So ive decided to build my first lower here recently and picked up a spikes receiver to build. My question is, what type of "kit"would be recommended? Ive looked at just going with spikes, maybe psa, but I just wanted to know what some of yall use. Im not looking at the top or bottom of the line, just somthing that is middle of the road for now. Any trigger suggestions? Ive been looking at the geissele triggers, and they are pretty pricey so anything eles comparable. Ive got a 223 wylde upper im wanting to put this on also. Anyways any input would be great! Im lookin forward to it.
