Required to mate with rainer match barrel - JP Enterprises Enhanced Bolt Assembly Group

Robert's Review of JP Enterprises Enhanced Bolt Assembly Group
I had a Toolcraft DLC bolt that kept sticking in my Rainer match barrel. Rainer said they use the JP bolt as their reference so I bought one and problem solved. They also said not to use the special metal o-ring that comes with it. Instead, reuse the mil spec one from the old bolt.
