Definitley need to work on this one, lol. Worked great on my .22, but the first shot of 9mm obliterated the printed part and struck the endcap. These things are a lot of fun to play around with though!
A MCX/M7/M8-style DeAR-22 platform. Includes 16 different lower versions and two upper receiver systems. Also has some accessories like an MCX style pistol grip and flanged magwell. iFe Upper receiver includes 2 handguard lengths: long (190mm, 7.5") and short (50mm, 5.9") plus a collar that does not have an extended guard. Lower receivers that do not have full length picatinny rail are designed for the PP MCXish hinge. Rear-charging lowers are compatible with regular milspec AR15 upper receivers and charging handles.
Has 2 handguard options, but they're kinda hard to measure now, so these dimensions are from the back edge of where a barrel nut would sit: long one is 190mm (7.5") and the short one is 150mm (5.9"). Inspired by u/Miserable-Crab16's monolithic upper.
Love you guys! I'll be back at some point, and better than before. In the meantime, I just released a polymer-sheet hybrid AR9 lower that should hopefully keep you satiated for a while, lol.
Inspired by the protogen style from the furry community, but more grounded and with near-future mechanics. See 7th image for cutaway view/technical sheet.
And it sucks because the finish is so nice! It's from Sunlu and printed at their reccommended settings, but it basically turns back into powder the second you touch it. This is just from picking up the gun from the pistol grip.
I've oversized the pin holes, so very little stress is transferred to the plastic part. Of course, the plastic part still has the FCG holes and recess, so it is legally the receiver. The metal parts (side plates are identical, plus rear buffer plate) come out to only $25 on SCS (with free shipping, if you get them anodized). Should be very strong and reasonably cheap, too.
The reason I'm moving development away from the 5.56 SPC-15 is because with Glock mags and the 9mm bolt, I can use just 1 sheet per side for all pins and the rear receiver face, instead of the complex and pricey plate stack that the SPC used. Much simpler and cheaper. Unfortunately, this also means that because it's wider, the fire selector has to be custom, and the trigger pins need to be longer. Decent compromise, though.
My logic here is that a lot of energy is wasted by the coils in accelerating the projectile from 0 velocity. A hybrid propellant-electromagnetic system would solve this. I think a subsonic .22 blank like a Ramset would be quite good at giving it enough initial velocity that the coils could then use all their energy to further accelerate the projectile to a reasonable speed, rather than wasting it through high resistance when the projectile isn't moving. I also imagine a ported barrel and gas liner would be needed to prevent hot propellant gases from entering the plastic coilgun barrel. I'm not serious about building this, but I think it's an interesting idea that preserves the quiet firing of a heavy projectile that a coilgun provides, but potentially with higher muzzle velocities than a purely electromagnetic design would be able to achieve.
Are there any gauss rifle projects or development out there for capacitor gauss rifles like Arcflash's EMG-02? I haven't found anything on the interwebs. I would absolutely love to get my hands on something like this, especially to get closer to my dream of a magnetically-boosted subsonic firearm. Problem is, I have very little experience with electrical engineering and making one completely on my own would clearly be almost impossible. The EMG and all of Arcflash's other rifles are sold out and prohibitably expensive, so I'm wondering if there's any DIY development progress for similar gauss rifles out there? (i know it's not a firearm and thus not governed by the 2A, but it seems relevant)
