LRBHO is easily removed with 3 screws for competition shooters. Use with Lead Star Arms bolt carrier groups, these were tested during development and proven to work reliably for the last round bolt hold open function.

    I have used many of the Lead Star receivers and have yet to be disappointed. They look and perform great. When building my first one over 3 years ago many folks said I would have problems with and get dirty from with a skeletonized receivers. I have yet to have problems with either. Highly recommend for performane that will catch the eyes of others.
