If it worked and it was marketable in the current airsoft Market Bastard would offer it and China would clone it. Plus these weird shaped 'bbs'' would render current mags obsolete.
Not necesserely because, the modification to do to fit mag, the real cap aspect (you couldn't switch to low cap or hi cap) that mean it could be the result of a new category of specialized (milsim) airsoft
if u look a4ound enough u'll eventually find info on here somewhere about bb's that were oval cross-section with a little tail designed for use in breach loading sniper rifles
I saw those wings bullets and happy some to see people some people try to innovate systems...Even if it's not working all the time
We will find a way.
