The Angstadt Arms Vanquish 22 AR-22 barrel in the 12-inch short configuration is an integrally suppressed rimfire barrel for CMMG dedicated .22 LR bolt platforms (brand part no. AAVIS22A01). Its precision porting brings standard-velocity .22 LR down to subsonic speed, so the quiet comes without buying specialty ammunition. There are no internal baffles to trap lead or carbon, which means less cleaning and no baffle strikes. A 416R barrel sits inside a 6061 aluminum shroud with a black Cerakote finish, and the short version weighs just 15.2 ounces. It is a drop-in way to build a compact, quiet AR-22 rifle or pistol.

Key Specifications

• Caliber is .22 LR, the cheapest cartridge to feed a suppressed trainer.
• The chamber is a sporter chamber, which runs a broad range of .22 LR loads.
• The platform is the AR-22 with a CMMG dedicated .22 LR bolt, and it installs without modification.
• Length is the 12-inch short configuration, the compact option for a handy build.
• The barrel is 416R stainless steel, a common choice for accuracy and corrosion resistance.
• The shroud is 6061 aluminum, which keeps the suppressed assembly light.
• The finish is black Cerakote, a hard coating that matches a typical black upper.

• Angstadt Arms lists it as full-auto rated, a sign of how much heat the design is built to handle.
