I have a Rhino AR10 I had a dropped my carrier and damaged the bolt face, was concerned I would not find one. Came across MWS site and ordered one was a little worried it might not me real because the price was too good. Well I was wrong it was the same high end large rear bolt and carrier. These are the best low MOA bgc for 308 ever made. I have tried other including JP and this one always shoots better in my ar10 then even the $500.00 JP I bought.
