X7 Fusion Rifle is built using Kaiser shooting products own Polymer upper and lower receiver Platform. Injection molded long and short strand glass infused special polymers for impact resistance, shatter resistance. These receivers can stand up to amazing abuse. With our test rifles hitting 50+K rounds with minimal wear and no failures attributed to the receivers, we stand by our line of rifles with a lifetime warrant.

Utilizing the special polymers, the receivers need little lubrication with a standard BCG and no lubrication when purchasing our rifles with an NP3 BCG.

Our ultralight rifle has a guaranteed Sub MOA accuracy. Standard rifles come with a Faxon Pencil Barrel that has 1:8. These barrels have been treated with a black nitrite salt bath. Nitrite offers exceptional wear resistance, excellent corrosion resistance and a uniform black color. This is not a coating but a surface treatment of the metal that creates an exceptionally uniform surface. This is a more consistent finish than that of a chrome lined barrel and we find it is mandatory on even our entry level rifles and pistols.

This thing is AWESOME!Review by Eric
I have shot a ton of AR-15s, but the Monarch by Kaiser US is by far my favorite. It is incredibly lightweight, durable, and accurate. Everyone who I let shoot this gun at the range is blown away with its weight and performance. There is almost no recoil, and it's super easy to keep on target for quick follow-up shots. I liked my Monarch in .556 so much that I also purchased one in 300 Blackout. This is my go-to AR for sure. I love this thing and highly recommend the Monarch from Kaiser US!! (Posted on 8/19/2016)
