the reciever itself doesnt matter really. Spikes, stag, any tier 2 or 1 will be good. DPMS and lower... 90% chance of being fine... but with the supieror arms and spikes deals at AIM, id get one of those.
If you want a 2 stage or match 1 stage trigger, it may be cheaper to get a combo but IDK for sure. gissele is supposed to be coming out with a 3gun 1stage match trigger soon(the noveske shooting team has them to try out). To be honest, id get a cheaper lower(does not really matter) and put one of them in there. But thats just my $.02.

Are you a lefty.....if not you would be hard pressed to find a lower better than a lmt w. sopmod and lmt tube with a lmt 2 stage.
this may be a good deal, but i dont know the price. the reciever itself is about $100, the sopmod is about $200, comfy, but if im spending that much, i want a club-foot style(like the modstock or emod). tubes are about $25. I have never heard about the lmt 2stage so if your looking into it, i suggest you get some reviews and price it out to find what kind of deal they have. FWIW, im pretty sure trident knows his shit so definitely look into it, but price everything out before you purchase.
