In this episode of TFBTV, James reports from Nellis Air Force Base outside of Las Vegas and gets hands-on with the Delta P BREVIS III SMG silencers for the SIG Rattler in .300 Blackout and the H&K MP7. The Brevis III silencer is 3D printed and, according to Delta P, “surpasses conventional technology and meets the full range of NATO suppressor requirements. Based on the proven BREVIS II, the BREVIS III adds features to reliably suppress machine guns from the MP7 to the M2 BMG.”

The BREVIS III suppressors are smaller, lighter, and more durable than typical machined silencers and are thus more readily able to resist extreme heat and pressure.

The titanium MP7 silencer is only 4.8in (120mm) long and weighs just 8.3oz (235g) with an average sound reduction of 1m to left of muzzle of 28.5dB. 4.6x30mm Fiocchi 40gr FMJ runs at a cyclic rate within approx. 10% of the unsuppressed rate.

The Rattler suppressor is made entirely of Inconel steels and offers similar performance, but weighs about 15 ounces. The additional heft of steel is needed to handle the more powerful .300BLK.
