Adding to cart… The item has been added

The 2nd generation of the Ultra 7 suppressor superseded the last in late 2020. The new version is both quieter and lighter than what was previously available. The Ultra 7 is designed for applications where a compact form factor is needed. You can expect excellent suppression out of this can even though it has a relatively small form factor. There are two options when it comes to caliber. .30 caliber is the best choice if you want the most flexibility, this allows for calibers from .300 RUM and down. 6.5/.243 optimizes suppression but at the same time limits your variety of options quite a bit. The Ultra 7 Gen 2 meters at 139 dB (milspec left/right) and 129 sB at the shooters ear. This was tested with full power M118LR ammunition out of a 20" barrel on an Accuracy International AX. TBAC now specifies the dB rating as one number because of the consistency of the PULSE system that they use for testing. Compared to the older Gen. suppressors the new version is about 20% lighter. 

With the CB mount, the suppressor mates to a conical shoulder on the brake and locks up rock solid and extremely tight. In direct thread configuration, the ULTRA suppressors use a heat-treated 17-4 thread insert and initial blast shield. Like the original, the Gen2 ULTRA is all-titanium and is fully welded. The Gen. 2 is now a "tubeless" design, with the baffles joined directly with no separate tube. The Ultras were designed to be the "ultimate" lightweight precision rifle suppressor. This means we used materials to meet those goals. Titanium, even Grade 5, is ultimately limited by temperature. The Ultras are very strong but excursions above 800 degrees are not good for the material. If you take it far enough above 1000 degrees, it will get too weak to sustain the blast and you would eventually get a failure. We recommend keeping the Ultra series less than 800 degrees. TBAC products are well known for being the best in the industry by shooters around the US. There is not anything else that currently competes the suppression level or weight you can expect out of the Ultra series.
