Homemade vortex strafer flamethrower (build details over in the Project Suggestions section), plus an Orion flare gun converted to fire APS shotgun shells.
-
Homemade load-bearing exoskeleton, so I can carry more gun. More photos over in the build thread.

Nah, I'm pretty sure it's that same production run. I'll call last spring 'recent' on the scale of the design's age

This is the KSC Auto 9C, better known as 'that gun from Robocop'. Older members of the airsoft community may remember these from the 2000s, when they were still in production. Recently KSC put them back into new production, unchanged from their original release. The Auto 9C is a mostly-plastic replica built around a KSC M93R. Unlike the movie gun, this version lacks the distinctive three-round burst setting. While the internal parts needed to enable burst mode are available separately, they are prone to breakage on this design. Only the plastic slide cycles, leaving the barre

Oh, interesting! As someone who has gotten way too into learning about all the different variants of C96 and copies, I would really appreciate if you happen to have other photos or information on hand.

I just tried this on my newly-acquired AOW, and it's jamming up when I cycle the action- both the ghost-loaded shell and the next one in the tube pop into the action, and it seizes up. Any idea what I might be doing wrong?
-
I might do that. Strictly speaking I'm pretty sure it would realistically work fine in its current configuration, with the turret acting as a deflector, but at the very least it will be easier to clear malfunctions and adjust the top with the scope a little more out of the way.
-
Pretty easy, at least as far as the externals. I removed the front sight, cut it down with a hacksaw, cleaned up with a steel file, and epoxied the front sight back on. The inner barrel had to be cut down to all of 6" just to get the muzzle velocity below 400fps, and that was a bit more involved.
-
Very nice RC, mind sharing the technique?
-
Forgot to post this when I finished it. Technically it's not WW2, but I didn't see where else it would fit. This is a WE M712 carbine with the barrel significantly shortened, stock slightly shortened, a vintage Weaver K3 scope fitted, and the externals refinished. I also rebuilt the hop-up adjustment to use a grub screw rather than the original, finicky system.

It's one of these: That one's a Madbull but everyone under the sun makes them. It's the same as a propane fill adapter, just thicker materials and (I think) threaded differently.
-
I got the chance to test. Regular CO2 adapters seem to work much better than the APS one, since they can actually seal on the fill valve O-ring, whereas the APS one has a step that prevents it from sealing if the O-ring is low/thin enough. I wonder if maybe the issue was destroying the O-rings with excessive pressure, but it feels like you'd have to press real hard to do that. The disadvantage to the non-APS fill adapter is needing to unscrew the hulls to fill, but I load hulls separately from the shells anyways so that's not a huge deal for me. With a dollop of heavy silicone oil on the f
-
That's a weird explanation. You can't overpressurize a volume of CO2, if it contains any liquid it's always at vapor pressure. Well, I'll withhold judgment until I get the chance to live fire them.
-
I got the smart shell stems I ordered and converted all my shells over to the new system, and they all seem to really spew CO2 during filling. Is that normal behavior, or do I need to lubricate the O-rings more or something else entirely?
-
Wastelander- a gas-operated, semi-auto APS shell shotgun feeding from Saiga magazines, and with interchangeable barrel length. Full build log here.
-
Does APS sell parts to convert original shells to smart shells, or do I need to bite the bullet and buy whole new shells if I don't want to deal with the charging armature anymore?
-
They're almost exactly the same price as the Maruzen shells, but seem to have a lot more metal in their construction. I don't think we're going to see any shotgun system have much cheaper shells unless one that uses actual shotgun hulls comes to market.
-
The Maruzens can do that already, just replace the stock gas tank with an external line. The 870s then need a stronger hammer spring and the 1100s need a replacement extractor, but after those modifications you're good to go for 9 BBs per shot.
-
Am I missing something here? At 0:09 it looks like the hulls are the same as the current ones. They certainly don't appear to have inner barrels, which would be the only thing precluding you from using them to shoot random stuff.
-
So on the one hand, having a gun that works like the real thing is pretty cool, and gas-in-shell means no worrying about keeping the gun gassed. Putting the gas in the gun seems like a step backwards in that respect. And, of course, I can't convert non-APS guns to use APS shells if the shell isn't a self-contained system. On the other hand, the old Maruzen M870s could get dozens of shots on a single fill, and CO2 is much more efficient. My Wingun revolvers can fire 6 BBs at close to 300FPS and do about a hundred shots on a single CO2 cartridge, so I don't think 30-50 is completely out of t

Yes, I apologize for derailing the thread. I will start a new topic under Project Suggestions.

Had a look at the APM50s online, but I can't find their actual dimensions, so I suspect they're probably too long. I'd really like to build a Walker or Dragoon and intend to make a build log, I just need to figure out the best method first.
-
I wouldn't trust a Denix, not just from a safety perspective but functionally, as their build quality makes old CYMA pot metal look like CNCed steel by comparison. I'm not sure if they're fully-functioning in the first place (I suspect not), but even if they are, I would expect the mechanism to eventually fall apart as it unfortunately did on my converted Denix side-by-side. Cylinder pawls and pot metal don't mix well. For the real Walker and Dragoon, there is a .45 LC cartridge conversion on the US market. I imagine it would work perfectly with the Brocock cartridge, but probably wouldn't
-
That's a clever idea and it would be legal, but such a design would still be able to function as an actual firearm, something that I imagine most field owners would heavily frown upon. I'm thinking the most viable solution might be to gut the gas system from my Wingun SAA and transplant it, but then that also requires transplanting the grip frame to accommodate the CO2 cartridge. I think it's doable, but not nearly as straightforward.
-
Thanks for the comprehensive reply, Cesare. I had this idea bouncing around in my head to take a black powder Colt Walker kit and rebuild it for airsoft use, and CO2 shells a la the APS shotguns would have made it a fairly straightforward job. Guess I'll have to keep looking.
