So I got a gift card for academy for my B-day and bought a ruger ar-556 lower with it. Now im trying to decide if I want to do a dissipator or 10.5 pistol build (I like front sight posts). Its going to be my first build that goes beyond putting an upper on top of a lower. The build is going to be a semi-budget build with a PSA assembled upper. I will probably go with a fail zero BCG as I found one for 125 online (guns.deals is amazing) or aim surplus titanium bcg looks nice, but I dont know if its just flash or if it procides anything over nickel boron. Im looking for a more cost friendly charging handle than a BCM and have found strike industries extended variants for 25ish bucks. As for triggers im caught up on 3, Rugers ar trigger for 95$, rise armament cheap 140 trigger for 85, or JMT saber trigger with anti rotate pins for 85 also. I like the idea of the ruger because it would keep with the brand of the lower and include the grip. As for a LPK I dont know they seem to be everywhere and I cant decipher one from another. I don't know where to start, but I figure I could get to building and collecting parts while I try to choose between the two configurations. Any direction and or suggestions would be greatly appreciated.
