Not designed for the faint-hearted, the Diana RWS 48 air rifle impresses with beautifully crafted German engineering, this gun stands out both in performance and presence. It fulfills its purpose as a potent, full-size sporting air gun suitable for small game hunting, pest control and plinking.
Table of Contents
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 propellant
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 a side lever gun, in order to cock it, you need to pull the lever downwards while holding the gun upwards, 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 as you want without worrying about running out of gun powder like other rifles.
The stock is made of beautiful beech wood. Beech stock gives a lot of advantages: First, it has high 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 also soft and smooth so you can feel the good visual effect.
The Diana RWS 48 has an ambidextrous stock, so whether you are a lefty or a right, you have no problem shooting it.
The Diana 48 has a very cool sight. The front sight rides on a dovetail and held down with a dove screw. The dovetail allows you to aim directly at your target, it’s sleek and nice to look at. The rear sight has standard RWS all metal and it has a spring loaded ball bearing that helps it to stay where you put it. 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 improve accuracy.
Diana RWS 48 Trigger
The RWS Diana 48 comes with T05 two-stage adjustable trigger. T05 is made of plastic (weapons-grade plastic) so don’t worry about the trigger possibly snapping on your fingers during cold weather.
With the trigger pull of 2lbs 13oz. 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. But it’s hard to improve on perfection and I don’t see where any changes would be necessary.
Velocity, Accuracy and Power
Velocity: the maximum velocity of the RWS Diana 48 is 1100FPS (feet’s per second) in .177cal and 900FPS in .22cal. These are high-end velocities compared to other air rifles on the market.

The velocity of the RWS Diana 48 differs by the calibre size but is consistent between pellet grain size which is pretty impressive. So be sure to choose the calibre and pellet size that best fits your usage.
Accuracy: The RWS Diana 48 has a great reputation on accuracy. Shooting from rest, at 25 metres, five JSB Exact pellets in a group measured .875 inch edge to edge (just under .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 .22 cal model 48 when shooting 14.3 grain Crosman Premiers.
Noise: The RWS Diana 48 is very quiet, I have seen lots of customer reviews without a single complain about the noise. So it’s suitable for indoor target practice without disturbing the neighbours or takes it 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 without it feeling awkward.
- Automatic Safety: another exciting feature about the RWS 48 is the automatic safety. The automatic safety assures you only shoot when intended to, thereby protecting you from injuries that occur from accidental discharge of the pellets. The automatic safety engages immediately the side lever is cocked back in place after inserting the pellet.
- Lever Cocking: the side lever cocking allows shooting more accurately 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, it is heavily packed and has high resistance to abrasion. So you don’t have to worry about the stock wearing out for as long as you have it.
Standard RWS Rear Sight with spring loaded bearing: the spring-loaded ball bearing on the RWS Diana 48 holds the setting of your site ensuring it stays where you put it, so no need to worry about losing your previous after using it. 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.
