i got the pmr, i was in the same situation as you..
you get a better barrel with the epiphany.. but as i had 2 barrel kits floating around i chose the pmr because of how easy the bolt comes out, how light it is and i'd heard it rips.
wich it does, considering its so cheap.
i havnt had any problems yet with the pmr, that wernt down do my clumsiness
i didnt really like the stock trigger but i found a UL trigger floating around a shop for £9 (bargain eh)
timmay a wild shot in the dark, .691 is normally stock for most?
hope you make the right choice, try go to an event and shoot them? then you can deffinately make up your mind.
