survivalshop Posted October 27, 2014 Report Share Posted October 27, 2014 I have a Black thorne 308 upper and it was very agravating to get it up and running properly . I changed the springs in the extractor and ejector (both were very soft ) and put a new extractor from another bolt head (with an oring over the spring)and it works fine now .The chamber is cut too short so i have to set the shoulder back about .005 more than the die will go so that took grinding the bottom of the die off . Because of this i cant use factory loaded ammo. Re-Barrel or have the chamber reamed , if indeed too short of chamber . How did it head space ?
