Currently trying to design a brass deflector/ dust cover combo for the WK 180 series, this is a rough V1 design that will drill and tap into the side of the receiver, the dust cover I plan on using hasn't arrived yet for measurements but I plan on making 2 for myself once fully designed, let me know your thoughts, feel free to be harsh, I can take it lol

Or just leave the rifle alone? It doesn't need a case deflector. I'm a lefty and the lack of case deflector isn't an issue for me. If you are right handed, you are looking for a problem to solve.

Not overly interested in drilling holes into the receiver.

Why bother even posting if you are not going to add anything of value to the conversation?


Your design seems interesting, are you using a standard AR15 dust cover? It should be simple enough to mount into your piece but getting it to function properly may be a different story

AR10 Dust cover, a standard AR-15 dust cover is slightly too small to cover the entire opening on the 180, well, by slightly I mean it's basically the same size depending on tolerances, Ar10 cover is slightly bigger giving me more room to work with. I have a couple ideas floating around in my head on how to get the cover to operate properly that don't involve machining a new BCG, it would be much easier to just redesign the entire upper and BCG if I had the CAD files for them, but I don't have the time to measure an existing upper, let alone the money or skill to do so properly lol

What material are you looking to use? I bet if you made a 3D print you could prototype its effectiveness using good two-sided tape (or even epoxy) to mount it instead of tapping it straight away. Would significantly lower the installation difficulty too!

That is my plan, probably looking at 8-10months by the time the prototypes are tweaked and the first aluminum one is finished
 
seems odd to me that you are making a dust cover for the opening already blocked by the bolt carrier, and leaving that big charging handle gap on the other side?
 
I would like to see how it turns out as well. I think tapping/drilling is not a favorable solution. Perhaps, you could look at intergrading it into the handguard some way? Kind of similar to how the S&J hardward Turknelli bolt release tab intergrates.

Thanks for the feedback, unfortunately I don't think that sort of design would work properly with a dust cover, I considered making another model that has "arms" like the 3d printed TNA brass deflector that attaches to the pic-rail on top, but unless I make it two pieces (which I don't believe will be a reliable solution) the machining price would almost triple as would material cost to make it a solid piece, I've also considered making the V1-"tape edition" where there are no mounting holes and no dust cover, basically the render I posted but with holes removed that only functions as a Brass Deflector, it would have a "pocket" on the the receiver side that would allow some sort of 3M tape to be added and the unit still remain flush (I've seen people 3d print brass deflectors and stick them on with 3M tape to some success).

Since there are a few people like yourself that aren't really keen on drilling and tapping, and someone else mentioned that the bolt does basically block the chamber, I'll redesign this model to only be a brass deflector attached by some heavy-duty 3M tape or epoxy. But I believe the only way to have a brass deflector/dust cover combo function reliably and correctly would be to drill and tap, which I will remain working on.

Well, here's the progress, the dust cover came in, now I'm just figuring out and semi-finalizing how this whole thing will function


(yes I know the hinge area isn't cut out yet lol)

Looks good! If you'd want to minimize installation I'd get a Strike Industries AR-15 dust cover as it's a self-contained unit - no need to screw around with rods and springs, and designing the piece to accept it. I think Magpul just released a similar product, they call it their Enhanced Ejection Port Cover.

If you are looking to simplify production I would also modify the deflector stub to be its own screw-on unit similar to what ATRS has done with the Modern Sporter (pic here). I assume it would be cheaper that way.
