Excellent product-superior service

by

The BCG is very well crafted. I expect good service and longevity over time. The real story here is PA's superior customer service. The order was processed literally within one hour of my placing it and delivery was extremely fast. I continue to be amazed at PA's service.

This is just a great BCG. Excellent finish, easy to install, matched it with a WMD 16" Nitromide barrel and was placing 2" groups out to 300 yards without really trying that hard. A breeze to clean. Love it.

Ease of maintenance.

by

This was standard on another rifle I have; the carbon and crud almost fall right off. Since this upper needed one, my experience with the other rifle made this a no-brainer.
