Alfa Precision makes high-quality barrels designed with the Leshiy 2 in mind. Given that the Leshiy 2 shoots straight from the magazine, this is no minor point. 

Alfa Barrels are available in calibers .177, .22, .25 and .30 in any barrel length. They lack choke, making them a good option for those shooters who are more slug oriented, and with their polygonal grooves they can also handle pellets very well.
