The Volquartsen Vanquish 22 Summit ISR is an integrally suppressed .22 LR rifle with a straight-pull bolt, made by Volquartsen in collaboration with Angstadt Arms (part no. AAVV22BMFR). This version ships in an FDE Magpul stock. Volquartsen describes the 18.5-inch ported barrel as reducing .22 LR to subsonic speeds, while the straight-pull action keeps mechanical noise to a minimum. The suppressor body is machined from 6061 aluminum with a Cerakote finish, and the receiver is CNC-machined with a top Picatinny rail. A TGS trigger group breaking at 1.75 pounds and a Bentz match chamber round out a rifle aimed at quiet, precise rimfire work.

Which magazines fit the Summit ISR? It accepts Ruger 10/22 magazines, and Volquartsen includes one factory Ruger 10/22 10-round magazine.
