Questions & Answers
How will this fair on a 9mm Vector? Expert Answer

The SLR Synergy 5.56 Muzzle Brake will NOT work on a 9mm pcc/rifle etc. This brake only works with calibers with a bullet diameter of .224" or less. 9mm has a bullet diameter of .355" and will cause damage to the firearm and the shooter.

It will so long as the Galil Ace has a 1/2x28 thread pitch.

Product Info for SLR Synergy 5.56 Muzzle Brake/Compensator/Flash Hider, 1/2x28 Thread

With an SLR Synergy Muzzle Brake/Compensator/Flash Hider, 1/2x28 Thread, you get the best of three worlds in one device.

This SLR Synergy Multipurpose Muzzle Brake/Compensator/Flash Hider, 1/2x28 Thread reduces recoil and muzzle rise by reducing gasses expelled by the muzzle brake, compensator, or flash hider, respectively. Get the SLR Synergy One-Way Muzzle Brake/Compensator/Flash Hider, 1/2x28 Thread for your AR, AK, or shotgun to reduce recoil, flash, and muzzle flash.image
