Are any of you folks aware of mods available for the Diana Chaser? When it was first introduced, there seemed to be a lot of speculation that it would be the next 2240 in terms of many mods/upgrades being developed. I did find an LDC with appropriate threads, but nothing else. I love my Chaser, and it is well designed for what it is.
For example, a power adjuster could take advantage of the barrel length and (possibly) allow altering the 50 shots/cartridge into a much more powerful 25 shots/cart.
Anybody know of anything?
so mods, like completely rebuilding the trigger assembly so you can adjust trigger travel to 1.5mm and all the slop is gone, with new pins, shims and a grub screw added to the sear for a trigger stop
or maybe using a Stormrider barrel cut down to 13 inches and using 12mm ID to 15 mm OD carbon fiber tubing so you can add the Air Venturi muzzle brake and globe sight and replacing the rear with a Williams sight
and resizing a 1/2-20 Marauder Pistol adapter so it will fit in that muzzle brake so you can add a LDC, filing the thread off
and adding a 4 inch Picatinny mount that bridges between the front of the breech using one of the front 2 threaded holes and a Stormrider barrel band and adding a 5 slot Picatinny mount on the bottom of the barrel band
so i guess the answer is yes but there is no store bought items, you have to gather this and that and try and fail and succeed and change before you are happy, if there is such a thing
about 100% of the stuff i used came off Ebay and of that stuff most came from China and you ask why, that's easy they had what i needed
i have 2 kits and a .177 pistol and another coming in tomorrow
now if someone would get off there dead A$$'s and get some parts for these pistols maybe we could do more customizing but i'm not holding my breath
i hope this gives you some ideas, send me a message if you have question, i'll try to help
will it ever become a 2240 type system to build off of no but with a good imagination you can make a custom pistol
all these mods were done with hand tools and a bench top drill press
take care

I would HIGHLY recommend the hammer de-bounce modification, available I believe from Airguns of Arizona. I have installed this mod in my .177 Plinkster, .177 and .22 Chasers. I've experienced roughly a 30-35% increase in gas mileage in all 3 guns, with no loss of power. Installation is pretty easy and straight-forward, but you may have to do some stock work, as the factory end plug is flush, but the replacement end plug is slightly domed. A little hand sanding is all it takes. Very easy, and well worth the effort.
Don’t mean to digress, but what is a “debouncer” mod and how does it work?
I have alot of Co2 guns and wouldn’t be adverse to improving gas economy...
I think any spring loaded device will do this: upon release, the spring does not just actuate and stop. It bounces a few to many times until settled. If I understand the issues with CO2 values, the bouncing releases more gas than intended in an ineffective manner, i.e., it wastes gas. A "debouncer" makes the spring actuate in one fluid movement and eliminates the bouncing, as the name implies, and the gas is used more efficiently. Maybe somebody else can explain it better. ?
There is now a left handed breach that you can buy. It will turn your bizarre rifle setup into a true right handed rifle.
If you think of modding in terms of making it better without having to buy stuff, i've done a few things to my chaser that could interrest you:
The swivel that's under the handle was always getting in the way (keep in mind that my chaser is in the rifle setup) so I just replaced it with a normal hallen screw.
Drilled some holes in the front handle to fit a "permanent" flashlight setup that leaves the small picatini available to install a bipod.
Messed with the trigger. I removed almost anything that was in there because the rifle was sometimes shooting by itself, the adjustment screw kept loosening. Now my trigger is reliable and very sensible.
Made a simple power mod by adding 4 washers between she spring and the hammer. It is about 3/16" thick (it is maxed out, if I put more the spring won't cock).
I also made the same power mod using the more powerfull spring from a crossman c11 pistol plus 10 washers but I uninstalled it because it made the cocking effort a little bit too stiff for my taste. But was working great and added a lot of power.
In canada we don't get the silencer so i fitted a plastic muzzle brake so it looks good.
if you use a Diana Stormrider barrel band and a M-lok 5 slot, screw and epoxy it in place, pointing backwards then no drilling needed but the 5 slot needs to have a flat bottom, some do some don't
and use something like this for your flashlight
i like the bottom grip screw idea, i will be stealing that
i do believe one of the best trigger mods is putting a stop screw in the sear and these triggers can be setup so light that you could fire my gun from your house
could you tell me where you found the bottom stock screw
Hey guys I don't mean to resurrect a thread that's 4 years old, but I saw Mr. Octopus' post above and had to ask something.
Does anyone know what type of screw he used for the bottom grip? I hate that floppy swivel that sticks out there on my Chaser and wanna replace it.
Like what thread pitch or diameter is the screw? Or even how long it is.
Any help would be greatly appreciated!
they hex 6mm x 1.0 x 20mm thread length binding screws i bought stainless but these could work but just buying one could be a problem
Dude you are the man! Thank you so much. I was sitting here thinking "nobody will reply to my post", so I was very pleasantly surprised when I read your answer.
So 6mm diameter is an M6 screw. I found a seller on eBay who sells M6x1 screws separately in whatever length, for a little over $4 each.

Say, you wouldn't happen to know what the dimensions of the screw next to the trigger guard are would you? The one that holds the frame to the co2 cylinder. I'd like to replace it with a stainless steel one (while I'm at it), purely for cosmetic reasons. Just to match the screw I'd be putting in the bottom of the grip.
Again thanks so much! Love the great white avatar. 😎
first off metric screws and nuts can be called in two ways
6mm or m6
when searching for screws and or hardware use both ways
i get most of my hardware out of China i wait 2-5 weeks but nothing that can't wait
the grip frame screw is a m5-5mm screw with 15-16mm of threads
a Screw Chek'r plate is a very handy way to check screws i use the ones i have all the time
Inch Screw Checker - Instant Identification of #1 - 5/16" Screw Threads (threadtoolsupply.com)
also, a stainless steel 6 inch ruler i use a General no.311me
General Metric/English Pocket Rule (311-ME) - Pocket Ruler - Amazon.com
they are tools that could last a life time, they are cheap and will make your life a lot easier
the button screw you picked will have a smaller head size than the binding screws that i am using
