Ok, so I believe I have decided on getting a DPMS AP4 in 308.
1. Will a standard Ar15 2-stage trigger work in it? I have an RRA NM 2-stage I would like to put in it.
2. I have a good deal on a rifle length quad-rail freefloat tube. I am wondering will the .308 freefloat tube work on a .223 rifle or vice-versa? If for some reason I changed my mind about getting the ap4, it would be nice to know I could still find a place for the tube.
Whats a good source for finding these rifles?
your RRA trigger will work
308 AR tubes will not work on AR15's or vis a vis
