Best Deal On BCG
I was very impressed with this Chrome Lined Phosphate C158 BCG. I used my pin gauges and did several measurements on the gas key, bolt tail, bolt shoulder support and bolt tail run. All measured to TDP specifications and was very tights. This BCG is built with very high quality standards.
