Should extractor and the bolt face be lubricated? I lubricated the bolt lugs, but not the bolt face itself. No manual seems to recommend it. |
This could be good advice in an Army setting since you are dealing with 18 year olds that probably have limited experience with a gun and are scared sh_ttless by inspection so they dump half a bottle of CLP down there trying to get it clean. You have to write the book to your audience. I for one always lube the chamber/bolt face and never wipe it up before firing and have never had a problem. |
I believe it’s common knowledge in the firearms community that bores, chambers and bolt faces should be free from excessive lube before firing. I believe the reference to the Army -10 has nothing to do with age or audience, but everything to do with safety. |
Just for the record, I am referring to excessive lube. I too lube my chamber, bore and bolt face before storage to prevent corrosion. But... before firing, I run a patch through the bore, swab out the chamber and ensure the bolt face is free from lube. I can’t believe this is a topic of disagreement, when again it’s common knowledge that these areas of any weapon should be clean and clear of any EXCESSIVE lube. And I believe in this case especially the bolt face. ETA:

That's what I'm saying. You can have a guy that's been shooting since he was 6, or the guy that has never touched a gun before. The former will more likely maintain his weapon better and know how to do it. The latter not so much and may just want to pass inspection. And if you have to grab a weapon off the shelf, you have no idea who PM'd it before you. You have to write a manual to the lowest common denominator. |
I’ll agree about the writing of manuals. I’ve read enough of them in the Army to know. Regardless of the type of equipment, rifle, vehicle or aircraft, they are all basically written on a 6th grade reading level. But, the reasoning behind drying these areas of excessive lube is a safety issue. |

What are the consequences of overlubrication? I think I overlubricated the bolt and started having FTEs... faiures to eject. Now this may have been just a coincidence. I replaced the ejector and the ejector spring.. will see if that makes any difference. But I do wonder if overlubration can make it jam. |
|
My personal opinion: Excess lubrication could accelerate firing residue build up in the chamber. Excess lubrication in the barrel should be self explanatory. But I believe the major concern with excessive over lubrication of the bolt face would be headspace issue’s. ETA: In the chamber, I believe headspace issue’s could also be a concern. |

I always leave the bore, chamber and bolt wet with lube when storing. Before firing I run a swab (on a pull thru so no disassembly is required) thru the bore to remove the excess lube AND whatever dust, dirt, or schmutz the lube may have broken loose. I've seen several bores that were scarred from what I assume were dirt in the bore. BSW |
