The Weihrauch HW90 is a gas piston-powered gun. A gas-powered gun works the same as a spring-powered; however; in this case, the coiled spring in the chamber is replaced with a gas strut. The air in the strut is already compressed and when the gun is cocked, more pressure is applied to it. The pressurized air is kept under tension until the trigger is pulled. When the gun is fired, the pellet is propelled downrange in the barrel due to the propellant force from the compressed air. A gas piston rifle has no spring fatigue or spring torque, even if left cocked for hours. It provides you with smoother cocking and smoother shooting with less recoil. It also functions perfectly in low temperature than in the case of the spring that can get affected by harsh weather conditions and lasts longer than the metal spring. Weihrauch HW90 air rifle has a caliber (the internal diameter of the bore) of .177(4.5 millimeters), .22(5.5 millimeters) and .25(6.35 millimeter). Weihrauch HW90 is a break barrel gun, to cock it, you need to pull the barrel downwards while holding the gun upwards; insert the pellet and swing it back to its natural position. The first few times may seem difficult but after a couple, you’ll be able to work it perfectly. Break barrel guns give you unlimited shooting capacity. You can shoot thousands of rounds without worrying about running out of gun powder. Also, the Weihrauch HW90 is a single shotgun, this means you can only shoot one pellet at a time, after which you’ll have to manually cock it and insert another pellet. Single-shot action gives you control over what type of pellet you want to shoot, and how you want to shoot it. It also improves your shooting skills because you’ll always want your first shot to count.
Since it has 3 types of calibers, Weihrauch HW90 has 3 types of ammo for each caliber: 177 calls uses .177 pellets, .22 call uses .22 pellets, .25 call uses .25 pellets. .177 pellets are lightweight, popular and very cheap; this makes them cost-effective and suitable for plinking, and target shooting. .22 pellets are heavier than .177 pellets, they produce more downrange knockdown power and have a more stable trajectory (its path towards its target); this makes them suitable for field hunting and pest control. The .25 pellets are heavier than .22 but produce less velocity than .22, if you’re hunting small game, the .25 will surely take down critters with a single shot, there isn’t much difference with the .22. However; if you’re larger critters like raccoons, there is a substantial difference in placement and range because .22 requires precise headshot while .25 can do the job with a chest shot.
The stock on the Weihrauch HW90 is a pure beauty, being of a varnished and plain beech. It has a well-rounded shape and includes substantial pistol grip with pressed checkering panels. The butt has a nice subtle rubber recoil pad and the stock is comfortable on aim.
The Beech stock gives it lots of advantages; first, it has high hardness, has high resistance to abrasion and has high hardness. Secondly, it has a beautiful wooden texture. The beech stock has a very nice finish; it also has a very nice uniform and gorgeous texture.
The substantial pistol grip allows you better leverage on the gun. The raised cheek piece allows your eye to align with the scope while keeping your cheek firmly resting on a solid surface of the firearm for maximum stability. The stock is ambidextrous, meaning both left-handed and right-handed folks can use it comfortably.
The sight on the Weihrauch HW90 is a globe front sight and a fully adjustable rear sight. The front globe sight consists of a hollow cylinder with a threaded cap; this allows you to interchange the front sight elements. The most accurate iron sight shooters like Olympic and international competitions (50m, 3-position) use globe sights where the front sight is not a post but an aperture. The rear sights are fully adjustable for wind age (allows you to adjust left and right) and for elevation (allows you to adjust up and down)
Scope Mount: the scope mount on the Weihrauch HW90 is an 11mm dovetail. The dovetail is a set of parallel grooves that run along the top of the receiver on which you clamp the base of your scope. The dovetail is lightweight so it doesn’t add weight to your rifle it also ensures your scope is nice and tight to the bore of your rifle.

The Weihrauch HW90comes with an elite two-stage adjustable trigger. This amazing trigger allows you to adjust the weight of the pull and the weight of the travel.

The Weihrauch HW90 hardly requires lots of care; however, you can take these precautions to make sure your air gun remains as good as new:
- Maintain your bluing: the outer metalwork of your air gun has a finish known as the bluing, make sure to always keep your rifle dry as this can rust not just by contact with water but even damp atmosphere. Clean the dry surfaces with an oily rag you can use WD40 or 3-in-1.
- Get a rifle rest: Buy or make a combined toolbox and rifle stand to make working on your gun easier. By having your support, both of your hands are free to work well with, this makes it easier to work and prevents possibility your rifle falling due to fatigue.
- Preserve your gun: keep your guns away safely, you can get a gun cabinet for that, however always make sure your cabinet and gun are dry to avoid rust and condensation before storing them.
- Love your stock: your gunstock is probably the best bit of your air gun. Oil finished stocks should be oiled regularly to keep their appearance. The wood needs to be dry and the stock oil should be applied by hand; the heat from your hand warms the oil helping it to penetrate the grain. Lacquered stock can be protected using furniture wax or beeswax.
- Also, remember to oil your gun every 250 shots and to clean the barrel with cleaning rod every 500 shots.
