Call me a glutton of punishment but I always liked the B19 platform. It was my first and fast love affair with a handy, inexpensive break barrel. A lightweight, accurate opensight bundle of joy. Then I scoped the pos. Not one, not two, but three different branded Bewareteens before I stopped buying. Damo, Doublecrossed Man, and Chi Conned Dough.
I was beginning to feel like the Larry King of cheap break barrels.
Turns out the trigger was intentionally designed bad on these guns to hide the worse (if that's possible) pivot design.
So I hear all that's been sorted out with the Diana 250. I ask the merciful viewership (or sucker) that may have a 250 in hand to please show me some pics of the D250 pivot design and how it eliminates the tendancy for the B19 clone to group at 3-6-9-12.

I don't know who Larry King is or was. I do know things can be done to vastly improve the Crosman B19 trigger group - like replacing it with an NP2 trigger group. That said I, too, would love to see pictures of a disassembled Diana 240 pivot.

I just broke my budget and ordered a boatload of pellets and the Diana 250 package deal in 22 cal from Pyramyd because of their groundhog day sale. The rifle, scope, mount, rifle case, pellet pen and free tin of pellets for $130 minus 13% discount and free shipping? I couldn't resist that deal.
I plan to post a mini-review after it arrives and I have some time to break it in. Realistically it IS a cheap break barrel. In this package deal the actual rifle cost is close to $70. I'm hoping it will be a better than average B19 clone in birch wood stock. Probably will have some rough edges that need polishing. Cheap Crosman parts, including Nitro gas springs, should provide easy repair and upgrades IF NECESSARY,
I can tune my older B19 style Crosman triggers to work better than the NP2 trigger in my Summit Ranger. Still not convinced the NP2 trigger design is an improvement other than it is easier to factory assemble and therefore cheaper to manufacture.

Can't beat that deal Michael. You've tempted me.
-
Just come across this thread, but I thought the Diana 250 is built on the B25 platform, not the B19.

I dont' know anything about the guns you are referring to but I feel like putting a scope on some guns can totally throw off the gun's harmonics during the shooting cycle. If your gun worked better shooting with open sights, I'd recommend keeping it that way. Maybe try a peep sight if possible. Some of my guns I just stick to open or peep sights just because they seem to buck more with a scope on.

This is a B19 clone as the exploded parts diagram shows. Mine was VERY dry and twangy. I also initially did not like the way the trigger was adjusted and the simple screw change did not provide results I normally get. Barrel pivot and lockup were tight with no slop. Sorry, no photos.
I received the package deal plus free pellets-pen-case, free shipping, and a discount. That makes this rifle worth around $70. IMO a fair price for a better quality B19 clone with a nice wood stock. At this price point I don't care about warranty service. Time to go in for a closer look.
Yes, VERY DRY inside. Overall I do have to note that this is one of the nicest looking and best made B19 style springers I have, except for one part. More on that shortly.
I deburred a few sharp edges but most were already broken. Never seen that in a B19 before. Cleaned up what little factory lube there was. Applied a Moly paste skim coat in compression tube and on piston bearing surfaces. I used a small acid brush to paint the spring and guide with a layer of my favorite tacky/stringy marine grease. Reassembled the power plant and turned my attention to the trigger.
Pretty standard B19 trigger except for one addition. I'm assuming someone at Diana thought the "Crosman Trigger Bearing Fix" was the cheapest/best way to make this trigger group better. So they added a washer about the size of the popular bearing fix. My problem with this two-fold. First, the part they added was a badly punched and malformed fat steel washer with a very rough surface finish. Second, was that I've NEVER had results that I liked with the bearing fix on any of my B19 style triggers. I removed the faux-bearing which returned the trigger to its normal B19 state.
I then carefully polished the sear edges, burnished in some Moly paste, and reassembled the trigger on the rifle. NOW the longer adjustment screw works. After a little fine tuning the trigger has a long-ish but light (faux) first stage. A good stop when the trigger blade contacts the sear lever, and a 2-3 pound short snap to fire. That is what I expect and WANT on my B19 triggers.
Shot cycle after the re-lube is a short and sweet "thump" with no more spring twang. Actually pretty darn good for this simple power plant. Trigger is right where I like it. Shooting this rifle is now fun and accuracy is sub-dime 10 shot groups at 30' with just the open sights.
I'm not going to add the recoil mount and scope for awhile. With the current shot cycle it feels like the special scope mount is not really necessary, however I will use it when I'm ready to mount the included AO scope.

If you look at this link, it clearly shows it's using the B25 platform.

Maybe I'm confused?
The rifle I have in my hands right now is the Diana 250 purchased directly from Pyramyd Air. The Diana 250 Box was factory tape "sealed". I have stripped this rifle down to individual parts and completely rebuilt it. I can assure you it has the side latching piston and a trigger that is almost identical to MANY of my older Crosman break barrels based on the B19 platform. The position of the safety may look like other Diana rifles, but the internal trigger parts are the same as the old Crosman trigger.
Experts feel free to correct me, but I thought the B25 platform had the T-05 clone trigger and center-post latching piston. Basically this rifle here
http://flyingdragonairrifles.org/PDFs/XS25diagram.pdf (http://flyingdragonairrifles.org/PDFs/XS25diagram.pdf)
the Xisco XS25, which is nearly identical to my Blackhawk. I thought the Blackhawk and XS25 air rifles were considered the B25 platform. Am I wrong?

I also love a good B19. Favorte is the Stoeger X10.
I just can't get over the ugly thimbhole design of the Diana 250.
Maybe if I could get one in a Crosman Optimus stock, lol.
-
It does seem that Dian don't know what they are selling either. The website shows the 250 built on the B19. The catalogue shows it built on the B25.

I agree it's not the most visually attractive implementation of a thumbhole stock out there, but the actual woodwork and grain on my (stained Beach?) stock looks pretty nice for a $70 rifle. Also, it "feels" really comfortable to shoot. The dimensions are just the right size (for me). That means a lot of people larger and smaller than me may not like this rifle, period!
I expected this rifle to be a B19 in a different dress. Was hoping that a tiny bit of Diana's legendary quality would upscale this B19 a little. I think I can see a little of her magic in this rifle. Maybe not the best one, but IMO it is one of the nicer (after the tune-up, of course) B19s I own. I have no regrets buying this rifle in the special package deal offered at the time. I DON'T think the rifle by itself is worth $129.99. It's not THAT good.

I think you guys may find that the Diana Two Fifty and the Diana 250 are 2 different guns.

I agree.
I believe the CORRECT name for the rifle being discussed here is the "Diana Two-Fifty"
https://www.diana-airguns.de/en/products/break-barrel/detail/diana-two-fifty (https://www.diana-airguns.de/en/products/break-barrel/detail/diana-two-fifty)
The confusion stems from the fact that both PA and AGD listed and sold the Diana Two-Fifty bundle as a "Diana 250" bundle. Pretty much EVERYONE ELSE I could find is currently listing and selling the Two-Fifty as a 250.
I'm assuming the Diana 250 was an older version rifle which was maybe a parent of B25 clones?
Center post piston latch and some version of TOx trigger with the single trigger blade and thumb-safety.
I did a quick internet search for this older 250 version but only the newer version Two-Fifty shows up with any search I attempt.
It would be appreciated if someone could post a link to any information regarding the older version rifle that used to be called the "250".
The "Two-Fifty" IS a B19 clone with some parts being a little better quality than the average B19. Some parts lower quality IMO.
This is a side piston latch with simple B19-like (older Crosman-Gamo-etc.) trigger group.
Some folks SEE the single trigger blade and thumb-safety that LOOKS EXACTLY LIKE one of the TO triggers and assume this rifle is in the B25 family. DON'T be fooled! This is a B19 trigger group with a special thumb-safety. I think Diana did this on purpose so that the Two-Fifty LOOKS like it might have a T0x style trigger.
Regarding the Two-Fifty barrel pivot... I don't have any photos of mine but I'm pretty certain it is the same old B19 pivot assembly (see parts view). I didn't see any special redesign here so folks that have an aversion to that old pivot design should avoid this rifle as well.
-
Yup... I believe the 250 is genuine Diana.. The Two Fifty is Chinese.
However, I recently bought a .177 Two Fifty which I'm still breaking in and it's coming around nicely. Just a bear for this old guy to cock at this point.

According to Hector, the pivot joint WAS modified and improved on the Two-Fifty over the B19:
"the barrel block to forks attachment was revised and two hollow pins with scalloped ends now make the attachment much more solid than in the original B-19."

That is good news!
Hopefully the implementation of that redesign is better quality than that new trigger bushing. The trigger bushing i removed (discarded) from my Two-Fifty looked like it was formed from birdpoop by 5 year old child. Very nice B19 clone overall.

The Diana 250 was the model below the 35 and has about the same power as the HW30. It's depressing, as a Diana aficionado, to see that the Diana Two-Fifty is based on the B19 which was, in turn, a copy of the Gamo 220/440/890/S1000. 😪

Any pics of the pivot and trigger mech available?
-
Diana 250, RWS 34, XS25, Ruger Air Hawk, BH and BHE are basically the same gun. Same trigger assembly and safety. Good guns.
The B19 trigger and safety are totally different.
B19 barrel lockup is two apposing wedges. XS25 has a ball detent and apposing wedge. Both use a threaded pivot bolt. 25 has a nut.
B19, Crosman Optima, Storm, Quest, Phantom, Fury and G1 Extreme all the same gun. Good guns. Great guns with a GRT trigger or RC roller bearing mod.

Old people like me aren't to good with pics but Google and U-tube are your friend.
