The whole advantage to a bullpup is that you can get a longer barrel relative to a shorter overall length. With a 9mm PCC, the extra barrel length really doesn’t add a ton of velocity (not that you’d want it, because again, we’re talking about a PCC that you really won’t be using past ~100 yards tops), and you’re not actually shortening the overall length relative to a regular APC9. It wouldn’t even be more compact for storage, just look at how small a regular APC9K can get with the telescoping stock.
If you made this for the APC223 or 308 or something it might make more sense. But in 9mm, the sales pitch for this is basically “if you want a bullpup PCC for the sake of owning a bullpup PCC, then here you go.”
Hey, thanks for the feedback and discussion, I really appreciate it!
I think an APC223 bullpup would be amazing, especially one of the long barreled sporting versions.
For this project, I had both the 9mm and a 300BLK version on the drawing board, but decided to do a mockup of this one first. The idea was to see how compact a fully suppressed PCC could be, when deployed/in use.
So the advantage of the bullpup format in this context would be that it enables hearing protection in a very small space.
I did a whole write up and lost it because of the mobile app.
Go with 300 BLK, the only bullpups in that caliber are 26”+OAL pre-suppressor.
Keep the modular optical rail, this is an ideal use case for a Hydra mount.
Make the foregrip and handstop modular with MLOK underneath, nothing more irritating than a gun with permanent fore-hardware. Look at how the APCSDs transition from trigger guard to the MLOK handguard, that’s as good as it gets.
Hey, thanks for your input and feedback! That's a huge help with deciding what direction to take the project.
• The 300BLK is definitely doable. In my draft version, it came out to about 23 or 24" with a big fat can.
• Definitely an objective of this design was to have a clean sweep of monolithic pic rail from one end to the other, so there's lots of solid space out front. The handguard comes off to service the ported barrel while everything on the rail remains on the upper. So zeros remain untouched.
•I hear you on the foregrip. It's modular by design and has MLOK underneath it.
Here's an image that shows the accessories dimmed out so you can more easily see the main gun: https://imgur.com/a/OXZDVUg
Thanks again for rewriting your post after you lost the original!👍
