In the Sporter section of Paulina's links they are .22's (rifles and pistols).
Ah, right, there's a sporting section, I missed that:
LONG GUN SPORT department includes weaponson which you must have a permit. We present you here long, high-performance arms and recreational rimfire ammunition in caliber .22 LR (5,6mm). The high-performance weapon is represented by Walther brand - German manufacturer with a 125 years of experience and a Swiss producer Hammerli sporting weapons. Under the brand name COLT are also produced in Germany rimfire rifles facilities which are replicas of the legendary US Army combat weapons such as rifles M4, M16 and Colt pistols, 1911. The purchase of this weapon is only possible in the showroom with a valid promise to buy weapons and proof of identity .
Yes, this is a real sporting gun (you can even tell by the price lol). But the site says one has to show a valid permit for sporting guns and ID to buy it (you can't buy it online).
