Well its regulator. We all know what it does... Enough said there.
But. here are some aspects of it.
It's very consitant, +/-5 even better sometimes
has two holes for mounting the fittings. So use one, and cap it off or throw a gauge on.
Easy to mantain. Just wipe it down, lube, and reassemble
Now, looks may be a downside, it loooks hideous on some guns, it just does. But on others, it works fine. But overall, performance>looks
Conclusion:
Great item, well built.
Bob Long wouldn't throw these stock on millions of Timmies if it were crap now, would he??
