Dale and Kathy produce the highest quality cans and bipods on the market. Ive been doing this for a long time, and there is nothing out there that comes close to Elite Irons craftsmanship and preformance.

I recently received my STFU and have had several opportunities to use it- the name says it all. I bought it for my 6.5CM and I get great repeatable groupings – I could not be happier. The suppressor wrap is a nice touch. This was my second Elite Iron’s suppressor- excellent quality. On top of that, always helpful staff when I call with questions. Thank you!

The STFU is nothing short of amazing. Have been running this on a 5.56 SBR. Dale and Kathy make an incredible product and their customer service cannot be beat.

I have a STFU on my 300 Black Out 9 1/2″ barrel SBR and I can shoot it all day long with out ear protection. It is an amazing suppressor, but I would have expected nothing less from Dale and Kathy at Elite Iron.

I have been running the STFU for over a year now. Definitely the quietest suppressor I have ever been around. Very happy with it.
