My Ultra 7 CB is the best can I’ve ever owned and I have more than a few stamps. It’s light, it’s quiet, there’s absolutely ZERO shift, it locks up tight, and never backs off. It’s all I could ask for in a can. I’ve even used it on some AR’s and experience less blowback that with my cans designed for AR use.
I’ve got a certificate from them that I picked up from a prize table that I’ll be using for a second Ultra 7 CB or maybe a Ultra 5 CB.
BTW if you watch the classifieds on snipershide certificates will pop up for sale and can save you a few bucks. 50% certs normally go for $300-$350 and free certs around $800.
