Good quality product - JP Enterprises Enhanced Bolt Assembly Group

JP Enterprises has a great reputation for quality products. The one issue I have seen people complain about is the looseness of the gas rings. From what I can tell this is normal. The gas ring is a precision piece that is just the right size. It does not scrape the Bolt Carrier internals as do conventional rings. So if you do a conventional gas ring check procedure it will immediately appear to be a failure. They say these rings will not wear out, unlike the traditional rings that scrape. We'll see.
