Sorry to here about your trouble,Ive had good service from Ruger other than being told different things by different employee's.A guy on another forum works for Ruger,and speaks highly of the pride put into their other guns.But claims Ruger uses different tooling on the production line for the Mini-14.He claims Ruger could not afford to buy all new tooling and make every gun to the exact specs and sale the gun for the price range its in.I believe the guy because he knows it all about Ruger Products?Hope things work out for ya!
Best!!
