The LH RAR stock does not have the removable plate for the modular mag well. Did not know the bolts were notched.
Shot my RAR LH 223 yesterday the factory mags are awful, they feed like 1.5 year old that does like its food.
I’m not sure if we’re using the same mags but my son’s lh 223 American feeds like shat through a goose with the factory polymer rotary magazine. Maybe we got lucky?
