I think this is way cool, and I want one... as soon as a pistol brace (collapsible or folding) is released for it. Seems like a way fun gun to burn through my excess 22lr.

I've got these two MCX stocks to try





I'd really like to see if I could get this one to work.



Also JMAC Customs has some side folding stock options that are MCX-esque

[Last Edit: Outrider] [#6]
I found this picture which seems to show the Sig collapsible brace working (though no picture of it collapsed) so maybe there is hope for the stock. It is a bit chunky though stacking the stock on the adapter. The wheels keep turning...

ETA: Tracked down the owner and it does not collapse.

Here is a link to a rail adaptor for the CP33

REHV Arms CP33 Adaptor

Here is a link for a telescoping brace for the CP33

KelTec CP33 Telescoping Brace Adapter

These are pretty much the only ones available unless you want to 3D print your own adaptor.

Yep. Pretty sure the above photo is using the Rehv one. I'm going to snag one when they come back in stock. Figuring out a stock situation is what I'm mulling over now.

Prior to getting the Farrowtech tele brace adapter, I got one one of the Rehv Arms adapters when they first came out.  I did a fit/function test with a sig brace I had laying around.  I prefer the Farrowtech.  My OCD bothered me that the Sig Brace interface would not align with the top of the Rev Arms adapter.  If I moved the Sig Brace one more notch up, the top of the brace's picatinny interface would interfere with the CP33 charging handle.

That does mess with my OCD a little bit too. I'm just not a brace guy though. Maybe I could do a stock with Farrowtech's system.

Had mine out today again.

Great trigger, accurate and reliable.

I did have one failure to fire, followed by a mis feed in one in my 5 mags.

4 mags went 30/30 and that last mag went 28/30.

I am trying to keep that mag in mind to see if it could be mag related.

Shot some NOS Federal walmart bulk.

The CGS is for show.  I have a Sparrow that I actually use with it.  Mine has been very reliable.  About 700 rnds through it now.  Maybe a couple mag related stoppages is all.

I designed a carriage that slides into the front of the upper using the same slots that the OEM CH uses at the back.  Then a stud inserts from the side and is held with set screws.  Obviously, this requires cutting a slot into the side of the upper.  It also requires removing the upper "ears" on the barrel trunion inside, but they don't do anything so no big deal.  They're just left over from the CMR I think.

It's non-reciprocating and the handle could be mounted on either side & the whole thing works with or without the OEM CH in place.  This was is an early design I had 3D printed in aluminum.  I've since tweaked it quite a bit & I'm working on a folding handle for it as well.
