"I also tamed the bark of these guns with some baffles from a 5 usd Aliexpress oil filter in the shroud. Plus installed an SSG and an Altaros reg in my P12."
A word of warning here....I also ordered one of these and waited a few weeks. Then I got a call from a Homeland Security Special Agent who advised me that importing these items is illegal and they are being confiscated and destroyed by U.S. Customs.
If you live in the U.S., and don't want your name tagged in the Homeland Security database as a "person of interest"...then I most strongly suggest you purchase your modification parts locally.
