Most .30 caliber rifles have a hefty muzzle blast, especially if you use large calibers like .338 Lapua Magnum and 30.06. The muzzle blast can make it challenging to shoot accurately, and it can be very annoying, especially the loud cracking sound.

Gas Redirect

Well, if you want to make your 30-caliber rifles more comfortable and effective, the V Seven HELIOS-K Linear Compensator is an excellent muzzle device for you. This Linear compensator is designed to redirect the glasses from the muzzle blast forward and away from the shooter, along with the sound signature as well. It is ATF-approved and proudly made in the USA from grade 5 Titanium, so you can be sure that it can handle the blast of large calibers.

Works On Any Barrel Length

The V Seven HELIOS-K’s external diameter is only 1.115 inches. Therefore, it can fit in most slim profile handguards and is ideal for a CQB weapon, especially those chambered in .308 Winchester, 300 blackout, or similar calibers. Still, it can be used with any barrel length, even long-range shooting long range rifles.
