I just got a pair of these off of eBay for $98. Very similar or the same upper as my mountain extremes, minus the rand. They’re significantly lighter and quite stiff. Anyone hunt in these?? Don’t see why not but curious to hear.
I have a 270 Win Tikka barrel that’s threaded 9/16 at 22”. There’s an adapter up to 5/8” that’s been thread locked on. I can’t tell you anything about shoulder size but I can tell you the barrel now has over 950 rounds on it suppressed without issue.
