Not designed for the faint-hearted, the Diana RWS 48 air rifle is an impressive gun. Built with beautifully crafted German engineering, this gun stands out both in performance and presence. It fulfills its purpose as a potent, full-sized sporting air gun suitable for small game hunting, pest control and plinking.

The Diana RWS 48 is a spring piston gun. As the name implies, it contains a coiled spring and a piston inside the chamber.
When the gun is cocked, the spring compresses until the hook at the rear of the piston engages inside the sear. When the trigger is pulled, the hook releases and this causes the spring to decompress.
The decompressed spring moves forward and applies pressure to the air inside. As a result, the force from the compressed air pushes the pellet out of the barrel.
A spring piston gun is simple to use, self-contained and has impressive accuracy. Diana RWS 48 is also a side lever gun. So in order to cock it, you need to pull the lever downwards while holding the gun upwards.
You then insert the pellet, push down the lock to release the lever and put it back up.
It may seem complicated at first but after a couple of times, you’ll be able to work it perfectly. This gun allows you to shoot as much since you won’t be worried about running out of gun powder like some of the other rifles.
The stock is made of a beautiful beech wood. Beech stock provides a lot of advantages. First, since beech has a higher hardness, it is heavily packed and has high resistance to abrasion.
Second, it has a beautiful wooden texture. When you observe the beech stock, you will see it has a nice uniform and gorgeous texture. The hue is beautifully textured for a smooth visual effect.
The Diana RWS 48 has an ambidextrous stock, so whether you are a lefty or a right, you will have no problem shooting it.
The Diana 48 has a very cool sight. The front sight rides are on a dovetail and are held down with a dove screw.
The dovetail is sleek and appealing, and it allows you to aim directly at your target. The rear sight has standard RWS all metal and it has a spring loaded ball bearing that helps it to stay put.
It also allows you to adjust for windage (allows you to adjust sight left and right) and for elevation (allows you to adjust the sight up and down).
If you like extra magnification then you’ll love that the Diana 48 comes with a standard RWS brand scope to provide extra magnification and improved accuracy.
Diana RWS 48 Trigger
The RWS Diana 48 comes with a T05 two-stage adjustable trigger. T05 is made of plastic (weapons-grade plastic) so don’t worry about the trigger snapping back on your fingers in cold weather.
With a trigger pull of two pounds 13 ounces, it’s probably the best trigger for an air rifle.
The T05 is adjustable so you can be sure to modify it to your liking, even though I don’t see where any changes would be necessary.
Velocity, Accuracy and Power

The velocity of the RWS Diana 48 differs by the calibre size but is consistent between pellet grain size, which is a very impressive quality. So be sure to choose the calibre and pellet size that best fits your usage.
Accuracy: The RWS Diana 48 has a great reputation with accuracy. Shooting from rest at 25 metres, five JSB Exact pellets as a group measured 0.875 inch edge to edge (just under 0.7 inch centre to centre).
That’s certainly good enough for defending the garden and hitting small hunting targets. Fun fact: the Bullseye Airgun club in Louisiana used to have a huge contingent of shooters who shot 48s and 54s in field target competitions.
Power: on testing, I registered a high of 22.73 foot-pounds of muzzle energy on a new 0.22 cal model 48 when shooting 14.3 grain Crosman Premiers.
Noise: The RWS Diana 48 is very quiet. Throughout all of the customer reviews, not a single user complained about the noise. This means that it won’t be too loud for indoor target practice and can be taken out to the hunting field for a nice stealthy hunt.
Features and Benefits
Here are some of the main features of the RWS 48 and their benefits:
- Ambidextrous stock
- Automatic safety
- Side lever cocking
- Two-stage adjustable trigger
- Beechwood stock
- Standard RWS rear sight with spring loaded ball bearing
- Single shot rifle
- Ambidextrous Stock: The ambidextrous stock is nice because it allows both lefties and righties to use it conveniently with no awkwardness.
- Automatic Safety: Another exciting feature about the RWS 48 is the automatic safety. The automatic safety assures that you only shoot when intended to, thereby protecting you accidental pellet discharge and potential injuries. The automatic safety engages immediately once a pellet is inserted and the side lever is cocked back into place.
- Lever Cocking: the side lever cocking allows shooting to be more accurate because it’s less sensitive to handling. It also accepts longer scopes for better magnification because the barrel doesn’t tip up and get in the way.
Two-Stage Adjustable Trigger: the adjustable trigger allows you to manipulate the amount of force it takes for the trigger to break and the shot to go off.
- Beechwood Stock: the beautifully finished beechwood stock on the RWS Diana 48 had high hardness, is heavily packed and has high resistance to abrasion. So you don’t have to worry about the stock wearing out.
Standard RWS Rear Sight with spring loaded bearing: the spring-loaded ball bearing on the RWS Diana 48 holds the setting of your site so it stays where you put it. There’s no need to worry about losing your previous sight. It also allows you to adjust for windage and elevation.
Single shot: the RWS Diana 48 is a single shot rifle, meaning it only allows you to shoot one pellet at a time. The single shot helps with accuracy because you’ll always want your first shot to count.
Shooting Range and Intended use
The effective shooting range of RWS Diana 48 is up to 50 yards. Some customer reviews said that it can take out squirrels with one shot from 40 yards. It is suitable for target shooting, small game hunting and pest control.
As of this date, the Diana 48 has a limited lifetime warranty.
