Diana Chaser CO2 Air Rifle Kit
The Diana Chaser Rifle Kit is a pistol and rifle in one! This lightweight CO2 airgun was designed for hours of fun outdoor target shooting or as an ideal indoor plinker. Fueled by a single 12-gram CO2 cartridge, the Chaser is a finely balanced modular platform that lets you choose whether a pistol or rifle is a better fit for your trigger time.
Available in .177 or .22 Diana had shooters of all ages in mind with the airgun's feather-light weight of 3.1lbs. But do not let its slight build fool you! The Chaser is a capable plinker and target puncher that can send its rounds downrange at speeds up to 642 fps in .177 and 500 fps in .22 caliber. To get started shooting, first decide if you want to use the Chaser pistol or transform it into a modular air rifle. To turn the pistol into a rifle, loosen the three set screws that secure the barrel and pull the barrel from the breech. Insert the moderated 17.7” rifle barrel into the breech and tighten the set screws. Remove the pistol grip cap by unthreading the securing screw on the underside of the grip and sliding the cap off of the grip. Then insert the butt stock into the holes on the grip and replace the securing screw. Once those parts are in place, you’re ready to load up and sling lead. As a bonus, the elongated barrel has the added benefit of increasing pellet speed by 35-40 fps over that of the pistol.
To get started, load a single CO2 cartridge, cock the smooth bolt-action, load your pellet, and pull the trigger. While the Chaser only needs a single CO2 cartridge, a compartment on the bottom of the grip opens up a storage area to hold a second CO2 cartridge to keep more air power on deck. Each includes a front blade sight with an adjustable rear sight and an 11mm Dovetail to zero in on targets with a scope.
Diana includes a single shot tray for precision shooting, but the Chaser can accept magazines used by its big brother the Stormrider. With the addition of indexing magazines, transform your single-shot Chaser into a multi-shot repeater pistol! These indexing mags hold 9 shots in .177 and 7 in .22 and cut down your reload times significantly. The magazines are sold separately but are readily available here at Pyramyd Air.
If you want a lightweight pistol/rifle combination built for dropping cans and peppering paper targets, choose the Chaser Rifle Set and see what your shooting sessions have been missing.

Light weight, pistol/carbine/rifle all suppressible. Able to use as single shot with shot tray or as a repeater with accessory mags. I built a quiet pellet trap and can use in a 3 car garage at 3 meters.
Things I would have changed:A little more power perhaps. A better manual with exploded parts diagram.
What others should know:There are good vids on Utube. Make a CrownSave type cleaning kit with 80-100 lb. leader. (Also vids available) Be careful not to use a solvent that damage your seals. I ordered a long pic rail off eBay so I can mount a 2 moa green dot forward of the receiver.

Light,Accurate,Quiet. It is so quiet that it does not seem powerful but then I took the silencer off the long barrel and she really barks. Mine was putting pellets in the same holes, I could not believe it.Ran it through the Chrono and its right at 500 FPS, put a lighter spring in the air chamber and lightly stretched the hammer spring and got 525 with poly mags and 545 with RWS Hobby
Things I would have changed:Would be nice to have some bolt on extensions for the stock, a little short for an adult but manageable. The bolt seems a little small and weak, hopefully it holds up.
What others should know:For the price you cannot beat it, buy one and have some fun!

How to order
Have not been able to secure a sound seal with the CO2 when I installed the long barrel.
You need to take the small brownish 0-ring off the pistol barrel (breach end) and install it on the rifle barrel. There is a spare included in kit but I don't seem them for sale separately.
What are the measurements of the threads on the barrel?

The silencer! It makes this gun very quiet. You don't want your neighbors thinking you're shooting a firearm in your backyard and for the unfamiliar, it is hard to differentiate between the "pop" of an airgun or a low-caliber (like .22lr) "pop." This helps avoid problems, and of course, doesn't disturb anyone. The rifle is very accurate out of the box. The quality seems very good (although this is made in China, not Germany, for Diana.) Watch the video on how to change the pistol into the rifle. There are a couple of good "tips" to know before you do. You will have to disassemble the rifle (or pistol) on occasion anyway when a pellet gets stuck in the barrel from a near-dead CO2 cartridge, so you might as well get familiar with the correct procedure right from the beginning. This is light weight rifle with very little kick - and a very cool looking "sniper-style" rifle,
Things I would have changed:- Perhaps a bit longer butt stock... - But DEFINITELY change the position of the trigger lock. I see why they put it there (it's basically just a slide bolt across the trigger) but it is hard to find by just feeling around and your finger doesn't go naturally to that position and it is ON the trigger, which means you have to fiddle with the trigger! That's the antithesis of "gun safety" rule #1: "Keep your finger off the trigger until you're ready to pull!" What were they thinking? Yes, while it's a cheap and simple (and effective) mechanism, it isn't a GOOD mechanism because it shouldn't be on the trigger! For anyone who is trained on a firearm, this is a big "no-no." Move the #%&@# safety either to another place NOT on the trigger and easy to find without looking, or go to a lever-style mechanism typically found on firearms!
What others should know:- Consider getting an inexpensive "red dot" sight. ($25 on Amazon for a cheap one.) It makes shooting a lot more fun - and accurate. For $25 it'll show you what it can do and if it lasts, great, if not, you can invest in a better quality one if you like how it works for you. - The Stormrider magazine is a very good addition for shooting varmints and pests, as you'll need the capability of multiple rounds in quick succession; otherwise, the single-load is fine for target practice. If you get the magazine, you'll have to invest time in finding then watching useful videos on how to load it and how to insert it as it isn't obvious and no information comes with the product or is on the website.
