i own one and love it. is it decked out? no its not but i paid $800 for it and im really happy with it. had i known then what i know now would i buy it again? honestly no i wouldnt, but only to build one. if i had no build option i would most defiantly. i would use stag parts in a build and i would suggest the stag to anyone interested in buying over building.
know that you are going to have to invest in some kind of sight as soon as you purchase it. red dot, scope or rail type iron sights could be as cheap as $70 for magpul mbus to $150 for an ok red dot (i have a vortex)(primary arms is another option) scopes could cost $100-multi thousand
i for one am planning to run a 1-4x scope on my build in progress.
the stag model 3 is a fantastic rifle.
i know there werene many pros or cons but hope i helped.
I have one and I'm happy with it. Just like the other comment, it being without any sights was not a hindrance to my decision to purchase the model 3 as I know I will be dressing it up for carbine matches.
Like all the above, I love mine too. Very light and accurate. You must buy additional rails (additional cost) for the Versa Rail forearm if you want to mount, or purchase sites if you want to use open sites. I mounted a Yankee Hill Gas block sight up front, and a Magpul MBUS rear - works great.
