It can only hold 130 rounds and it needs to be reloaded (effectively 100) and the only way to get more ammo is the command. I do not want to have to keep doing the command to give me 9999 ammo, it is annoying as ♥♥♥♥. Fix please because you also seem to have named it something insane and I cannot find the file for it to fix it myself :/

The name of the GMA file is '[tfa]sc-ar_.45_guardian_765732709'
You can spawn ammo from Entities,also you didn't report any bug.It doesn't only hold 130 rounds,that's what you start with.'Insane name'...you made me laugh.Couldn't you just click on Windows Search and type 'sc-ar' ? Anyway,those aren't bugs.

The gun shows up when in a Vehicle.

Thanks for reporting that,but it isn't my addon that is causing that.It's a bug from TFA base.Hope he'll fix it soon.
