I bought a gen one in 308 when they first came out. Over all I've been happy with it. One of the reasons I bought it was its compatibility for AR grips, handguards, and stocks. And I have tried different angled grips, 3 different stocks before settling on a magpul PRS gen3 (but I did have to cut an inch off of it to get a comfortable length of pull due to the added length of the folding mechanism), and swapped the forend with the new gen 3 m-lok forend (mostly to get rid of the top rail which had sharp edges). I lowered the trigger weight as much as it would go and added a Heathen muzzle break.
Pros: accurate, modular, takes AICS pattern mag, lots of aftermarket parts and accessories, prefit easy swap barrels (I have never done this myself but there are lots of videos online).
Cons: It's heavy. with scope (3-16 x 44, 30mm tube), rings, fully loaded 5 round mag mine tips the scales at about 15 1/2 lbs), Bolt is rough, and there were some sharp edges on the original hand guard that I cut my hands on several times
Depending on what you are doing the weight can be a good or bad thing. I've used mine for hunting and have taken a couple of deer and a moose with it but its a little heavy for hauling through the woods. If you are using it as a range gun the weight helps with recoil.
Would I buy another one? It's hard to say. when I bought mine there were no other options available in that price range. Since then the price of them has gone up $500-$700 and there are a lot of other options available.
