I’ve got nothing against the idea of a mostly printed dedicated ar22 barrel. I’ve got to go against the grain and ask: Is there a reason you’re opting for the traditional ar22barrel (im assuming its gonna be the typical profile) over a carbon fiber Proto-barrel? You’d only need the larger diameter of the two “required carbon fiber tubes” when making one from a chaszel barrel. The best part is its infinitely easier to remove the liner if you mess up or want repurpose the liner for a different project ( versus sticking prints it in a corrugated cardboard box to cook it with a Heatgun). If you want to use any muzzle devices it has coarse thread adapter that is much easier to deal with than the finer stuff like: 1/2-28, 5/8-24 when printed from PLA+/pro. If its something you just feel like doing or designing then go for it I wouldn’t mind seeing other barrel profile copies or even entirely new ones. However when taking into Consideration $20-ish (generally speaking if there’s two brands with seemingly identical options the one priced slightly higher usually will have a better finish) buys enough material to make at-least two (16"long) and as many as 6(5.5"long) (remember chaszel liners only use the 1x25x23x420mm tube in the BOM ) nothing else comes to mind that can elevate your project’s looks and (most often) performance for such a small investment in capital and time.

What brand bolt might you be using? I’ve seen a great deal of printed cmmg style dedicated .22 bcgs that appear to be of different origins of design floating around odysee however I’ve never seen any proof of life.

I can’t ever stay up late enough to ever get on there when your hosting the classes live. Is there any way to access them after the fact?

Good luck I’ve been searching for the same thing and have never been able to find a dd19 with the thumb depression AND rail.

There’s exponentially more vile concepts and products coming out of California. What’s the point of removing guns from California when the assholes who wish to misuse them still remain.

Yeah I didn’t consider that could be an infinite money glitch if you knew a few owners of convenience stores.

Never built a bobcat but I’ve built 3 arks of different calibers and 1 2.0 in 300 black out. I ended up disassembling them to use the parts for other projects. Only the 22lr wasn’t ridiculously heavy, if you have any issues/made any mistakes disassembling it is a time consuming hassle due to the threaded rods as spines design however this allows for a study result. Once you get them together correctly they’re not any better or worse of an AR platform functionally just a different manual of arms (in my opinion). If you decide on the ark the charging handle is a must for an enjoyable experience.

I’ve always wanted to build a bobcat. What’s prevented me was finding a suitable bcg that fit the recommendations in the guide so I wouldn’t have to modify it any more than absolutely necessary to make it compatible with the project. If you decide on the bobcat I’d like to see what bolt carrier you decide on.

Pretty cool if you ignore the tape securing the two magazines together 🤣. Please spend the 20 minutes it takes to design a side stack base plate so the neighbors won’t describe you as an airsoft playing crackhead when they see you bringing this to the car. Next time you see them in their yard it they’ll be handing you donated 6mm bbs and bulk packs of clear lighters homeless people and teenagers use.

yeah heres the url…https://odysee.com/@Diamorphine:b/UMP-11-9-retracting-stock.:d

its gonna be a little bit wobbly in its current form so dont expect to be breaking any distance or accuracy records with the help from this guy.

Now that forbiddencode has released the 3 part ergonomic AR grip I’m building another one that’s gonna be white with red trim base.

It’s the ump 11/9. I referred to it as “the ump” in the second sentence I figured that would be enough context. It’s arguably the cheapest Mac/AR project you can get into as a beginner. 100 bucks for the bolt 70 ish for the barrel/trunnion 25 for the trigger/hammer and 30 for the plate (more like 5 but the minimum order is 30 bucks).

Yes. It’s a hodge podge of different people’s stuff. The projectile dysfunction for all but the barrel and pistol grip. The grip is the (I think?) laff dynamics v2 storage grip and the barrel is grixxly prints ramset barrels for pd.

I wouldn’t go as far to say you’re a life saver. But you certainly saved me a lot of frustration! Thanks.

That’s awesome. I need more work surfaces and shelving. I’m defaulting to the floor like a crackhead cause the only workspace is a 4x1.5 feet computer desk that ends up being a “catch all” for clutter.

I second the motion to inquiry. I need this in my life!

Id love a real photo of the firing pin with it’s new printed parts installed before inserting it in the slide. I looked at the included step but only the printed parts are represented. Am I correct in assuming the spring needs to be moved so it then pushes the firing pin in the direction opposite of it’s normal iteration?

Good catch. I was searching the part number and the provided part name so that discrepancy was flying right over my head.

In the BOM of the pdf the Spring loaded bearing is listed twice with the same parts number but it says only one is required in each entry. I just wanna confirm this is a typo and I’m not over looking something.
