He does 2 rails down, and then 2 more. Right before engraving some bullet casings.

Hell yeah, that's great progress! One of the earlier designs when spanky was around involved a custom front rail loosely based on the g26 rails. Except the bottom part was scalloped to allow for part of the trigger guard to fold under it. There was an issue with those rails bending inward and causing issues with cycling. I made some prototypes of the frame that used the rails from the lonewolf 80% design and passed it off before taking a break of on 3d2a work. Not sure what happened after that but this is excellent news.
Its a team that was doing research on building an open-source surveillance UAV. They developed an optical sensor suite, some pretty cool low-profile quadcopter blades, and a DIY battery pack.
It would certainly go hard with the continued testing of my Granite frame. "we have mp7 at home"
Oh hey! that worked with markdown syntax!
I haven't tried a direct url gif, yet. I also didn't see anything around the text editor that indicated it could be done with something like giphy/tenor.
No doubt. I remember the original beta over on the DD rocket chat getting good traction initially but just repeatedly fizzled out. Did you guys finally solve for the front rails collapsing?
I think this is going to be my next build, it's just too cool.
I'm insanely curious about how PPA-CF holds up as a suppressor. It seems like an ideal option.
After catching up on the TX22 FRT, I'm convinced this same thing could work for the PSA Rock since it uses almost an identical fire-control-group with the firing-pin safety requiring a similar part to interact with the trigger and the slide (shown for the TX22 on the left, and the PSA Rock on the right). Is anyone working on it? I picked up an extra one this year so I may work on it myself if nobody else is.
The upside of the design on the Rock is that the disconnector is actuated by the rails of the slide instead of the internal surface. There's a small pin that extends out and sits below the bottom of the slide rails and pops up with the disconnector. This should reduce wear and tear of the slide the way it's seen on the TX22.
This would also be sick as a lever-action.
The best time was yesterday. The second best time is today.
Do:
- Invest in a good filament drier, one that will go up to 70c
- I personally recommend picking up a really good set of picks and a quality hobby knife. Sometimes supports are stubborn and are hard to remove from some tighter spots with just a pair of pliers.
- Actively work on fine-tuning the profiles for each filament after you have dried it. You can go a long way on the default orca/superslicer/bambuslicer profiles for PLA, but ultimately no 2 spools are alike so get used to printing calibration prints and updating your slicer settings accordingly.
- As others may have mentioned, do some other projects before diving into actually printing a firearm frame. You have built 80% frames, which is great experience for troubleshooting fitment. Now imagine working out tolerance stacking issues with your printer, filament, and parts all at once.
- If you decide to ask for help: post pictures and/or videos along with describing the problem, things you've tried that didn't work, and include your print settings.
- If you want to participate in beta-testing: be extremely detailed about your testing and feedback on the process for the creator.
Don't:
- Print nylon/abs in an unventilated space
- Try to fire frames that weren't printed according to the README documents.
- Force parts together if the fitment isn't more or less effortless. It puts extra strain on the parts and will lead to more failures of the prints.

That's perfect. I have the OEM fire control already modeled and was just looking at the geometry for where the trigger bar interacts with the sear and the disconnector. I'll definitely give this a dry run and see how it goes.
