As we mentioned on the SHOOTING GALLERY episode on AAC's suppressor match, "silencers" were added to the 1934 Act at the last minute to "fight poaching." Suppressors stayed on the list because of endless Hollywood frenzy about "assassins' weapons." The idea of federally controlling an object that at its low end has the technological sophistication of a quart pop bottle or a car muffler is on its face ludicrous.
Secondly, suppressors are the solution for increasingly urbanized areas, where the opposition to recreational shooting is more based on noise than anything else. Suppressors also reduce recoil and flash, impediments to becoming a better shooter. Recently one of the federal law enforcement training centers, faced with OSHA-mandated demands to either cut the number of students, double the number of instructors or a third option took the third "making guns quieter."
A former LEO friend of mine recently told me about his "house AR," a short-barreled carbine fitted with an Aimpoint Micro, a SureFire suppressor, a "big honkin' flashlight" and sighted in at 35 feet. Heck of a good idea! If I was to do this (and I'm definitely thinking about it!), I might go with either the Crimson Trace laser/white light vertical foregrip or the Insight long-gun MX6 laser/white light.
