Description

The Air Arms Precision Biathlon rifle delivers world-class accuracy. Air Arms is known for making extremely accurate guns, and the Biathlon is no exception. This air rifle is dressed in a unique white poplar stock with adjustable black cheekpiece and rubber buttpad. If you don't shoot competitively and just want a very accurate repeater, install a compact scope on the 11mm dovetail. Because the dovetail is very short, you'll need to use a 2-piece mount.

Keep your extra rotary clips in the slots of the right-hand forearm. Load them before each match so there's no fumbling when the pressure is on!

Accurate and fun to shoot.

Expensive. For the money should have included Butt Spacers and Front Aperture Inserts. Would have also been nice if a prone position sling was offered.

For target practice order the 10 pellet clip and you will not have to reload as often.

What a great rifle. The accuracy is incredible. The weight and adjustable features are terrific. A truly great air rifle

I am not convinced on the number of shots per fill, I find that I am between two and three hundred before I need to refill. Other than that a great piece of gear.

There are so many things about this gun to like it is hard to start. The balance and the feel of this gun is unreal and the adjustments to make it fit your body, enhance the experience. The trigger is as smooth as silk and pulls the pellet right to the target. It seems like it shoots forever on a single charge. It is very nice to have 20 rounds to shoot off without having to reach into a pellet container. It is quite and doesn't let your neighbors know what you are up to in your backyard. The gun instills confidence in you and when you miss you know that it is your technique to blame and not the gun. After a quick sight in, I was doing dime size clusters of 20 rounds quicker than you could say Air Arms, because of the 4 magazines. When you look at it there is no question that this is a quality rifle.

You will need a few adapters to be able to use a hand pump with this gun. It seems to take longer to pump up by hand then my other PCPs. My son is left handed and doesn't seem bothered by the right handed stock when he shoots it.
