Description
There's something great about a .22 that sounds more like a stapler than a rifle, and that's exactly what the Angstadt Arms Vanquish AR-22 delivers. Instead of hanging a can off the muzzle, Angstadt built the suppression right into this 12-inch barrel assembly. A series of precision-tuned ports bleeds off gas as the bullet travels down the bore, pulling standard velocity .22 LR down to subsonic speeds before it ever leaves the muzzle. Translation: you can feed it the cheap bulk stuff and still get that hushed, backyard-friendly report without paying a premium for subsonic loads.
What Makes the Vanquish AR-22 Different
The big story here is the patented baffle-free design. Traditional rimfire cans are notorious for trapping lead and carbon in the baffle stack, which means tedious cleaning sessions and the ever-present risk of a baffle strike. The Vanquish sidesteps all of that. When it's time for maintenance, the front cap comes off by hand, you slide the shroud off, wipe things down, and run a bore patch like you would on any rifle. No special tools, no soaking baffles in solvent for a weekend.
Built for Serious Rimfire Fun
Underneath the 6061 aluminum shroud sits a 416R stainless steel ported barrel with a Sporter chamber, all wrapped in a black Cerakote finish. The 0.920-inch bull contour keeps things rigid for consistent accuracy, and the whole assembly weighs a trim 15.2 ounces. It's even full-auto rated, so it can take a beating.
Dropping the Vanquish 22 Into Your Build
This 12-inch version installs like a standard AR barrel and is made for CMMG dedicated .22 LR bolt platforms, making it a natural fit for a Banshee-style rimfire build or a dedicated .22 upper. It pairs nicely with a 10.5-inch or shorter handguard for a compact, well-balanced setup. Because the suppression lives inside the barrel instead of hanging off the front, the rifle keeps its natural balance and handles the way it should.

Frequently Asked Questions
Do I need subsonic ammo with the Vanquish AR-22?
Nope, and that's the whole point. The precision porting bleeds off enough gas to bring standard velocity .22 LR down to subsonic speeds before the bullet leaves the muzzle. You get subsonic-level quiet while running everyday bulk-pack ammo. If you already have subsonic loads on hand, those will run fine too.
Will the Vanquish AR-22 work with my CMMG .22 conversion kit?
No, this barrel is built specifically for CMMG dedicated .22 LR bolt platforms, not the 5.56-to-.22 LR conversion kits. If you're running a dedicated rimfire bolt like the ones found in the CMMG Banshee .22 lineup or a compatible AR-22 build, it drops right in with no modifications. Double-check your bolt setup before ordering.
How hard is it to clean an integrally suppressed barrel like this?
It's one of the easiest suppressed setups you'll ever maintain. Since there are no baffles to trap lead and carbon, you just remove the front cap by hand, slide off the shroud, wipe everything down, tip out any loose carbon, and run a bore patch down the barrel. Standard .22 cleaning gear is all you need, and the ports don't require attention after every range trip.
Does the Vanquish 22 hurt accuracy compared to a regular barrel?
Quite the opposite in most cases. Because the suppression system is built into the barrel rather than hanging weight off the muzzle, the rifle keeps its natural balance and consistent barrel harmonics. The rigid 0.920-inch bull contour and 416R stainless construction are the same ingredients you'd find in a match-style rimfire barrel.
