I use Mission Critical on my two tricked S&W SW-22 Victory(s) & my Performance Center SW-22 Victory. All three run as smooth as a well aged bourbon. It also improved my accuracy & it cuts down my cleaning time.

I have been using Otis products on all my guns all the way back to Louisiana duck huts with my Paw Paw Wiltz. There has never been a better brand to protect our Brownings from the wet, muddy and humid climate. From tested time it stood true in quality and performance. Otis continues to develop leading performance products for the modern firearms of today. Other companies come up with products that are good, this is very true. But they pale in comparison to the standards of Otis. Thank you Otis for continued success in product development... Beaux-Dean

If 4 new Henry Rifles could talk each would sing praises to Otis. The best for my best.
