Have you noticed any issues with wear on your can? I have a pistol inbound (will sbr of course) and want to put a 7.62 SDN-6 on it. AAC specifically states, "Centerfire rifle caliber silencers are not warranted for use on barrels less than 10” in length. 762-SDN-6 and SR7 warranted on barrels as short as 7.5” when used wth 300 AAC BLACKOUT or 5.56mm." It's not my first suppressor, but it is the first time I will use one on an SBR, just wondering if there are any unique issues I should be aware of before hand.
