I am currently giving quotes and taking orders for 6MM Fat Rat 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: February 3, 2012
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 & FAT 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.

Reloading
-Chamber was set up so 108 Bergers, 105 Lapua, 107 Sierra, boat tail juncture would be at or slightly below the neck shoulder juncture of the brass. 105 VLD will be approximately .040 above the neck shoulder juncture.
Greg Krebaums loads ( these loads worked in Gregs rifle and are considered MAX ) Not all barrels will handle these loads as some barrels may have a smaller dia <.236
200yds- 70 flat base bullets, I use 26.5 of N130 @ 3000fps, I will switch to H322 when I run out of 130. You might have to trim down the recoil spring to get this load to function with the fast burn rate powders.
300yds- 90 Bergers, 30-31, RL-15 @ 2900+ FPS
-108 Bergers 29-29.5, RL-15 @2750+ FPS
600yds- 108 Bergers 29-30, RL-15 @ 2800+FPS
Lee's FAT RAT Long Range Loads
Start with 1 full grain less than these MAX loads and work up to these, watching for pressure signs. Keep in mind that all barrels are not alike
107 Sierra with 30.0 Grains of RE-15 @ 2825 FPS
108 Berger with 30.5 Grains Varget @ 2846 FPS MAXimum LOADS
108 Berger with 30.0 Grains of RE-15 @ 2825 FPS
These loads will not work with the RAT
Always remember to start low and work up to the MAX loads
Further load testing will be done as time goes on

The Original SR MicroSight, an aiming aid consisting of an integrated hood, lens, and aperture for the AR-15 service rifle.
What it does: Since the eye is only capable of focusing on one plane at a time, and the front sight and target are in separate planes, conventional wisdom says they both cannot be in focus at the same time. Fortunately, Stallings Machine has innovatively extended recent discoveries in diffraction optics to create an aiming aid called the Original SR MicroSight providing multifocal capability. By careful design and fabrication, a single miniature optical element provides simultaneous focus on both the front sight and target.
How it works: The MicroSight is a special application of a more general device called a Phased Zone Plate. The MicroSight attempts to confine the light into two focal lengths corresponding to the target and front sight.
Installation: The Original SR MicroSight hood replaces a standard AR-15 hood (1/4-32 threads) as found on most NM AR-15 rear sights. If you have questions about whether or not the MicroSight will fit your AR-15, contact Stallings Machine.
Application: Users must have good natural or corrected distance vision. It is very important that the user's vision be correct for distance viewing since the MicroSight provides the target image by passing a portion of the light to the eye unaltered. This is of course contrary to the conventional approach of correcting vision to provide a clear view of the front sight. The MicroSight physical parameters are established by the sight radius. A MicroSight designed for a short barreled weapon like the AR-15 will not work well on a Palma Rifle and vice versa.
One size fits all: Once your vision is corrected for best distance viewing, you do not need to select from different MicroSight configurations. A single combination of hood, lens, and aperture is offered to satisfy the needs of all shooters. The aperture opening in the MicroSight is approximately .040. While many shooters use a smaller rear aperture because the increased depth of field helps them bring the front post into better focus, the MicroSight achieves sharp front sight focus without depending on the increased depth of field (and the resulting loss of transmitted light) of a smaller aperture. If you REALLY feel you need something other than a .040 aperture, contact Stallings Machine.
Legality: The hood that houses the MicroSight is well within the size allowed by the rules as they are written.

THE FAT RAT Is the next generation of the 6MM AR-15 Platform Match calibers. This was developed by Accurate and Reliable Rifle with coorporation between Myself and four customers that wanted a little more velocity with the heavier match Sierra & Berger bullets. It is still based of the 6.5 Grendel case, but with improved chamber dimensions that allows more FPS without the pressure problems of the standard Rat and the heavier bullets
