I saw that, but I do not know if the US market is receptive to it's $325 price. EC's is $225, and the ATS gives you 3 options for $185, 200, and 225 and uses your choice of MBs. I am not sure if you are the tuner's owner/builder; if so, good luck. Cheers!The without warning tmb also needs no barrel work. Installs like any normal self timing muzzle brake.
That’s all the Winchester BOSS is. You do seem to need index marks and some kind of set screw to hold position. I wonder if the weight is important?I think I'll have our lathe guy turn me one tomorrow. They don't appear to be anything more than weight that's screwed in/out to change the harmonics.
