Default Lubrication

I've often heard that AR-15s require more lubrication than other rifles, but can's seem to find details. I'm having a 5.56/.223 Bushmaster lower being built up for me, my first AR. Can anyone enlighten me on this? My humble apologies if this has been discussed before.

I've run all of mine fairly dry. I only used a light coat of Breakfree CLP on the bolt and carrier, a light coat on the buffer and and a drop on the trigger goodies and sear.

When in doubt, consult your owner's manual, or follow the recommendations of your 'smith.

We use a type of semi-solid grease that Brett came up with on the hammer and trigger contacts and then a thing coating on the BCG.

Outside of that, a good cleaning from range use and you are good to go.

I don't think the weapon takes an "excessive" amout of anything, though that is the rumor, except for ammo.

The direct impingement gas system has a propensity to dry out the bolt carrier group faster than a gas piston system. Good dry lubes overcome this to a certain degree because there is no oil to "blow out".
It should take several hundred rounds to blow out the oil and require touch up. YMMV

Mine were so lubed it was running out the bottom the holes and anyother place (US ARMY). If I get one now I will use nothing but Wilson Combat Moly grease.

Coat the bolt and carrier, with a decent amount of lube (Slip2000, Machine Gunners Lube, Mili-Tech 1), but you do not want it driping. As previosly stated the gas burns off the lube, but if you run it dry it will devolop FTF, FTE issues in a few hundred rounds.
