My AR has the Bushmaster "Dissipator" upper, which is too heavy. It has a 16" heavy barrel with mid-length gas system, and a second unused gas block/front sight post. Local smith says if you turn the barrel down between the real gas block and chamber, and between the fake gas block and the real one, the rifle will be made "wildly inaccurate." What do y'all think?
