Good catch Ragnarok. Thanks!

Jack's... The Caseman (is that how it is spelled?) was very complicated when compared to this GSMG. The Caseman had a bolt separate from the hammer, and fed his bullets into a breech area before the hammer hit the valve... and the sear/trigger assembly had 3 or 4 parts hinged all inside the reciever. The GSMG has a hammer, a sear, a trigger, a valve... that is all, but still uses a closed breech. A high pressure version could be developed after the standard is accepted.

Thanks guys!

A closed breech, but surely not a locked breech? It would be interesting to take a look at the inner workings, though if this is information you'd prefer not to disclose for potential patent reasons we can understand.

Presumably the gas is unregulated, what pressures does it operate at? For the sake of potential customers it would be good to provide details of performance such as shots-per-tank, as well as actual velocity figures for specific ammunition weights in both calibres (which presumably are lower for CO<sub>2</sub> than HPA).

Have you considered scaling up the calibre? There are existing 0.25" barrels and ammunition so it's not really a logisitical problem. You can go even bigger with 0.44" or similar and use muzzle-loader ammunition ;)

Did you send Ant a private message about this yet?

You can tell how awesome a cannon is by the pressure used.

sticky I figured he would find this himself...

jack's... no exact figures for certain munitions until the final production version is released. and yes you are correct that the specific inner working need to stay under wraps for a while ;) locked breech? you are thinking in conventional bolt/breech design- closed, locked, sealed... are all relative to the fundamental design type of the system and are highly subjective.

were you to define 'locked' breech as a system when pressurized would resists said pressures mechanically until exceeding the yield strength of the materials used... then yes, the GSMG uses a locked breech.

I find it mildly amusing that in the write-up you make it sound like it could be useful in combat, then you scroll down and to look at performance and read:
30 round magazine capacity (good)
.177 or .22 caliber (bad)
Fires BBs or pellets (okay)
Muzzle velocities up to 600 fps with the stock barrel (killed it…)


On the other hand it would be fun to use it for trap shooting… :D


Does it have a rifled barrel?
If so why do you say it can shoot BBs when BBs will ruin the barrel?

600fps is tolerable, but with guns like the AirForce Condor, there’s no reason you shouldn’t be able to get it to shoot 1000fps in .22


The Caselman AMG did nearly 800fps in .32 caliber with 100gr slugs, it may have been a little more complex, but it performed better.


Also “high strength engineering resins”… in other words: plastic… :roll:
And I happen to like the Red Ryder…


I’m not much of a fan of the look; lasers, red-dots, and bipods… all that stuff does it make the gun heavier…
And what, no iron sights?


The airgun is designed for the rugged sportsman with durability and dependability as core attributes.

Wait, are you suggesting this be used for hunting?



Now, just because I don’t like it, doesn’t mean other wont, and as a plinker I must admit it would be fun to shoot, if it had iron sights. :)

Sorry… I’m just old school… :D



You asked for feed back! :lol:

Damn this look really awesome. Its nice to project like these popping out of the ground. After all this is my dream:) I find the price pretty high for the gun without all the features, as I can buy a tippmann 98 for 250$. Well alright it has a different caliber, but atleast it comes with bottle etc. The bipod is kinda big compared to the length of the airgun... The milling job at the top (the rail) is great> reminds me of the tippmann platinum. You said that the valve is similar to the crosman 357... not sure what the internals look like. But I assume ur valve is inline with the barrel and the air is supplied infront of the hammer. So it might look like the tippmann paintball markers:

Oh yeah btw if you really want to have reactions why not post this gun in the cannon bbmg section. If you post it there with more pics ppl will be amazed. But yeah overall> great look, prob great balance+feel. I would like to know if you have a semi/auto button or if you have to open the gun for that. I might have missed that on the movie. Cool! I would like to c some more specs though as other ppl mentioned.

Wow, impressive.
A diagram would certainly make my day. (and the one of others here)

Now try to make a 16mm marble one! :wink:

Target shooting? Thats a sport too.

ant you are close, yes it is inline. the trigger controls semi/auto. pull the trigger a little- semi. pull the trigger a lot- auto.

thanks judgment for your feedback. is that scope on your avatar old school?

Hehehe… first off it’s “Judge”.
Second, I just want to make sure you know that I meant absolutely no offence by what I said, not tryin’ to be mean. ;)
If you want me to really like it, it has to be made primarily of steel, brass, or wood, or at the vary least have some nice wood furniture (grip scales or a stock).
For what it is, it’s actually pretty slick, it’s just not my cup o’ tea… ;)


And VH_man is right, it’s a scene from Back to the Future part III:
“It’ll take the fleas off a dog’s back at 300yards and its aimed strait at your head, Tannin!” ~ Doc. Brown 8)

:roll:

And no, technically it’s not old school since Doc is from the future (1985)…:lol:
EDIT:
And even though normally I don’t like scopes, the sheer fact that it’s made using 1800’s technology and constructed primarily of brass is enough reason for me to like it. :D

:lol:... maybe that's the problem :roll:

That's the nicest built and shooting semi-auto .177 or .22 airgun I've seen.
The fact it's full-auto also makes it awesome IMO.

I've read the replies but I didn't notice if the white handled auto was your's also (from youtube video)?

Sure would like one in .22 cal.
Now I know what I want for christmas. 8)

that was an early concept test... we were comparing stacked tube to inline constructions.

Okay my thoughts of the GSMG:

The GSMG looks like an AGD paintball marker. Which adds a bit of confusion when compared to traditional airguns .The style makes it difficult to take the gun seriously from first glance. I think for selling appeal the GSMG needs to look more like a real rifle (in todays world of modular firearms that can be an easy fix). A longer barrel certainly wouldn't hurt( think mock silencer). Neither would a stock.With the addition of a few side RIS rails and a good stock the GSMG would become heaps more marketable.

As far as performance goes, the FPS needs to be raised. Go for the high pressure. I'd absolutely love to see this gun at 1,000 fps. I could guarantee a unique rifle with that speed would sell like hot cakes. Another issue that may prove problematic is magazine size. If that 30 became 60. I would be drooling. Maybe even a 200 rd. drum mag(shameless plug). You have to think, folks buying this gun are gonna buy 1 maybe 2 mags extra before they call that good. If they get 20 seconds of firing time for 2 minutes of reloading time they are gonna get frustrated.

Over all I think the GSMG has great potential but I can surely see some things that could be improved to ensure the sales of this gun. Keep up the good work. The first run looks nice.

I have always thought BTTF III was a fairly good movie...not quite up to BTTF I standards, but a whole lot better than the very forgettable BTTF II.

I knew I had seen that scene somewhere before but could never place it. Nice find there VH!!

Great. I thought it was looking at your avatar of course.
That one was linked to atleast twice by two respected members here who are semi/full-auto fans. This new preview looks much better IMO.

goathunter gave some feedback:
IMO a 1000fps version he mentioned would "sell like hotcakes" until it got banned.
Maybe a seperate upgrade kit (springs or valves) or higher priced model would prevent that. (Evil suggestion).
Longer barrel option would be nice if it doesn't interfere with the mechanism.
600fps in .22 is plenty powerful for a short airgun and 600fps in .177 is not to bad IMO. I agree, Higher capacity mags would be nice also. Thanks tgwms!
