Hey there everyone! I'm interested in getting your input on a bolt carrier group. I want decent quality without spending too much. I was looking into either: Fail Zero's BCG http://www.brownells.com/.aspx/pid=27448/Product/AR-15-BOLT-CARRIER-GROUP DPMS Phosphate Coated BCG http://www.cheaperthandirt.com/ARR117-7.html?ingb=Y Can you guys recommend me which to get? Or another BCG of equal or lesser price?
