AirArms ProSport UnderLever

The Air Arms ProSport is widely considered one of the finest spring-powered air rifles ever made. Combining precision engineering with elegant design, it offers the feel of a professionally tuned rifle straight out of the box. Available in .177 and .22, the ProSport delivers exceptional accuracy, smooth firing behaviour, and outstanding build quality.

One of its defining features is the fully integrated underlever cocking system. Unlike most underlever rifles, the ProSport’s lever is discreetly built into the stock, giving the rifle the clean, classic appearance of a break‑barrel while maintaining the power and consistency of an underlever mechanism.

If you're searching for a top‑tier spring rifle, the ProSport is a proven favourite among hunters, target shooters, and enthusiasts who demand the very best.
