Guys I tried everything you suggested plus some. This is what I have come up with so far!
The rifle arrived with FPJ BOLT and open primer breech plug installed. Just recieved FPJ breech plug. The FPJ bolt with FPJ breech plug works fine. The Lehigh bolt adapter and Lehigh breech plug will not close(3/4 close with or without primer). Knight open primer breech plug will close with no primer,but will not close with primer(3/4close). At this point I thank its a bolt headspace problem or just the name on the box. The knight and Lehigh breech plugs look the same side by side.
Don't think this has anything to do with the breech plug but the stock inlet is way off. A lot more space on right hand side of barrel inlet than left side?! When bolt is moved forward its forcing the safety off(bolt is moving safety to firing position!!) Also the trigger shoe(left side) is pressed against the trigger guard which is forcing Trigger safety lever to dig in to stock as well as bolt.
