Remington will soon be selling the a variant of the Model 700 SPS Tactical that includes a 5/8-24 threaded muzzle. This will allow it to accept AAC and other 5/8-24 threaded flash hiders, brakes and suppressors. A thread protector is included with the rifle. Its MSRP is $757.
I have been very surprised that Remington has not been more active in marketing AAC suppressors to civilians.
