Hi!
I was wondering what people used to lube a semi-auto shotgun? Where metal to metal surfaces come in contact with each other (other than the gas system), a bit of oil would seem to be ok.

But what about the magtube, spring that goes over the magtube, gas piston and gas-piston ring on the barrel. I've read and watched videos that suggestion plenty of things. I've oiled them, but I'm starting to think I probably should of left them with no lube at all.

Cheers!

I have a Beretta 391. It work best with a light oil lubing on the mag tube (spring and sleeve move on it) and transfer bars in the receiver.

It depends on the model of shotgun. Different procedures for different guns... some need lubricant, some can be damaged with lubricant.

Most of the time an owners manual will state what to do.

What do you have?

I have a Charles Daly 601 in 20ga. Didn't want to go full blown into a semi before knowing for sure I like 'em. It's such a fun shotgun to shoot! Selling my 12ga o/u...I liked it *that* much.

Well for me it depends on the time of year . summer time I use white lithium grease on the action rails and a light oil on other moving parts . when I prep my waterfowl gun for cold weather it gets light oil on the action rails and many of the other moving parts get run dry . example trigger group firing pin and bolt to carrier contact surface .
 
I just run a light oil on pretty much everything. If I am field hunting I’ll wipe it down after and light oil again. If I am on the marsh I’ll do a good break down and re-oil. Never really pay attention to rain, snow, or sunshine. Just clean it up and re apply.

I use a 20 ga charles daly semi for waterfowl out of my kayak. Its seen rain and snow and plenty of wet times. I come home take it apart spray g96 wipe down and reassemble. Never an issue with function or rust. I too like the gun considering it cost as much as the tax on my a400 20ga lol
 
Guntech is spot on , the owners manual ( download if you don't have one) will tell you what to do. My Beretta A303 recommends light oil on the bolt and transfer bars but the gas system is to be run dry or it will gum up ,other systems may require other maintenance methods.

I checked the manual last night and the details are scarse at best.

Depends on the time of year and whether or not your storing or shooting. I put a light oil on all metal parts before storing. If/when hunting or range day I wipe off all the oil and pretty much run it dry, especially in cold weather for most of my guns. Unless you use a solvent you won't get all the oil off anyway and I find just wiping off the oil (unless it's gummy from longer term storage which requires a good clean) leaves enough lubricant for the shooting applications I do. When finished shooting, clean and lightly oil again.
 
For My Beretta A350, I usually clean all the internals really good with rem-oil. Then put just a drop of oil on the bolt guide rails and where the bolt slides; for the mag tube rail I use dry teflon lube.
 
Regular oils in the gas system will bake into a hard carbon that becomes difficult to remove. Use any kind of synthetic lube on the piston and magazine tube as they resist heat much better. I've had great luck with BreakFree CLP on gas systems. After four or eight rounds of trap/skeet, literally just wipe off the magazine tube with a rag in a single pass, re-spray, done.

I will agree 100% . the carbon stays suspended in the hi temp oil and wipes clean . re lube and go again .
