JAKL9 drum magazine compatibility.
Is it true that the Magpul PMAG 50D CZ is not compatible with the JAKL 9 lower receiver? I just read that on one review on the MagShack website.

You're welcome.
Anybody know if the super safety, Atrius, or Flex 3MR work in a JAKL9 lower?
This will thread into the bolt release and make it way easier to manipulate. M4×6mm is the size you want. https://a.co/d/0j9Ylsnz

This is a funny story. Hired the gunsmith at the store/ range to assemble the upper. After doing a couple, I've decided it's really not my favorite thing to do.
I asked him if he would test fire and tune the adjustable gas block since it's just easier to access without the handguard. He looked at me and said "no. I'll just close it all the way and let you do it yourself. How's that sound?" I was just like "alright, whatever."
Lol. It functioned flawlessly. Dude had jokes. I'm never assembling my own upper again.
Parts list:
Resilient “Stacy’s Mom” suppressor
FCD Stoner 63 KeyMo mount and HUB adapter
FN 20" chrome-lined, button-rifled barrel
Midwest Industries quad rail
Thunder Tactical carry-handle upper
Rear sight: manufacturer unknown; assembled and installed by yours truly
Microbest chrome BCG
BCM non-ambidextrous, small-latch charging handle — this started as an A2-clone-ish build, so I wanted it as close to mil-spec as possible while retaining BCM quality
Colt scope from Brownells
FN lower receiver and grip
LaRue lower parts kit and MBT-2S trigger
Aero Precision stock and buffer
Damage Industries chrome-silicon recoil spring — little-known brand, but incredibly smooth; it even comes wrapped like a cigar
Blue Force Gear Vickers sling in the supposedly limited-edition “choc chip” camo pattern
Missing from the photo: Streamlight ProTac 2.0
I have a $50 credit with silencer shop to SBR this. Would y'all ask for a refund, send the form, or wait?
Microbest DLC BCG. Xeno A2 style suppressor mount. Lahar suppressor. Magpul furniture. It's got a SBR stamp and a stock now.
