Absolutely. One drop of CLP or whatever your preferred lubricant is in each vent hole. Just don't put so much oil in there that you're getting sprayed with it on each shot.
This is a discussion on AR-15 bolt carrier lube question within the Long Gun Maintenance, Cleaning and Gunsmithing forums, part of the Long Guns category; is it necessary to add oil in the 2 holes on the side of the bolt carrier group?...
is it necessary to add oil in the 2 holes on the side of the bolt carrier group?
Just oil the bolt that's all that is needed.
Ive heard that high temp axel grease sparingly on the bolt rings spurs and the four guide channels on the bolt carrier works better than oil in heavy shooting? never done it but there are people that swear buy it! Thoughts?
I use CLP on the gas rings(just a drop) and a drop in the vent holes on the side. I use a little bit of wheel bearing grease on the cam pin groove in the bolt carrier and on the bolt lugs unless it's really cold weather.
CLP works, it has a dual role of solvent and lubricant. It does not clean like a good solvent, does not lube like a good quality lubricant. But is seems to work, there are better lubricants, and greases.
I use Shooter’s Choice products FP-10 and Shooter’s Choice grease.

Necessary? No. Advisable? occasionally.

Shooters Choice red grease though.
