I am a newbie to the AR15 world. I have started out with the Spikes lower. I got a hold of the Spikes enhanced lower parts kit with an ALG combat trigger tuned by Geissele Automatics. I am starting to look at the uppers now. I think I am going for a completed upper kit. Looking at a 16", probably a middy. This will be a SHTF weapon. I will use it for a bit on the range until I build something specifically for the range. I really want this to be the best for the money style rifle (needs to be dependable). I do like the free float quad side style. I like the flip sights and will of course accessorize with a front grip, light, and some type of scope. I have looked at the Spikes LE 16 middy with 9" quad. I have also looked at the BCM but appears to be a couple hundred dollars more expensive. Any other ideas/recommendations out there? Is the BCM worth it? I am also looking at the VLTOR stocks. Decisions, Decisions!!!
