Re: Clocking YHM
Mine is titanium QD and stops in the same notch on the ratchet every time. So it is always clocked to the same position. I don't know if turning it to a different spot would affect it or not, but mine doesn't seem to have much of an effect on POI anyway. Just a little over 1" @ 100 yds.
I'm using it on an AR 308 and all my AR15's. I have trouble with the cold bore shot with or without the suppressor. It's just unpredictable that way. So, since all my shooting is on a range for fun anyway, I just disregard the first half dozen rounds and go ahead and get it hot. It settles down and is consistent after that.
The blank portion of the blast baffle is at the point where the "slanted washers" are closest to the blast baffle. I think they did this to prevent a gas jet from ramping across the path of the bullet, even though the bullet may be long gone by the time that happened. This is just my theory, I'm sure there's a much more complicated explanation for the absence of holes at that spot. I'm just very impressed that such a simple baffle design can be so effective as well as simple.
