Garland, yes Sir it can. The Rossi RS22 comes with a 10-round steel magazine, but can also use the 25-round Model 702 .

Garland - This, from a review of the Rossi: This rifle is very similar to the recently-reviewed Mossberg 702 Plinkster. Both rifles are built by the same manufacturer in Brazil, and both a are very affordable. The sights are the same set of excellent adjustable fiber-optic sights, and the magazines will interchange, so this Rossi will work perfectly with the Mossberg twenty-five round magazine that they sell for the 702 Plinkster.

Garland, Yes a Mossberg 702 magazine should be perfectly compatible with an RS22
