To the op: When purchasing a trigger, it would be wise to first determine what the intended use for the rifle will be. If you'll be using it for hunting then a single stage trigger would probably be the best option. If you're planning on taking it to the range for paper punching and plinking steel then a good two stage trigger would be optimal. I use a Geissele SSA-E in my P308 and it is nothing short of superb. It has a first stage pull weight of 2.3# and a crisp second stage break at 1.2# for a total pull weight of 3.5#. It's non-adjustable which means you don't have to worry with having to re-adjust something while at the range and it's easy to install. In my opinion, and to echo what others before me have already stated, I think you should stick with POF components if you're wanting a gas piston rifle. If you'd rather have a DI setup, give the guys at G.A. Precision a call and find out what they can do for you as they have built the GAP-10 using the POF lower and upper assembly. Although the POF is made primarily of proprietary parts, I prefer the gas piston setup for several reasons of which I won't divulge because it would likely derail the topic in a piston vs DI debate.
