Back in November (the 20th) I submitted my paperwork and money for my AAC 762-SD Suppressor. Though it is configured for 7.62 (.308) center fire ammo, it will also quiet down my 5.56 ammo through my AR. All of my 7.62 and 5.56 rifles are set up with the AAC 51 Tooth ratchet attachment muzzle devices. The ATF cashed my check on February 1st. Projected times were 285 days from the time ATF cashed your check until the tax stamp and suppressor were available for pick up. I got a call yesterday that mine was in and could be picked up. My wife and I drove the hour to the gun shop and picked up that sweet little piece of goodness. It is a mite heavier than I expected, but not enough to affect the ability to carry the rifles for distance. Working the range all this weekend, so the can will get a workout during slack times. Will report later.
