Decent FGC-9 instructions

I grabbed the FGC-9 Build Instructions a few weeks back. The guide was pretty clear, walked me through the parts list and assembly without too much trouble. Had a small question about a step, emailed support, and they got back to me in a couple of days, which was helpful. The files downloaded fine, no corrupted parts. Overall, it made the whole process much easier to follow along with. The explanations for some of the finer points were good for a hobbyist like me.

Always reliable files

I got the 10/22 Chassis Files again, since I wanted to try a different filament this time. Download was easy, just like before. Quality is consistent, makes trying new builds less of a headache.

Hey guys, thinking about getting into 3D printing some of this stuff. Is 3D Gun Builder legit or is it just some scam site like I've seen pop up?

J June Patel 4 months ago
Yeah, totally legit. Been using their guides for a while now. They have good step-by-step guides, not just random files.

It's legit. I've gotten quite a few files and guides from there myself. They focus on educational stuff and compliance, which is cool. Not like some other sites that just throw files at you.

Anyone know if they ever do sales on the premium guides or memberships? Was hoping to snag a deal during a holiday or something.

M Mark Patel 4 months ago
They totally do! I picked up a membership during Black Friday last year for a nice discount. Keep an eye out for those big holiday sales.

Yeah, I think they usually have something around Independence Day or Cyber Monday too. Not a huge discount usually, like 10-25% from what I've seen, but better than nothing.
