Short and sweet. Anyone heard of hidesertdog barrels? I'm looking at threaded bull barrel and they offer the thread lenght in .475 for 5$ more.Whats the big deal on free floating. Looks to be hard on reciever. Stock, I am looking at Boyd Blaster, mainly because I am not sure about free float. Gunsmith suggested mounting optics and stock to barrrel, sound good? General plinking and squirrel/rabbit hunting. Thanks.
