One thing i really like about the Bighorn and other vendors is that I can use the savage thread vs remmy thread. I have all the tools for the savage, but none for the remmy. The only other requirement for barrel thread would be the machined in recoil lug. I know the APR doesn't have it, but I think the solid 1 piece receiver/lug makes a huge difference. IE, one less thing I have to screw around with...
