i don't know about pmr's but this smart parts lubricant that I have been using has been very reliable. It is silicone based lubricant and I have been assured that it works for both the bolt and as a barrel lubricant.

Sl33k? If so, that is almost an industry standard. More companies recommend dow33 (which is what sl33k is, note that the e's are actuall 3's) than any other lubricant. The few that don't recommend dow33 usually recommend dow55 (Bob Long has long been the biggest recommender of Dow55). Dye and Smart Parts lubes are both nothing but dow33.
