Large Forward Blow Comp

614 forward blow comp alloy

The Large Forward Blow Comp is CNC-machined and 1.125" in diameter and 4" long.

The ports are machined at an angle that directs the noise blast downrange and away from the shooter.


  • Available with both a .920" and .875" diameter
  • 3oz base weight

Forward Blow Comp

671 22 45

Our Forward Blow Compensator helps with both muzzle rise and noise control by directing the noise towards the muzzle end of the firearm rather than back towards the shooter thanks to 16 precision machined ports that are angled in a forward direction.

Compensators are available in three outside diameters – .875", .920" and 1". Be sure and measure barrel diameter before ordering. As a reference, most 10/22 style barrels are .920", Ruger 22/45 Lite models feature a 1" diameter and the Ruger 22/45 threaded model uses a .875" diameter.


  • Threaded 1/2 × 28
  • Alloy compensators made from 6061 Aluminum and Type III Black Hard Anodized
  • 2oz base weight

32-Hole Comp

485 22 45 32 hole comp

The 32-Hole Compensator is CNC-machined from 416 stainless steel. It features 8 rows of 4 equally spaced holes that will not only minimize recoil but also disperse gases evenly for improved accuracy.


  • Available in .875", .925" and 1" diameters.
  • Threaded 1/2 × 28
  • 2oz base weight

Inferno Comp

244 inferno compensator

Add some flare to your rifle! The Volquartsen Inferno Compensator is now available as a separate item. CNC-machined from lightweight aluminum, this compensator is designed to not only reduce recoil but also help minimize flash.

Forward Blow Stabilization Module

143 front blow stabilization module black

Our Forward Blow Stabilization Module is designed to offer the best of both worlds – less recoil without the increase in noise.

Designed using the latest CAD technology available, the stabilization module features 16 forward angled ports. These ports are precisely optimized to align barrel gas to surround and stabilize the bullet for increased accuracy without increasing noise. And it is turned from lightweight aluminum so it will not change the balance or feel of your rifle.

Installs easily onto non-threaded .920" bull barrels with supplied socket head cap screw.


  • 2oz base weight

V-Comp for MKII and MKIII

194 ss v comp w sight

Large, single chamber compensator with six separate ports gives controlled release of muzzle gas for almost recoil-free rimfire shooting. Inner, rubber O-ring gives positive gas seal.

565 thread protector black
