Anyone running one of these? Any feedback on how they perform?

Thinking about getting one as a do it all upper rather than a bunch of different uppers, but haven't heard much about how well they are working with the aftermarket barrels...

Hard to believe no one has replied to this one yet.  I know this has been talked about.  I've even seriously considered buying the LMT and the Spikes barrels but $$$ is in short supply.



Maybe you need to put this thread in a different sub-form - the AR-15 Pistons Forum or AR Discussion one...dunno.

I am also kind of surprised... II may put this in the tacked MRP thread in the uppers forum...
