MATCH RIFLE PRODUCTS
I am currently giving quotes and taking orders for 6MM Rat and 6.5 Grendel Match uppers. It is necessary to give quotes because of fluctuations in market prices and availability of parts.
Your imagination and your budget are the only limiting factors in the design of your upper
6MM Rat case on left with 107g Sierra
6.5 Grendel case on right
This page was last updated: September 4, 2010
Developed by Greg Krebaum in Kansas, the 6 MM Rat is based on the 6.5 Grendel case necked down to 6MM with the neck blown forward aprox .075 at a 40 degree angle.
This rifle is built on an AR-15 flat top platform with quality American manufactured parts, the 6MM bullets have a very good B.C. The 6 MM and 6.5 caliber bullets have been dominating competition shooting the last few years. Why not get with the program and start shooting the equipment that will perform the best
This upper is built to utilize a service rifle lower, for those that would like to shoot both Service Rifle and Match Rifle competitions and not have to own 2 separate lowers with 2 different trigger weights.
It has tested to be sub 1/2 minute of angle with the 107 G Sierra bullets.
Dies for the 6MM Rat are sold by Greg Krebaum

6MM Rat Information Guide
History of the cartridge-
I had seen other 6mm Grendel Improved cartridges out there but there was not a source to just buy a barrel and parts to build your own. So I decided to design my own reamer and have a set of custom dies made for it. I had done this before for an AR-10 project that I did in a .243 wildcat cartridge. Lonnie Hummel of Horndays custom dies is very knowledgeable and helpful on this kind of project.
I worked out the reamer print for the 6mm RAT with the help of Lonnie Hummel from Horndays custom dies, John Hollinger from White Oak Armament and Dave Kiff from PTG. The reamer was designed to be used with Alexander Arms 6.5 Grendel Brass and for a gas gun. The dies were also designed for a gas gun. After the reamer and dies were made, John Hollinger sent me a test barrel to do the initial testing and everything looked good. John Hollinger asked me if it would be alright if he chambered other customer barrels in this cartridge and suggested I have a batch of dies made up for the cartridge.
I designed this cartridge initially for myself, but others have wanted to use it. I am glad to help other shooters and pass on the information that I have learned.
