Vanquish suppressor overview
Experience innovation and precision at its finest with the Vanquish AR9 integrally suppressed barrel. This groundbreaking suppressor breaks free from the constraints of traditional silencers, thanks to our patented zero baffle design.
Gone are the days of needing to shoot expensive, heavy-grain subsonic ammo just to sound good. Thanks to a ported barrel design, the sonic crack of 115-grain ammo is eliminated, resulting in a shot that sounds just as good as heavy-grain subs.
Already shooting subsonic ammunition? Our adjustable, ported barrel ensures you’ll achieve the perfect shot every time. Preserve the velocity of the round by closing up to 8 ports.
Maintenance is a breeze with the Vanquish. With no internal baffles to worry about, you can focus more on your shooting and less on post-range cleaning.

Vanquish Helpful Resources
If you have questions regarding the Vanquish, please see our Vanquish resources page. It contains detailed videos and answers to many of the commonly asked questions we receive.
Handguard compatibility:
The integrally suppressed barrel can be used with any mil-spec upper receiver. The suppressor’s shroud has an outer diameter of 1.5″ and requires a handguard with a minimum inner diameter that accounts for this dimension.
M-LOK attachment compatibility:
Depending on the handguard you choose, you may need to use shorter M-LOK screws when installing attachments. This will prevent the screws from coming into contact with the suppressor shroud. It’s worth noting that most screws provided with attachments are longer than necessary. Based on our experience, we have found that the Vanquish barrel and handguards with a minimum inside diameter of 1.72″ are generally compatible with most M-LOK accessories. Just remember to use shorter M-LOK screws for optimal fit.
Barrel installation:
Vanquish Barrel installation video
Installing the Vanquish suppressed barrel is the same as a standard barrel. Start by aligning the index pin on the barrel extension with the slot in your upper receiver. Then, follow the instructions provided by the handguard manufacturer to install the barrel nut and handguard. Lastly, slide the shroud over the barrel and securely attach the end cap to the threaded section. For detailed assembly instructions, refer to the instruction manual provided.

Doesn’t suppress as well as a suppressor with baffles. Even subsonics with all barrel ports open are audibly louder than what my AR9 shot before with a SilencerCo Hybrid 46 on it. The ability to shoot supersonics and have them slow down to subsonic speed due to the ports is a nice feature for sure and saves money on subsonic ammo.
One thing that should be addressed is the length between the barrel and the start of the shroud. I had to buy a whole new handguard and barrel nut because the but was too long for the shroud. It was harder than anticipated to find one with a short enough nut to work with this which was an expense I wasn’t anticipating or wanting since I liked the handguard that came with my AR9 from Palmetto. I foresee a lot of folks wanting to put this on a palmetto platform and will all be disappointed when they try to install it and have to spend $150-200 more than expected for a new handguard.

Hey Landon,
Thanks for leaving a reply! As you point out, your comparison suppressor (SiCo Hybrid 46M) will definitely be quieter. Being a .46 caliber can, it has a ton of volume and lots of baffles. Our target suppression was in the range of other 9mm suppressors. Here’s a link to our published testing results: https://angstadtarms.com/vanquish/#results. Thank you for also pointing out the PSA handguard barrel nut is not compatible. When we designed the Vanquish AR9 we purchased just about every handguard and we thought we had accounted for extra long barrel nuts, but it seems the PSA is even over the longest barrel nut we encountered.
