This 880 was acquired in March of this year. It has been shot a good bit since then and I have been watching videos and reading post on how to disassemble and reseal, and do a couple mods.
My first impression had been this gun had not been into, that it was stock. All screws were not scratched or fouled and all looked to be in great condition.
I took it apart today and checked over the barrel, gave it a good cleaning. To my surprise the tape mod had been done but with duct tape but it was in bad shape. Also, the shroud has rifled barrel stamped on it but I see no rifling after cleaning. Several pellets were pushed thru and no marks were made on them and very little resistance was felt .

Question: Has the barrel been swapped it the past or have BB's removed the lands?
Are barrels still available for the older all metal 880?

I contacted Daisy for parts diagram, parts list and price sheet. Received reply that parts for the older guns had been all sold to Gun Smiths and got a list of four to contact. Baker Air was one and also T-Mac.

Who do you guys use when needing these older parts?
The barrel is troubling to me. If I cant find a rifled barrel that is a drop in fit I may not even put it back together.

Thanks for any and all replys.

The shrouds interchange from 1972 to the present, plus they're still available from Daisy, so there's a chance the shroud doesn't match the gun it's on. Or the barrel may not match the rest of the gun. Unfortunately if the shroud's originality cannot be trusted, with the exception of the very early guns and the plastic receiver guns there's no easy way to tell whether the gun came with a smoothbore or rifled barrel. Some VBs were stamped with a date but that's not across the board.

Shooting BBs will not remove the rifling. It is very fine, shallow rifling- think 'microgroove'- but it'll still be there after shooting BBs for many years. The current production barrels are a press fit but they can be removed from the VB. The problem with using them is they are a little shorter and they lack the TP hole and the groove made to locate the barrel to VB. I've never used a new barrel in an old style gun but it looks like the length wouldn't be an issue because there's enough engagement with the front sight/barrel plug. But the other machining ops would need to be done. The new barrel/trigger group/VB assemblies are $12 from Daisy. The trigger group is also still available along with a few other odds and ends that still fit the older guns. Barring that, the GTA classifieds, ebay, GB or AA classifieds are where I would look for parts or a parts gun.

Just a suggestion, but why not reassemble the gun so you can use it and then if you happen across a rifled barrel you can swap it in.

Thank you Mark. My barrel does remove from the valve body and has a .157" wide by .035" deep notch for locating and clamping in place. It is completly smooth but shoots targets at 10 meters very accurately. Once I get the proper reseal kit with cups, rings and such I probably will put it together.

I wonder if I should replace the entire valve body? It shoots good up to 8 pumps. If I pump 10 times the report sounds funny, kind of a swooshing sound and fps is off. Not sure where the problems for that.
I did a tissue test by covering the load port and get blow back there.
Will the new style with the o-ring work with the metal receivers?

Take a look at Stony's "Most Asked Questions" up top and you'll read he bought one he thought was a smooth bore... but the rifling was plugged up with Copper,and green. A thorough cleaning "might" get you some rifling...

I cleaned it pretty good and it only had black oil looking patches , no green or copper. It shines like chrome now but not the faintest hint of rifling.

The new guts will fit the old metal receiver with some work. How much work depends on how old the receiver is. In my experience, metal receivers with the big rear stock screw on the RH side and the loading port open on both sides are easiest, next are the RH screw with RH only loading opening. They still will need some clearancing, like for the new type O-ringed bolt probe. The new bolt has to be used with the new style VB/trigger/barrel assembly, else you will get a ton of blow-by.

Some links that will help you decide:

Good info, thank you. I spoke with Tony from T-Mac by phone today, live 3 miles from him. He has repair parts for 880 in his shop and I am to meet him Friday. Hope he has what I need.

cobalt327 · « **Reply #7 on:** August 28, 2019, 06:56:02 PM »

Dang, how convenient is THAT! The cup seals are the buggers, everything else is reasonable.

mr007s · « **Reply #8 on:** August 28, 2019, 06:59:42 PM »

YEP! The cup seals are what I really hope he has, and a valve assembly.

That and a couple O-rings and it should shoot like new.

FWIW, I found a way to rebuild the old screw in exhaust valve. Daisy sells the O-rings and the little "C" clip retainer so all I do is reface the valve tip and touch up the seat if needed, replace the rings and so far that's worked for me. But simply replacing with a new valve sure is the expedient way!

JG Airguns has a pretty good selection of 880 parts. You can start on this page: https://www.jgairguns.biz/catalog/index.php?cPath=78_186_197&sort=2a&page=1

Page four has the seal kits. There is a pretty good description of what year the kits fit once you click on the item. Page 4 here: https://www.jgairguns.biz/catalog/index.php?cPath=78_186_197&sort=2a&page=4

I buy most of my 880 parts from JG, but here is another parts vendor (I have not purchased from him). https://www.daisy880.net/?page_id=6

Is there a special tool or trick for removing the clip and being able to reuse it?

Thanks for the links Dennis. I am checking them out tonight.

I carefully use a pair of needle nose and put one jaw against the stem and the other at the split to get them off. I go over the top, the poor drawing tries to show this. Same thing to reinstall but put the jaw opposite the split. They can go flying so be careful. I used to do operations like that and safety ball/spring installation inside a big-A ziplock to catch flying parts.

Now this can roughen up the end of the stem. If that happens carefully dress the raised areas and polish with some 600 grip wet or dry paper and it'll be fine. But do this before you pull the stem through the valve body so it doesn't get scored.

FWIW if you can find a barrel for a model 881 it is rifled and should swap right onto your 880 VB.

I don't know for sure if that above link will fit your gun.

Perhaps someone else can tell.

Yes, that's the idea. Might use masking tape on the side that will contact the stem, just for insurance.

Dennis, unfortunately that's the new style like Daisy is currently selling for $12. It's what would be used if someone wanted to swap out the old style setup. Replacement/maintenance parts like seals, exh. valves, etc. are uber cheap. It also shows what I was talking about regarding date stamping- it was made in 2017. Earlier VB are sometimes stamped with an ink stamp.

To find an early type rifled barrel in a parts gun, look for a 1980 through 1989 model 880 having a LOT NO with the:

1st position- any letter
2nd position- number 0 through 9
