The Rugged Suppressors Oculus22 is a modular rimfire suppressor built entirely from 17-4PH stainless steel, finished here in black Cerakote with a 1/2×28 direct thread mount (Rugged Suppressors part no. OCU22). The ADAPT module lets you run it at 5.25 inches or at 3.25 inches. Rugged rates it Belt Fed Rated for .22 LR and full-auto rated for .22 WMR, .17 HMR, .17 WSM and 5.7x28mm. An all-stainless body means you can clean every part with nearly any method. It suits a threaded rimfire rifle or pistol used for training, plinking or small-game hunting.

Key Specifications

• The primary rating is .22 LR Belt Fed Rated, supporting sustained rimfire fire.
• It is also full-auto rated for .22 WMR, .17 HMR, .17 WSM and 5.7x28mm, so it covers a range of rimfire cartridges.
• Standard configuration length is 5.25 inches, for the most suppression.
• Short configuration length is 3.25 inches, which suits short rimfire barrels.
• Standard configuration weight is 6.9 ounces, moderate for an all-stainless suppressor.
