Now for me this is the very truth of the hobby I try to avoid , if I let this truth out of its box I’m never gonna buy a gun I like the look off ever again id just run the simplest M4 with a box mag and that’ll be it ! When I choose a new gun(immaterial if it’s ‘new’ or 2/3/4th hand or what ever) I have to like the look of it first , if I need to ‘tweak’ it a bit for optimum performance ? That’s not a problem I will do something with it if I have too . I’ve always been ‘form over function’ with all my guns .
