However you don't want to be in the thick of the action and think, "oh no, I'm almost out of water!"


There's always the bladder safety reserve... that's the beauty of a gun like that!

I suppose it could be "lethal"..... if one held it by the muzzle, swinging it wildly like a baseball bat. Self-promoting articles should be viewed with caution.


I was wondering where they were going to get all the extra power needed to make it a lethal weapon... They are essentially generating an atmospheric mix of H2 and 02.

What was the rate of fire if you remember? and what method did they use to "seal" the combustion chamber?

It shoots 68cal paint balls. It was a high rof, but no more than the other paint ball guns exhibited there. It was no BFD. They didn't share any details on the mechanism. After each demonstration, ALL of the exhibitors allowed the War Fighters in attendance to come to the firing line and take a test drive on their guns......except Lund. Lund stated that their gun was a handmade prototype and was to delicate for anyone to handle except the Lund technician. Imagine the Military after providing Lund with $750k +, 2 years of development time and not being allowed to handle it?

I don't suppose it's a great technological leap to also hook it up to a digital rangefinder and adjust velocity accordingly

Surely they could automate the range finding though, use a laser range finder, then highlight target for confirmation before shooting.

At the moment this weapon is extremely cruel to those with dwarfism...

but it is a self contained hydrogen oxy combustion... sure not comparable to real firearms but don't forget that there are ppl who work on introducing gaseous/liquid propelants into real weapons[/quote]

I did some basic BOE calculations on on-board electrolysis guns when the masterclass challenge was first announced. It can be done, but not with the type of power we're usually interested in. I was sketching out plans for a pistol-sized, mid-mix hybrid type device, but in the end the very limited energy density of even lithium batteries killed the project.
If you only want a 1x combustion, it seams like a tippman c3 clone would be the best way to go.

Imagine the Military after providing Lund with $750k +, 2 years of development time and not being allowed to handle it?

I have to ask "where the hell does the money go?", in this type of project. If any one of the more experience members here got their hands on that kinda cash... I... don't... even know what kind of awesome would be unleashed.

It depends on what sort of operation you're running. Is it enough to work out of your garage, or do you need a good manufacturing practice system set up? How do you record and present your progress to your backers? How many people do you need to employ to help you out, and over two years how much will that eat into the $750K? Do you need insurance, an accountant, a lawyer, the hire of a test range, do you lack in-house machining facilities? What software are you using for design, how many licenses did you need to buy?

There's a lot which most people take for granted...

Not sure what the terms were for that $750K, but if there was any intent of mass production - that could very quickly disappear with machinery cost alone, not to mention any possible automation line layout, tooling, training, and everything else JSR said.


GMP... :P you can tell your from the pharma world lol. Where I last worked - it was all about following the GAMP5 rules - a.k.a. automated pharma on a merck/pfizer/GSK scale.

It's a mindset you get used to, hard to grow out of ;)

Fair enough. So make a pump with a box mag. I'll wager that's still cheaper and more reliable than the subject of the thread.

... as well as retaining the lethal option.

Something like the M26 will do nicely :)

Until recent years, I owned a USAS-12, but I've always preferred my 12ga, 18" barrel, Mossberg pump.
