how am i acting like a child? im not the18 year old who plays with nerf guns.
Because you're showing everyone here that you have the intelligence of a toddler. Why does me having an interest in dart guns have any bearing on my maturity level, or how does it even relate to my age? I own a vehicle, I drive, I'm in college, I'm temporarily out of a job, I just got out of a relationship, I hunt, I own around 6 firearms; Am I suddenly an adult because of what I do or enjoy?
Why can I not have an interest in an object? Is it because the object is designated for a different demographic? Does that mean I can't wear an Ushanka because I'm not Russian, or a Peacoat because I'm not a sailor? Am I not allowed to take interest in the engineering or operation of a toy?
Does that mean kids run the factory where toys are made? I mean, they'd have to, since adults aren't allowed to have any interest in toys or toy making, right? Yeah, that has to be it, children invent the toys and produce, package, ship and sell them, obviously. Oh, that also means you're not allowed to play T or M rated games because those are designated for 16+ and 18+ (aka "big kids" to you).
Stop being such a loving handicap and at least make an effort to
think once in a while. It's not that difficult (well, it might be for you in particular).
Is there a mod that enables the guns with magazines (Longshot, Longstrike, Recon, etc.) to fire any dart and not only the stream line ones?
No, the design of the guns simply doesn't support that type of operation.
