Did you know...
We have our Class 3 SOT?
That's right, you can get your sound suppressor or short barreled rifle (SBR) from us. Military and Law Enforcement can acquire their burst or auto rifle or lowers from us.
If you are in Montana and make a trip to Kalispell, wecan build your SBR here locally, and you do not need to engrave your lower, since we are the manufacturer. Call or email us to order your SBR.
Looking for a suppressor? We can set you up with many great suppressors, from pistol to rifle, bolt gun to semi-automatic. We can set you up with an EliteIron, Gemtech or YHM suppressor in 9mm, .40, .45, .22, .30, .338 up to .50 caliber.

Pictured above, a YHM Phantom 5.56 Sound Suppressor.
The proven performance of YHM's Phantom Flash Hider eliminates 99% of muzzle flash while the Sound Technologies baffle design (U.S. Patent #7,073,426) reduces muzzle noise by up to -35 dB. The fast attach design (Patent Pending) allows you to permanently install the Phantom Flash Hider and then install the Sound Suppressor without the use of tools when sound suppression is desired. Our patented Phantom Flash Hider system holds the sound suppressor firmly in place by hand tightening and allows the sound suppressor to be removed by hand when no longer needed. A patented gas seal keeps the threads clean so the suppressor will not bind, making removal a breeze. The Phantom Flash hider supports the sound suppressor in two places making misalignment nearly impossible, even if the sound suppressor is not fully tightened.
