Review: Otis 7.62MM MPSR Cleaning System

Otis 7.62MM MPSR Cleaning System with cleaning brushes

If you have a .308/7.62 caliber rifle and need a comprehensive compact packable cleaning kit for the field then the Otis 7.62mm MPSR Cleaning System is an obvious choice, however there is more to the Otis cleaning kit than just size.

A very compact kit that delivers all the benefits of a large deluxe cleaning kit.

There has been a trend in the market away from long screw together rod based cleaning systems to pull-through designs utilizing cord or some type of nylon sheathed aircraft cable. The Otis MPSR Cleaning system is the later based on their Memory-Flex cables. The reason the industry is moving away from traditional rod based bore cleaning systems is that they can be very hard on the barrel and rifling which ultimately impact accuracy. The less a metal rod is banging down the bore the better.

Another reason the Otis system can decrease bore or crown damage is that the Memory-Flex rods flex during use which means the user is not torquing a stiff rod against a crown or breech edge. Pulling the Otis cable through the bore also delivers a more even cleaning because a patch is pulled and not compressed against the cleaning rod. When a cleaning patch is pushed down the bore it compressed unevenly against the cleaning rod and leads to unevenly cleaning. The Otis system just drags a uniformly tight patch down the bore which also cleans the breech area more thoroughly as well.

What I liked about this cleaning system is that it works really well and can be the same easy-to-use compact system you use in the field for a quick cleaning or a detailed bench cleaning at home. You still have all the same level of quality cleaning tools without any added bulk or need for additional cleaning equipment.

Final Thoughts

Otis makes and assembles all of their products in the USA. If that wasn’t cool enough, they are also family owned and operated as well. I love rooting for the little guy when they are doing all the things right. In this case Otis is delivering an affordable, compact and extremely high quality cleaning system that has a place at home or in the field for the .308/7.62 NATO shooter.
