The Defender is on my 7.5" AR duty weapon and is so compact that I don't even know it's there other than how much it quiets the shot. My partner and I both came to appreciate it during in-vehicle ambush live-fire training scenarios, especially for the minimal smoke and blowback.
It's also my go-to on 224 Valkyrie for nighttime feral hog eradication. I can often take the shot without disturbing the rest of the sounder.
People are often amazed by the Defender. I've used and experienced other suppressors, and the Defender beats them all!

I bought this suppressor (Defender) for my Ruger 10/22. and I love it. The Ruger has a carbon fiber barrel with a rimfire rifle scope and Hogue stock. I thought the suppressor would make the rifle muzzle a little heavy but after it was attached I was very happy how it felt. After an email session with Mr. Roy Couvillion, I purchased some standard velocity ammo and started shooting. Wow what a difference. I was able to shoot while my wife was sitting next to me on her cell phone and didn't bother her one bit Disassembly and cleaning is a breeze, thanks to the simplicity of the design. Mr. Couvillion was quick to respond to all my questions, which means a lot. Can't begin to tell you how much fun I am having shooting and am shooting more now than ever. I can say this purchase was definitely worth it. Thanks to Mr. Couvillion for his product, Mike Moore for his recommendation, and to Justin at Dave's Gun Shop for all his help. I hope to be able to purchase another suppressor from Acadian Armament in the near future.

It really surprised me how well it works on a 7-3/4" Primary Weapons piston upper. I know I told you I was skeptical about how well you said the Defender performed on 7" guns but I’m now a believer.
I cleaned mine right after shooting it, one really nice feature is that you can very easily clean this suppressor.
Thank you for a great product and I can’t wait to see what else your creative mind produces.
Good Shooting,
Mark
