the old mag has hit the ground.)

Edit: You can change out the mag release for a better one, there's a youtube video of a guy showing how to do it with a ruger and it doesn't take long at all.

Also products like this would make it faster and wouldn't take long at all to install.
