>>30339426

Hah, if you see them hit the market then get in touch.

>>30339461

Yup, I'm thinking that's the best idea pitched so far, especially because it's something we could market. If we go that way then a suppressor would definitely be the next logical step.

>>30339039
M16A1 clones that are proper and not these abortions niggers are putting out. You can compete with colt and Troy and if your price is right it won't even be a competition. Also modern Lugers and c96.

>>30339448
>>30339461
I read it on some forum that (maybe qc10) was experimenting with a 10mm at carbine. They made it gas operated though, the general consensus from the forum was that 10mm too hot for simple blowback and even that it will work that way you were on the hairy edge of safety.
>Probably ar15.com

>>30339805
That's all for the engineer to figure out. The concept is solid though.

Makes the 10mm carbine gas operated roller lock like a ptr

Aw, you mad? Where's the guy who was going to make a bunch of vintage stuff? Or 80% stuff? I'd love a new production AR-180 or a Krag-Jorgensen carbine in .30-30 but I'm being realistic in that it'll never come from someone posting on /k/, looking for ideas.

>>30340396

Hey I'm being honest here, the most likey scenario is that we continue making ARs and suppressors for LE and odds and ends for ourselves. I've got one trigger idea for the civilian market that we're going to try selling and if I can find something else that we can profitably produce that no one else is then it's a win/win. The projects you're referencing seem like they were biting off a lot more than they could chew.

VIntage repros would take too much effort for recalibrating machinery, and consumers would just complain that 'muh fit-n-finish' just aint tha same.
the neoAR180's are the serbu 15 or 16 upper, sig's mcx, and a couple other things, I'm honestly surprised Armalite hasent tried to bring back the 180 though. nobody is gonna bring back anything in chambered in 30-30, its rimmed, and its old. fuck it. 30-06 though...

>>30339261

not really doable since a straight blowback 9mm action would need to be far too heavy to fit into a mark III receiver

I prefer the FNH gas piston system much more than any piston retrofit, plus I've got a major hard on for the ambidextrous-ness of the SCAR upper.
The upper receiver of the FNH SCAR is the only part you can't buy on its own. You can buy literally every other component.

That makes me moist
I really wishould the AR platform had slot style barrel assemblies that allow for quick change of barrels on a single upper.
Like being able to swap the barrel and bolt or BCG and the mag-well and have gone from 5.56NATO to 7.62NATO in 5 minutes or less and not have to re-do headspace and timing.
Kinda like the ARAK 21 and Late gen SCAR where you pull 2 pins to swap the barrel and swap the bolt and you're good to hook. Slap in a SCAR 16 mag and rock small caliber from using 308 a few minutes prior all with hands and maybe a punch.

It ain't .40

>>30340879
Lol, and if it's a change that allows for an AR15/10 lower receiver and mags to literally mate right up with no other adapting parts then it's technically a new upper that FNH cannot legally come after you guys for.
Especially if it's an 80% where you've gotta machine out the ejector port, barrel vent ports, and a few bolt holes and tap them and the take down pin holes.
80% that they can't do shit about. And I can tell you I'd buy the shit out of it.
Especially if you guys made an adapter to mate an AR barrel to the FNH SCAR upper as its not a thread in upper but a Trunon that uses a pair of pins to mate them together for quicker barrel replacement and caliber change...

>>30340879
>>30340924
Also would be significantly cheaper that way and more friendly.
Instead of $1000+ on a barrel assembly and $500 for a semi lower, and not even being able to purchase a SCAR upper....
>>30340913
I haven't seen it, I'll look up shot show 16 on YouTube but so far the only stuff I know about is SCAR lowers that adapt the AR pistol grip and magazines. No uppers for SCAR at all

>>30340599
This, but in 54r and/or .308. Ideally it wouldn't require proprietary mags, but the ability to go from 5.56 to .30 cal would be it worth it.

Make a literal shitload of these: Hamilton No. 7 bicycle rifles.

They were chambered in .22lr, and were made almost exclusively out of cast aluminum, steel rod, and brass, all of which was then nickel plated.

Shorten the firing pin to 2" and replace the rest of the length with barrel, and you'll have a 16.5" barrel. Use 3/8" steel rod bent on a mandrel to make the stocks and the barrel support, and use .22 barrel liners as the barrels (totally doable if you make a billet steel breech/chamber portion, that'll handle the real pressure problems).

Stamped steel sights, cheap as shit packaging and minimal shit to go wrong would make this an interesting firearm to bring to market.

If you could find a fast ass way to make these and sell em for $59.99 or something, they'd be killer.

Well we're already an 07 with a title II SOT which is the whole reason my stepdad was brought into this in the first place so that's not a problem. I'm really struggling to understand why people would want a turnbolt instead of a straight pull, it's also not something we could market to government contracts which currently are our only source of income. Anything that we make strictly for the civilian market would have to have relatively low R&D costs which a turnbolt wouldn't.

and it's crap, frankly. And it's much too expensive, and hard to find.

If one could make a gun that retails at $49.99, you'd more than HALVE the price of the Chiappa. You'd also be selling the worlds cheapest new firearm.

The Model 27 was the cheapest rifle available in America in the 1930's. A stamped steel and wood firearm, it was a simple, functional, and cute firearm, it was purchased and used by boys of all ages for a long time.

It also was so cheap that it was used as a "prize" for farmers: in every twenty 100lb bags of chicken feed, there was a chance you'd get a Hamilton Model 27 in the bottom.

But if you want to see how dam simple this thing is, look at the picture: you have four major components in the receiver besides the almost solid piece of a bolt: the one pece trigger, the one piece hammer, the spring that serves them both, and the ejector/locking bar assembly.

Beef up the design where it needs to be, and you'd have a hell of a

Possibly not unique, but at least rare:

10mm AR.
.45 AR.
7.62x25 AR.

Literally the 3 things I want to add to my collection (not for muh collectors's val-you, but just for fun shooting) but can't find any for a decent price

Guy at a local gunshow last weekend had a vz2008 that he fucking spray-painted black selling for $800 cuz its "tactical"

Pederson device dropin for common boltguns

I'd like to see a modern K31 type hunting rifle chambered in .308. 7.5x55 Swiss is almost 7.62x51mm already, so it can be done.

20 gauge revolver with a 7in barrel and like a sort of Sig brace or one of those weird UK legal handgun lengtheners, or to be honest just a piece of metal to fit the curvature of an arm with some Velcro straps. Instant outdoors and backwoods hit for animals and hunting, just keep the OAL long enough to be a firearm and not a shotgun and the barrel length won't matter

Quickloader for a wheel gun that can be used multiple times.
Twist one time and the next set of rounds cycles down via spring to take its place. Had an idea for one of these a while back, but could never get it to work right because I'm not an engineer.

Magazines for hard to find weapons.

One I own: Steyr GB. It's a stamped magazine, would not be hard to replicate, but current factory magazines go for $100-200 apiece and are hard to find.

If someone made a reproduction magazine and they worked, I'd happily pay $35-50 per.

Also hi cap glock 10mm mags so i can stop converting G21 magazines.

>new production AR-180
Real talk, new production AR-180 uppers would be THE SHIT

Nodak Spud already makes lowers and part kits.

Last I heard there was someone working on them, but the biggest problem was figuring out the black witchcraft that allowed Armalite to fix the barrel extension in the receiver cheaply

>>30343880
Sr25 mags would be perfect for the .308 variant. The 54r would be the one with the proprietary mags, unless it cold be engineered to take vepr mags or something.

>>30339039
A semi automatic rifle chambered in .44 or.357 magnum just for shits and giggles. And make sure it gets mags with decent capacity, unlike the Ruger Deerfield Carbine
