While the ARMS rail would not have been my first choice when spec'ing together a premium grade rifle, or my second choice, or third, or...
It is still a good rail system. Most of the parts & accessories used on this offering from BM seem to be very good quality. But the railed gasblock has got to go! I would advise him to replace it with a LaRue gasblock, and send it off to ADCO to drill & pin it in place.
