Fireteam 556 from Exigent Defense on the Surefire Hundred.

FRTs are becoming more prevalent and silencers are becoming easier than ever to get. We’re going to start showing you guys some solid silencers for that FRT abuse.

The material the silencer is made out of is going to be one of your biggest factors. Inconel 718, 17-4 Stainless or Haynes are going to be your best materials for heavy abuse as they have a higher operating temperature than titanium.

Low back pressure vs high back pressure. LBP or Flow Through silencers are going to help maintain a consistent cyclic rate through the entire magazine. You’ll get less gas to the face and keep your r***e running smoothly. High-back-pressure silencers will see a pretty quick increase in RPM, even on 30-round mags which is going to change how controllable that r***e is, increase parts wear and gas to the face. Traditional higher back pressure silencers are still incredibly useful. Tune your r***e, we’ll drop a video on that soon.

Some polonium K at night dude? Hell yeah.

For the size and price the Polo K has really solid flash performance, Especially on a short barrel with a high rate of fire.

Cat KK is a monster! It’s the first silencer we’ve run on a new test host we slapped together and she’s NICE!
