Mossberg 702 Breakdown

Is there anyone else out there who owns the 89 dollar Wal Mart special Mossberg 702 Plinkster?

"So," Said I, as a naieve soul, "I've never taken my .22 apart for a thorough cleaning and it hasn't been touched for over a year. I think tonight I'll squint at that little diagram in the back of the manual, take it apart, and clean it."

And I did. The Mossberg 702 has an elegantly simple design (which might explain why it always works, no matter what I do to it) but boy, is it ever a pain to disassemble. Unscrew the stock screws, drive out two pins holding the upper reciever to the trigger assembly, gently pull down to discover that bolt tension is holding the reciever together, pull back bolt to relieve tension, separate halves of the reciever, sproing! There goes the recoil spring and guide.

It is truly amazing the amount of grit, ook, and gunk that can accumulate in the inner workings of a firearm that a resonable soul would think had absolutely nothing to do with the actual act of handling the lead or burning the powder. I think I blacked up about six rags and spent about half a bottle of No. 7 on that thing.

Anyway, here's the rub: Is there some sort of trick to getting the stupid thing back together? Eventually, I did. The problem lies in the recoil spring and guide, the latter of which has to butt up against a little block sticking out of the inside of the top of the upper reciever. This is well and dandy, but there's no way to hold it there, slip the rod and spring into the bolt, compress it, and then stick it in there. You need three hands for that. If you just slip the spring into the hole in the bolt and try to sort of angle the rod in there afterwards you can't, because either the rod or the bolt is too long (take your pick) and it binds up. Eventually I got it by doing the above but poking it with the handle of my screwdriver until the guide rod went in there, but I had to bend the spring considerably to get that to work and I wonder just how much violence that does to it.

Is there a 'proper' way to strip and assemble this rifle, or is it just an all-around PITA?

I bought one of these Mossberg Plinkster 702 and have taken it apart and put it back together 3 times in the two days that I have owned it. It is a bit of a test getting it back together but it is worth it in the pay off when the rifle is finally given a good cleaning. It is a .22 LR ammo only gun, I found out the hard way by running about a 150 rnds of L ammo and getting a jam on every third cartridge. Dummy me. Its sucks up the Hypervelocity stuff something awesome and is just a great inexpensive "Plinkster". I love this gun. Its was $116 including tax with a scope at Dick's. In two days I have put about 300 rnds through it. Again I love this rifle. Super light, super accurate, super fun, super inexpensive, and it justs looks so prudee!

hope this helps
My experience in Takedown, reassembly of the 702 or 7022

With the Mossberg Plinkster 702 or CBC 7022, the
blade ejector rides in a slot in the bolt.
The blade ejector is attached to the action housing
that includes the trigger and firing mechanism.
For disassembly, the bolt must be locked to the rear
to be clear of the ejector.

Remove the magazine if in place.
Work the bolt and visually inspect the firing chamber
for an overlooked or stuck round.
Make sure the gun is unloaded.

Press the safety to on.

The barreled action is removed from the stock by
removing two screws.

Pull the bolt handle back and lock the bolt open
by pushing the handle in.

Drift out the two pins that hold the action
housing to the receiver. Pull the action
housing down off the receiver.

Hold the receiver upside down in the left hand,
insert the right index finger in front of the bolt face,
pull the bolt up to about a 20 to 30 degree angle,
grasp the sides of the bolt with thumb and middle finger
and move the bolt forward as smoothly and quickly as
possible to avoid kinking the recoil spring.

The bolt handle will fall out of the receiver.

To reassemble,

Place the recoil spring guide in its seat in the reciver,

Press the bolt down at about the same angle used in disassembly,
index finger right hand on bolt face.
Avoid kinking the recoil spring and press the bolt down til
end of the recoil spring guide rod is inside the bolt.
Then, left hand holding the bolt handle in ejection port,
swing the bolt down onto the bolt handle.

Hold the bolt back by the handle, right thumb on bottom
of bolt, remove the right index finger from between the
bolt face and the barrel breech. Ease the bolt forward.

Then pull the bolt back and lock it in the open position.
Re-insert the action housing (make sure the plastic bolt
buffer is in the correct position).

Replace the pins to hold the action housing to the receiver.

While 7022 has a lot in common with the Marlin 70 or 795,
it has differences, too. Compared with the Marlin M60,
the bolt removal (except for the ejector) is similar but
different.

Below is the link to the owners manual. I have removed the trigger in order to remove the bolt. Make sure that the hammer is cocked and the plastic buffer (white piece that lays in the rear of the receiver behind the bolt) is lined-up to allow the trigger pins to be re-installed.

Putting the trigger assembly back in is a bit like Tetris. If you have the manual, you can figure out by looking at the diagram which way the buffer faces.

A word of advice though, do yourself a favor and DO NOT take the trigger assembly itself apart. I made that mistake, and it was a PITA to put back together. Save yourself the time and just clean it as best you can without taking it apart. Won't hurt it any.

Does anyone know if Marlin Model 70 magazines will work in a Mossberg 702?

I cannot find mags for a Mossberg 702 anywhere, and they look similar.

I do not know if the Marlin mag will work on the Mossberg. I know that all the Walmarts around here carry the 702 mags and so does Cabelas.

None of my local walmarts still carry guns or magazines, and we don't have a Cabelas around here close and their website has had them as "backordered" for months.

Sorry to resurrect an old thread but I just made that mistake, too, of taking it down to a detail strip. It looked real cruddy and crappy down there and spraying it wasn't working, and I couldn't get the q-tips in deep enough. So I took it down which included the trigger group. If anyone can at least point me in the right direction to figure this out. It's getting late and I had to stop but I have been on this episode for the last three hours trying to get it back together.

I do have access to a quality gunsmith, but I like being able to takedown all my weapons down to the details with confidence. Therefore, learning to do it correctly or getting the right tools is a better outcome for me then the standard 'take it to the 'smith' or send it to Mossberg.
