Manufacturer claim
- A true multi-caliber suppressor — Thompson Machine states it is very quiet on .22lr, .25acp, .32acp, 9x18mm and .380acp hosts.
- At 4.125" by 1.25" and 3.8 oz, Thompson Machine claims suppression comparable to industry-leading silencers twice its size and weight.
- Uses artificial environment and wipe technology with a proprietary mono-baffle stack that seals in the user’s ablative medium until the suppressor is fired, so it will not run out in your pocket.
- Available in 1/2-28, 1/2-36 or 13.5x1LH thread patterns.
