Mossberg 930 Autoloader Cleaning/Maintenance

Re: Does Mossberg fire their guns prior to shipping?

Thanks for the replies. I went to the shop and asked them about it. They say none of their guns are fired before being sold. Customers are not allowed to shoot prior to purchase. I talked with one of the managers and he said almost all manufacturers fire a weapon prior to shipping to insure they operate properly. Ok, I can buy that. But man was my new one dirty. We'll see how well it works tomorrow if i get a chance to heas to our club's range.
 
Re: Does Mossberg fire their guns prior to shipping?

My 590a1 was absolutely filthy when I took it out of the box.

It looked like carbon fouling, but it was more likely some sort of residue from the parkerizing process.
 
Re: Does Mossberg fire their guns prior to shipping?

I never thought about the actual manufacturing processes. Could be something like that too!

Could be but the barrel was filthy, the gas seals filthy, the action had imprints of the shells and primers. I absolutley sure it was test fired several times before shipping.

BTW, I shot it yesterday. Ran thru a box of Wallyworld Winchester trap loads...2 3/4, 100 fps, #7 1/2...ran flawlessly...quite nicer on the shoulder than the 500, which I brought along as a comparison. Think I got the "fail-to-eject" problem with the 500 figured out. Scotch Brite the chamber...worked wonders...
 
Re: Does Mossberg fire their guns prior to shipping?

Good to see she's runnin well for ya.

My A1 was dirtier on the outside than in. It had definitely been test fired, but looked like they'd dumped soot all over it before shipping it out...
 
The most effective oil I have tried is Ultra Lube. It can cycle much faster now...8 shots in 1.5 seconds!
I have tried a dozen different types of lube and none quite do it as well as Ultra Lube. Made in the USA.
 
Need to cycle faster for 3 gun

Hey guys, has anyone drilled their gas ports on the 930 SPX to make it cycle faster. I am lookin for some extra speed so I can smoke the others in the next 3 Gun.
 
Re: Need to cycle faster for 3 gun

Welcome to the forums.

I've not theard of anyone doing this. Would this type of mod violate a rule somehwere regarding what you can and cannot modify?

I would be skeptical about doing this. The operation of a gun is an exercise in balance. Introducing more pressure into the gas system might not yield the results you expect. It may damage parts and/or cause quite the opposite result.

I don't really know, just throwing some thoughts out there.
 
Re: Need to cycle faster for 3 gun

I have not heard of anyone doing such a mod to a Mossberg 930 but I would be interested in hearing more.
 
These are fantastic vids! Thank you for posting them!!

Hi 12G

Just a quick note that Ultra Lube may turn hard and gum things up if it's left for a while, which means that you may have to clean and lube your gun again prior to going out. I can definitely see using Ultra Lube as a "day of" lube to make things run real smooth, but for all my guns I use Ballistol for lube and corrosion prevention and they are ready to go even after a few months of non-use (it really sad when they don't get used for a few months).

Check out the discussion on http://forums.1911forum.com/showthread.php?t=374407
 
Hey thanks for that, I dont know how Ultra Lube goes when left for so long, haha I dont think I could cope with not shooting every weekend. I will leave one of my 930's in the back of the safe for 6 months and see what happens.
But when you think about it, if it does turn to glue over a year or two, maybe I am not paying attention to my shooter as much as I should. When it's cleaned and re lubed it is so slick it could be seen as an advantage over the other guys who dont think out side the box. We have a 3 gun every 4 weeks and I helped a wayward soul fix his 930 that was jamming...a little Ultra Lube on it and he was smokin. Call me crazy but I'm gona keep using it, any second I can save in a competition is worth it.
 
Re: 930 Gas Piston Cleaning

Hi, I just bought the Mossberg 930 Roadblocker edition. I love it as I also owned a Mossberg 500 Roadblocker.

I was wanting to figure out how I can modify and shorten the gas piston in the rear stock of the weapon.
I am using this shotgun for bear protection as I live in Alaska, and I want to bring down the length. I would really like to get it small enough to use some type of ATI forward folding stock.
Or make the gas roc flexible somehow.

Does ANYONE have any information of modification to the rear rod/piston, and a allowable length it can be shortened?

Cheers,
-Thom in Alaska
 
Re: 930 Gas Piston Cleaning

Sorry Spaz, but if you ask this question in the Mossberg 500 section, you will definately get a better response. Good luck with them bears!

Re: 930 Gas Piston Cleaning

Welcome aboard spaz907!

I'm not aware of any successful modification to the buffer tube on the 930 platform. Mesa Tactical is working on an Urbino Stock for the 930 that works around the existing buffer tube and will reduce the LOP to 12-1/2". Until it hits the market, we're pretty much stuck with what we've got. Any modification to the rear buffer tube and you run the risk of making the entire weapon inoperative...
 
Re: Need to cycle faster for 3 gun

Had a bit of a think about it, I will increase the gas port size by 5% and reduce the mass of the bolt assy by 10%. I will compare the performance before and after with the same ammo. No mods to the spring, that will be factory.

Paul I'm not asking about a mossberg 500, I'm asking about the gas system in the mossberg 930.
 
Re: 930 Gas Piston Cleaning

LOL. Yea, I got that after our "On-the-ball" moderator replied back to you. Sorry about that. But he's right. There is no mod known at this time that would allow what you want to do. But the design right now has the link extending into the return spring plunger down the tube through the stock as the means to return the slide assy. I think that the demand and cost to redesign this assembly will prevent this mod from ever being commercially viable.

Re: 930 Gas Piston Cleaning

What about the possibility of a one time modification, rather than a commercial mod.

I need my weapon small for hiking in Alaska, and is rather not have a pump.
 
Re: 930 Gas Piston Cleaning

Excellent posts Raven and Seascout. You have to do the maintenance to continue shooting well!!

I understand what you're trying to accomplish, but please understand that the modification you're talking about has simply not been made possible at this point. Not by Mossberg, any aftermarket specialist, or any of our members.

Even minor modification or out of spec parts in the forward gas system can cause complete failure of the weapon. What you're inquiring about is a complete overhaul of the rear buffer system. Changing the length of the buffer tube would require changing the specs of almost every moving part from there forward to compensate for the decrease in buffer distance. I wish we had better news for you, but it's just not an option on your weapon...
