$129.95 Norinco 780 Homeland Security 12ga 14" Barrel

After reading this thread I consider myself quite lucky, my 780 had no problems feeding and extracting right out of the box. It took long enough but I finally got out today to find out if she goes boom. I put 60 shells through it with virtually no issues, I had some minor extraction issues but putting some oomph into the pump action seemed to prevent that (it didn't want to hook the shell unless I really slammed her in). I had that issue twice I think, and I had one feeding issue that cleared itself up when I pumped it again. She still functions as well as she did before putting 60 shells through her, and frankly I consider this shotgun to be relatively problem free considering it's not rare for domestics to have the same issues on occasion. I'm extremely happy, for $130 I feel this is an amazing bang for my buck
 
uh oh

I did..

Honest, it was for the sake of science and, 20+ years ago. I'd just bought m'self a shiny, new mossy500. My brother, about a week later, came home with a black plastic "knock off" for half the price.

His was a Maverick...turned out then (just like now) when the 'Mav hit the shelves, it's "intercompatibilty" with the 500 had to be figured out...no 'net then either. Time has shown the 'Mav worthy of continued production. Also demonstrated that, his trigger group (cross bolt safety?) was preferable to me (tang safe on the '500)

Someone must have did a complete comparison of the hp9 and the 870 at some point too.(other than Norinco Production team...lol)
 
Well I have to eat my words a bit, that little rail that folks have been finding bent was arrow straight on mine at first...but not anymore. Just took it apart for a thorough cleaning and noticed it's bent and breaking away from the reciever. Not a big issue as far as I'm concerned, I'll bend it back up and weld or braze the bottom (what metal are these things made of anyway?). But for your average Joe I would consider this a big issue, another 60 shells or so and that thing could easily bust right off.
 
Hmmmm......

It looks like CGN to the rescue again. I'm still waiting on Canada Post, but it's becoming more evident as I read the posts that without this site my gamble would probably be a complete loss, or end up as a disarmed donation to a firearms instructor (if it can reliably eject dummy rounds, lol!). The prospect of fixing the gun up into a reliable shooter through the help of these posts does make for an interesting wintertime project, and it's nice to see these guns being put to use.
 
I had bought two of these from frontier a couple years ago. The first one would not eject. Sent back to frontier. The replacement would fire without touching the trigger, just cycling the action.

So be careful with this gun. Load it and cycle it downrange in case it discharges.
 
Ok just came back from the range. It did have a little bit of a cycling problem.
It seems like the extractor either doesn't seem to be able to get a good grip on the empty hull to pull it out, the empty hull is jammed (unlikely) or the extractor is just weak.
 
Fired mine with 3" high brass goose loads on Saturday night. The fireball was about 3 feet across and yellow like the sun. Recoil was excessive. I am thankful I've already reproduced, as I think the damn thing may have jolted something loose.

Question - would anyone who bought a parts gun be willing to part with a firing pin? Can anyone compare the firing pin to one for the 870 and tell me if they're compatible?

Played with mine some more today, what a poorly made POS. Such a pain to reassemble, nothing fits quite right. I strongly caution anyone with one of these to regularly check the condition of that short ledge the pump rail rides on, mine is in very bad shape, I would not doubt it could potentially break right off.
 
Finally shot mine. First shot failed to eject, but after i pushed the spent cartridge out the shotty ran fine, I'll probably take it apart and polish a few more things up for a smoother action. I fired 20 rnds with no problems, it does prefer to be cycled hard.

I'm happy.
 
So I received mine on Monday and I have to say am very happy with it.

I took her apart and cleaned off the oil/grease. I took some sandpaper and an emery board to any rough/sharp edges. Two places that needed TLC were the mag tube where it meets the action and the stock. The inside edge of the tube was a little sharp and was catching the shell before it fully cleared the tube. Five minutes attention there, back together and she runs great. I have run the action dozens of times using dummy shells in the mag and she runs great - releases clean and loads into the chamber perfectly. And she goes click every time I give her a squeeze.

The stock is definitely a weak point - mine wasn't even solidly mated to the action. I took it apart and tightened it up while the trigger assembly was out and I learned why. Rough points on the stock meant it could be mated tightly, but then the trigger group was pushed forward OR mounted loose with a trigger in place. Another five minutes with a dremel and sanding drum and the offending material was gone and she is now tight as a drum with the trigger mated properly. I'm planning on replacing the stock anyway, but it is more than serviceable for my current needs

I certainly won't invest any real money in this gun, but I have to say for the price paid, it is well worth the dollars.
 
If you guys are finding she sticks after the shot it coulf be due to brass and plastic exspansion, take a little fine sandpaper on a 5/8 dowel and work it around in there to polish off the chamber, works great after!
 
I finally took mine out this morning and had some mixed results.

The first box fired fine with a few cases of hard extraction shooting Winchester Super Target loads.

The second box of shells had me hitting alot better after getting used to the barrel lengthy, hitting around 18 clays from just behind the trap house. The last two shots couldn't extract further than half way out of the chamber however and required taking the barrel off to remove the casings.

Luckily the RO was familiar with 870s and slightly bent the foreend rails to get them straightened out. He thought some extra grease on the rails and brass based shells might be all that she needs to keep functioning. It did cycle a good deal more smoothly as well.

I'll try her out again soon with a box of AA loads to see if the brass base helps with extraction (I think working the rails hard when extracting shells might tend to bend them) and if she works okay with them wll be happy. Perhaps I'll shoot a few slugs just to see where she prints. With a three round plug, she'd be a great grouse gun during autumn hikes.

PS. I didn't take her apart for a thorough cleaning, smoothing over beforehand but might do that later. Any pointers on the main spots to work over (including what tools people use) or main spots to grease would be appreciated.
 
I got one of these a little while ago

took awhile to get

the mag tube is welded in crooked, so the barrel points off to the side

SFRC isn't answering emails, so I am thinking I should just put a bar in it, and bend it JUUSSSTTTT enought that the barrel points straight.

as for deburring, many years ago I bought a Mossy500. it was VERY rough. I took it apart and deburred everything. That helped.
When I bought my second one, I did it FIRST

then, when I bought one of those IMI Timberwolfs, same thing... wouldn't cycle at all. took it apart, and deburred... problem solved.

once I get a chance to, I'll check this 780 over and see what needs deburring.

Has anyone made up a parts list that shows compatible parts from better guns to replace the soft, breakage prone parts?
