This is an untested beta of the SuomAR9-v1
Inspiried by DingoDaze's AR15 Suomi Drum Adapter https://odysee.com/@dingodaze9072:c/Suomi-Adaptor:e
He also has an ATRH lower for Suomi Drums https://odysee.com/@dingodaze9072:c/Ubolt-SummAR-DrummAR:c

After comparing DingoDaze model to mine, which I based off of his original adapter, his is way more polished and stronger than mine, I include a step file vs. mesh... but i don't see alot of room for improvement in his model so unless you want to take my step and copy his improvements to my model.... I wouldn't bother with mine.
Soon I will drop the files for the SD Handguards and HK Charging Handle that should work on any blowback AR.

gunCAD is dangerous. Don't ever build this, you will put your eye out.
