Thunder Beast Arms Corporation [TBAC]

The 30BAS was discontinued May 2014 and replaced with the 30CB7. Click here to proceed to the 30CB7 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, short.

The model 30BAS is the seven-inch "Short" version of our brake-attach 30BA suppressor. It is two inches shorter and three ounces lighter than the 30BA. It only gives up approximately 2-3 dB suppression for a noticeably smaller and lighter format. The 30BAS 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.

The 30BAS shares the same mount as the 30BA, which was developed 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 30BAS features a conical shoulder for rock solid POI repeatability and to make sure it never comes loose.

The 30BAS is ideal for competition or hunting rifles when the absolute suppression level is not as important as having a smaller, compact suppressor. It was designed around .308 and similar capacity cartridges such as .243 Winchester .260 Remington, 6.5 Creedmoor, 6.5x47 Lapua. It is strength-rated up to .300 Winchester Magnum.

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 30BAS suppressor will not fit on a 338BA brake.

The 30BAS 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.
