Is it hard to replace the current muzzle brake w/ a flash hider? Would this transition decrease the value of the gun becuse right now its new in box or should I just geta nother AR and leave this one alone?

It's not hard to get the brake off.I got mine off by knocking out the two pins that hold it on,took less then 3min to do.Some people have had em fly off while firing.I sent my upper to ADCO they threaded the barrel and installed an A2 flash hider.I had my upper back 7 days after sending it,great company,highly recomended.Good thing about the 6400C is that it has a 16" barrel and you don't have to permanently install the A2.
