New M4 - what to lubricate? (if anything)


Recommended Posts

Just purchased an M4.


Should I lubricate right out of the box?


Likewise, how often should I lubricate?


The manual indicates that the only oil to use is the Benelli branded lube. Is this correct?


What is recommended?

Don't lube the pistons or ARGO system at all unless you like a lot of smoke. You should grease the hammer and disconnector hooks. Heavy lube on the BCG rails. Moderate on the bolt itself and where the tail of the BCG link. Light surface coating on interior of receiver and on the body of the BCG.


Metal surfaces should receive a light dry to the touch coating.
