It’s finally here. After much sweat, some of my own blood, and other people’s tears I’m proud to introduce to you the Diana Stormrider Tactical Conversion Kit. This kit includes an AR grip adapter, MILSPEC AR buttstock and adapter, and a tactical tri-rail, M-Lok handguard, and traditional forearm. It is highly functional, looks slick, made in America, and is still very affordable. And wait, there’s more… If you get all three a 10% discount will be automatically applied in your cart.
I’ve just added a side folder option as well. The side folder is not compatible with the standard adjustable stock tube. You will need the Rear Pic Adapter in order to mount a picatinny clamping side folder to these airguns. It’ll only work with our AR grip adapter. The Rear Pic has a 1/4″ cap screw that secures it to the grip adapter via an inset nut.
This kit is compatible with the Gen I and Gen II, but please pay close attention on the forearm/tri-rail. If you have a downward facing gauge instead of the forward facing gauge on the end of the air tube you can only use the traditional forearm with gauge hole and M-Lok handguard w/Gauge Hole. If you have the forward facing gauge you have the option to choose between traditional forearm, tri-rail, or M-Lok Handguard No Gauge Hole. The tri-rail and M-Lok handguard are not compatible with the stock barrel band/rear sight post. They replaces the barrel band and move it further forward. This means no open sights. If you choose the traditional forearm you can still use the rear sight post/barrel band and pair it with our Diana Chaser barrel band to add accessory rails and a forward barrel band.
These should work on the Diana Trailscout, Artemis CR600W, PR900, PR900W, SMK PW900 as well. I haven’t tested them all. If you have any issues with fitment just let us know and we’ll take care of you. This kit is also compatible with the Stoeger XM1 PCP Rifle (not the bullpup). For the XM1 you will need to select the traditional forearm without the gauge hole and you will need an M5X25 Button Head Screw to attach it to the OEM barrel band.
The AR grip adapter comes with a Made in USA matte fiber reinforced MILSPEC A2 grip from Outerwild Outpost pre-installed. It is compatible with AR grips without beavertails. It installs using the stock metal trigger guard and hardware.
The adjustable stock gives you an adjustable LOP stock with QD compatibility for slings, etc. The stock tube is compatible with MILSPEC adjustable buttstocks. It is reinforced with a steel bolt.

My preferred handguard is the M-Lok version. I’ve added an option that is compatible with the downward facing gauge. The M-Lok Handguard looks goofy with the Manometer (Pressure Gauge) in its stock configuration, but there’s a simple fix…
If you don’t want your pressure gauge hanging out in the breeze you can easily shorten it by removing the extended bushing and reinstalling the gauge.
You’ll need a 19mm and 14mm open box wrench or an adjustable wrench.
Degas your airgun! You can do this by simply dry firing it in a safe direction repeatedly until it is no longer pressurized.
Remove the OEM stock.
Use the 19mm wrench or adjustable wrench to remove the pressure gauge. Turn counter-clockwise.
The gauge and bushing may come off together. If they do, use the 14mm and 19mm wrench to remove the bushing from the gauge.
If the gauge came off without the bushing set it aside and remove the stem with the 14mm wrench or adjustable wrench.
Now reinstall the gauge only, without the bushing. You can install it with or without the O-Ring that was in the bushing.
Now continue the installation of the handguard. It will look like this:
