Everyone of the guns on the market has a group of people who say "It's great" and an equal group that says "It sucks".
The Mongoose is neat - and it's an electrical dream. Totally from the future. They say it out cyclics it's hopper, which I find hard to believe because it has 3 electric eyes that rate the ammo flow and then adjust the cyclic rate accordingly, and on the fly. When it's in "auto" mode it's firing at the exact rate of maximum ball drop.
If I can find an auto hopper for it, I'll be happy as hell. I hate top loaders.
If you want more than $130 for your gun I'm afraid you're not getting it from me. That's my actual marker budget, and then about another $100 in the support gear that I'm missing (Mask, loader, belt, utilities, etc). Like I said, I'm looking to get back into something physical this year where I can get in shape and not spend every free moment turning a wrench.
I have popeye arms from working on cars and I've lost my 6 pack.
