I had an aluminum rod guide from Vudoo, it had a handy retention point built into it so it would lock in place like the
bolt does. I don't think the polymer universal guide has that feature. I really like metal products, but I feel that
a polymer like PTFE, UHMW, etc is the best choice for a bore guide. I like the poly Vudoo mags better than the 7075 as well.
All 21 of my V22 poly mags functioned flawlessly in a MDT LSS Gen 2 chassis. My rods are the simple J. Dewey and Hoppes Elite
with ball bearing handles. I have bore guides for every rifle I have because it makes cleaning a simple, quick task. My guides
are almost all Possum Hollow. They are very inexpensive, they will build me one to suit some bizzarro gun I bought and all of the
polymers are about the same in this application.
