Mossberg 930 Autoloader Cleaning/Maintenance

Re: Breaking in a 930WF

I just looked up Slip 2000 and they make a regular formula and another stronger formula with EWL-30 for semi automatics. It's a thicker formula it says. Don't know how that will affect cycling.
 
Re: Breaking in a 930WF

Wasn't as bad as I thought it was. I scrubbed all the parts down as much as I could with CLP then dried then lubed the rails and other metal parts I could find. I only placed a few drops on the rails. I am going to pick up some kind of different solvent where I could let the bolt parts sit for a few hours.

Are the bolt and the rails on the gun the MAIN parts that will cause cycling issues?
 
Re: Breaking in a 930WF

The cycling issues have more to do with the gas system, the gas rings in particular. Keep it clean and the bolt mechanism shouldn't be an issue...
 
Re: Breaking in a 930WF

You won't need the Limbsaver! This is one of the softest shooting guns there are! Buy 00 instead! :D
 
Re: Spring length question...

its 14-16 past the tube that is installed. cut, bend and cap. trim if you have feeding malfinctions, double feeds etc...trim 3 rings and try again until it quits....if it doesnt, then something else is going on...
 
Re: Breaking in a 930WF

I thoroughly cleaned and lubed with Frog Lube. I'll let you all know how it turns out... They really are extremely dirty out of the box aren't they?

my father used 3 in one oil for years . is there something better out there?

Fine for hunting and leisurely shooting but not up to snuff for competition or shooting multiple mags/loadings in succession. The heat will burn it off and leave you running dry.

I can get my AK smoking after only a mag or two of rapid/bump fire.

I use Slip2000. I have not used too many others as this works for me but I know there are other options.
 
Someone else may have posted a tip like this... I had a "well whats that" moment last pm. I was cleaning inside the fixed barrel assembly where the springs are. When I put everything back together I looked down at the floor and there's a small ring. Thanks to the search feature I found where it belonged. Guess my rag picked up the rough edge responsible for the scratches on my mag tube and pulled it out. Couldn't get it to go back in place for anything. Finally took a small pair of hemostats and slightly pinched ring together, locked the hemos on while ring compressed. Unlocked them in position and there it was perfect. Took the sharp edge off the end of the ring that was slightly protruding while I was at it. Hemostats have saved my but a many a time.
 
How long should a "standard" length spring be (no extension tube, just the magazine tube and it's cap)? Trying to find that information, and so far I've come up empty handed. Thanks!

I'm getting ready to strip and clean my SPX for the first time.

I have a few options for CLP and LP options, but after reading diyguy's awesome evaluation, I also added Hornady 1-shot and WD40 Special to the mix as well.

I have Hoppes #9 solvent and lube (original), BreakFree CLP, Otis O85, One-Shot, and WD40 to choose from and an assortment of brushes, bore brushes, snakes etc.

Looking for opinions on what would work best to remove all the factory grease/lube/oil, clean, lube, and protect and continue to use in the future.

I am thinking use some BF CLP to clean the mag tube, piston, and bolt/slide and a little #9 to oil. Then use the Otis system for the barrel until clean and do a final wipe with 1-shot or wd40 as a final layer of pretectant...

What do you guys think?
 
I should also add that it has been in a safe for about a year, and I do not know what the previous owner used to clean/protect it (if anything)
 
I shoot my 930 so much that I rarely actually clean the barrel interior other than to run a dry boresnake through it. I thoroughly clean he exterior of the magazine tube, piston, and gas tube interior. I wipe down and re-lube the bolt, barrel extension, and receiver interior. To clean the magazine tube, I use Flitz Metal Polish and a paper towel. The lube used on my 930 is Rand CLP as recommended by the manufacturer.

For my carry weapon, I use FrogLube.

For my 1911, I use Mobile 1 Bearing grease on the rails, slide, barrel nut, and barrel lugs. I use Mobile 1 Synthetic 75W-90 Gear Lube for the barrel link and hammer. It also supplements lubing the rails when I shooting in a match or over 100 rounds at a time.
 
^ Second that...

Thanks guys, I did read his awesome evaluation (actually I gave him props in my post above). Great info. and real world testing. After reading it, I picked up some One-Shot and WD40 Specialist.

I ended up using the Otis solvent/patches on the bore and muzzle and a little bit to clean the bolt and slide, with a small amount of #9 oil on the slide and rails, CLP on the mag tube and components, some One Shot to clean the piston and components.

This thing was filthy and caked with old grease! I went to town with a few brushes and q-tips and it cleaned up nicely. The barrel took about 13 patches (6 pulls per patch) with a brush every other pull before it came out (almost) clean. I finished it off with a few pulls with a bore snake and One-Shot.

Broke it in today, 70 rounds of a variety from 1oz slugs and 9-shot buck to birdshot, and 1145 fps low brass target.

This thing is amazing...such a nice piece - surprising low recoil and easy to reset for follow-up groups. The slugs were by dangerously fun and accurate. 10" groupings from 45 yds. right out of the chute :)

I only had one FTE, with the Hornady 00 Buck (9- shot, 1200 fps). That is also the only round that I could not fit (7) in the tube, since it is almost 1/4" longer than the rest. The rest cycled fine, ejected perfectly (out and away), good patterns/groups, even the low-vel. lightweight target loads were running great!

I had to end it early but I am eager to get back out there asap to put it through some more! Got some new stuff to add in my build thread too :D
