Hey guys!
Ive been lurking around for a while here, im in the process of building a blowback operated 300 on the AR platform with a 9mm bolt and some other
little goodies.
My question is, have any of you attempted anything like this on any platform?
This will be a dedicated subsonic gun as to keep the pressures in the 25,000 psi range.
I have a feeling this puppy will be pretty cool once the EJECTOR is figured out.
Mike
