About
What it is, and why it matters
The Mendoza RM-22 is a Mexican semi-automatic sporting rifle chambered in .22 Long Rifle, manufactured by Productos Mendoza S.A. It operates on a simple blowback action and feeds from a 17-round tubular magazine. The rifle features a German beech wood stock, a rubber forend, an anodized finish, and a manual safety, and is sold as an affordable plinking and small-game rifle across several trim levels (RM22-1000, -3000 and -6000).
Productos Mendoza, founded in 1911, is best known for Rafael Mendoza's light machine guns for the Mexican Army, but today the family firm mostly builds affordable .22 rimfire sporting rifles like the RM-22 for civilian shooters.
Marketed as an entry-level .22 LR rifle. Manufacturer lists roughly 1.4 in groups at ~50 m and a trigger pull of about 2.55 lb. Empty weight is not published by the manufacturer.
