Lame questions, but oh well...

Are there "Hollywood C2 Mfr's." or what?
I assume all modern MG's all post-samples?
Are demo letters neccesary?

How does it work...
Say you want to make a shoot 'em up, would you contact a C2, tell them what you want,
and they show up on set with a pile of guns?

I imagine HWood has a pretty good chunk of the pre-86 MG's out there, so those would be easy...
but what about the new stuff?

sorry...

They rent from places like these guys

Rarely if ever use real firearms. You think they want to spend the time, money and paperwork for real MGs just to risk an injury or death and
untold litigation from mishandling? Would you trust an actor with a real gun on a movie set? No way in hell.

They have professional firearm specialists (gun wranglers) they hire to handle the blanks, setup, prop guns, etc.

Movie production is very specialized - ever watch the credits at the end? Every stinking job has a specialist to take care of it.
But in general studios DO NOT buy real machineguns for movies.
Don't know where you got this notion.

Blank firing dummy guns

I think my notion was they were based off real receivers then modified for blank useage?

Yes, but the firearms are permanently modified by companies like Stembridge Gun rentals (1916-1999), famous for the propane powered minigun in Predator. Some of the Stembridge guns have been reactivated, and sold as firearms again, but Stembridge or the purchaser of the auctioned movie guns handles this, not the studios. They don't want to mess with that stuff. There was a huge auction of the Stembridge movie guns a while back, some were converted back to real firearms.

Good article on how they did it with the GE M134 minigunhere

Im not saying actual machineguns are never used in movie productions, but if they are it's the movie gun rental agency that handles it all, not the studio, and they are modified so as to be incapable of firing live ammunition. It's like hiring a stuntman.

I almost bought a full-auto blank firing Uzi one time.  Just for the hell of it.  It was like 350 at the time....I kinda wish I had done it.

Yep Hindsight is always 20/20.

I wish like hell I had bought an M16 back in '81 when they could still be had for $1500 or so. If I had known about FOPA coming up and what it would do to prices.... well can't worry about it now.
