One more weird note, I have also wondered about guns that have handguards like a Steyr AUG, if an enlarged trigger guard was shaped so that it would provide a good gripping surface, would that make an SBR with it an "Any other weapon"?

Hi, I was contemplating the nauseating minutia of ATF pistol regulations. Specifically I was wondering about the foregrip laws which say that a "pistol" may not have a vertical foregrip. I have two questions here: 1) Does this mean only 90 degree grips, or is it more vague and the guys...

I was more thinking in terms of some of the longer-cased cartridges that could work in a revolver rifle. maybe something like .460 S&W Magnum.

If I have a revolving rifle, are there any revolve-compatible cartridges that would be capable of hunting deer-sized game out to 300 yds. or less without significant MPBR loss? I am referring to straight-walled cases which do not setback in the chambers of revolvers, but I want one that can be...

Hmm so what I am getting from this is that this idea for using non-mechanical means to cycle and/or lock and or/fire a gun has very limited practical application due to the already exceedingly good completely mechanical firearm designs. The idea looks like it would only have practical...

Funny you should mention just timing the unlock because that's where the drawings I posted come from. The original gun I designed uses a spring loaded weight which is released at the same time as the striker to delay the unlocking by the "flight" time of the weight. the spring then acts on the...

I drew up a CAD model of the idea in a more advanced rifle pattern that I already had mostly drawn. I see this being something that is easier to manufacture at home, the majority of components would get printed or made some other simple way, and the bolt would need to be purchased or...

Wow I am really happy to see that we have some conversation going here because I have been thinking about this a lot lately. To clarify, I reviewed my ideas and I think that I can only go so far in explaining what I had in mind without possibly drifting into the territory of demonstrating how...

Hear me out here..what do you think if a solenoid actuated action in a firearm. Basically instead if gas pressure or recoil, the action is timed from an electronic trigger pull and actuated by a magnetic solenoid of sorts. This would primarily have two advantages and some disadvantages. Pros...

I was just wondering the other day, why don't rifles use a tapered collet setup to mount barrels into actions? If this method is secure and concentric enough for the tooling used to make the barrel on a lathe, then why no use something like an ER 25 collet geometry to hold the barrel shank? I...

I just found this from the creator of the 22TCM mentioning the .30 Carbine: “Since Armscor is also a large manufacturer of ammunition, (most people don’t realize that) I had a huge amount of resources at hand. I originally started out smaller with a .30 Carbine case and a 9mm-platform pistol...

This Is exactly the process i was thinking about if I were to use existing brass, this is how the 22 TCM is made, but I think you could compete more with 9mm, .40 S&W, ect. by using some 7mm caliber bullet like .308. Based on what I am hearing it sounds like I want a "30 TCM"

Those would be really cool to see numbers on too, but .357 being based on the 10mm auto has a wider base diameter than 9mm and 7.62 Tok is just barely less, and I think having an increased magazine capacity is one of the big selling points for what I am imagining. I often hear people complain...

I actually am familiar with the 7.5 F, however I determined that the overall length was too great and the base too wide. It's nearly 1.4 inches long, which I think could negatively impact pistol ergonomics, and it also has a base diameter of 0.425 which gives you less capacity that 9mm. The...

I am interested in a cartridge imaginary or possibly one that already exists which falls in-between 5.7x28 and 9mm par. What I mean by that is a cartridge which utilizes a slightly smaller diameter bullet and casing to increase velocity and magazine capacity, and that has a greater overall...
