The 30BA was discontinued May 2014 and replaced with the 30CB9. Click here to proceed to the 30CB9 specs page. We will continue to support 30BA-series customers. 30BA brakes will remain for sale. 30BA and 30BAS suppressors may still be ordered on a special-order basis for customers already invested in the 30BA system.

Brake-attach .30 caliber suppressor

The model 30BA is the brake-attached version of our flagship long-range precision rifle suppressor. It offers best-in-class sound suppression levels in a very light weight format, and is built with accuracy as its first priority. The 30BA is designed to mount over our muzzle brake. It is particularly suited to applications where the rifle will be shot suppressed and unsuppressed, and a brake is desired when shooting without the suppressor.

We developed the 30BA and 338BA to meet the requirement that some customers have for a suppressor that mounts over a muzzle device. We haven't found a "quick mount" on the market that meets our accuracy and repeatability requirements, so we developed the BA series to mount over our brake and provide the same repeatability as our direct thread attach suppressors, like the 30P-1. The 30BA features a conical shoulder for rock solid POI repeatability and to make sure it never comes loose.

The 30BA was designed around .308 for maximum flexibility and is rated up to .300 Winchester Magnum, but it's the ideal suppressor for the most competitive mid-sized cartridges for long-range shooting such as .243 Winchester .260 Remington, 6.5 Creedmoor, 6.5x47 Lapua, 6.5-284 Norma, and 7mm Remington Magnum & WSM.

The 30BA uses the baffle stack of the 30P-1, which has racked up impressive results at long-range field shooting events in the Rocky Mountain region, including the Blue Steel Ranch Steel Safari and the NRA Whittington Center Sporting Rifle Match. Many long-range shooters prefer shooting suppressed because the muzzle blast and concussion is eliminated, while the recoil impulse is reduced and smoothed out over time. The net result is that the rifle is easier to shoot and it's easier to make hits. Communication with your spotter is easier because the need for hearing protection is reduced.

The 30BA is constructed of titanium with a fully-welded baffle core. This material and construction provides a great strength to weight ratio. It can take whatever your precision rifle can dish out.

The 30BA brake will accept the 338BA suppressor, so with a .30 caliber brake on your .308 and a .338 brake on your .338 Lapua Magnum, you can use a single 338BA suppressor on both. The 30BA suppressor will not fit on a 338BA brake.

The 30BA is ideal for: long-range practical competition shooters; varminters; predator hunters; precision tactical shooters.
