barrel length & muzzle brakes how do they effect sound and performance?

wow  real minefield for you guys cant help but wonder if one of your manufactures couldnt just make something out of a combustable/fragile (stiff card or thin brittle plastic) material that could never effectively be used on a firearm without causing total failure and get it approved.but one of your prosecutors would probably argue that harry potter could cast a spell on it and make it indestructible

He uses an interference fit and is one of the few shops anywhere that does it correctly.  Basically it involves heating one item and cooling the other and fitting them together.(notmal hand tools won't usually make it fit - think heavy machinery)    It might as well be one piece of metal after it cools, since they are pressing on each other with thousands of pounds of friction and and attempt to heat one heats the other.  IIRC, he said that he spent almost a decade sending devices to to be tested before he figured out how to get it right. 

He's not cheap, but he can do it right.  Oh, there's a thread on GTA about the rifles that won Gold in the recent Olympics being loaned by him and a couple of GTA members. (including his own personal gun) Silly cutting edge barrels and regulation that simply out-shoots every other design.  Hard core American machining and technical expertise that stomped the German and Russian designs.

its not cheap but worth it if you live in an overzealous area
