I recently completed a review of a Rock River Arms Coyote Carbine .223 Rifle that I borrowed from my brother-in-law. He purchased the Burris AR-P.E.P.R ™ Mount to mount his scope on his rifle, so I decided that this would be a good product to review also. Normally I like to add photos of the packaging and everything in the box, but since all I received was the rifle with the mount already installed, I had to make the best of it. You can purchase this mount now from Midway USA for $69.99 plus S&H.
To start off the review, the description below in italics is the information directly from the Burris website along with a photo and the technical data. This mount comes in two different models, 1" and 30mm. The model being reviewed is the 1" model since it is used to attach a Nikon Coyote Special 1" tube scope. I would expect the 30mm to be extremely similar.
Proper Eye Position Ready for combat rifle scopes, this mount provides 2" of forward scope positioning on the M-4 and AR-15 platform. Ring bases are milled as a single, tough unit, and ring tops feature Picatinny tops for mounting additional accessories.
Weight A B C D E
1" 8.3 oz. 1.0" 1.60" 2.44" 4.17" 2.15"
30mm 8.7 oz. 1.0" 1.75" 2.67" 4.17" 2.15"
Since I'm never satisfied with only showing the manufacturers photos, I had to include some of my own. This series of 6 photos below gives you a close up view of each side of the mount. Remember that if you click on a photo it will bring up a higher resolution photo. One thing you will see in the photos is that this mount comes with integrated Picatinny rails on the caps. I see this as a plus, especially for those who may be considering using these mounts on a rifle that does not come with other accessory rails. Also you should notice that all the parts are thick which translates to ruggedness. Each cap is attached with 6 screws. I'm sure that 4 screws per cap would be sufficient for the average user, but the added screws help to provide strength for rough conditions. The mount also comes with an allen shaped torx wrench. The torx head configuration of the screws allows for more torque with less chances of stripping.
When you disassemble the mount to the level needed for installation, it breaks down into these primary components below. You get the base assembly, two caps and 12 screws. The body of the base assembly and caps are made from aluminum while the rail attachment plate, rail attachment bolts, nuts and cap screws are made form steel.
The mount weighed in at 0.53 pounds (8.48 ounces). This is slightly heavier than the 8.3 ounces advertised for the 1" ring model.
When the mount is installed on the rifle with the scope adjusted to an eye relief position that is natural for the shooter, you can see below that the offset position of the forward mount is needed since the mount is forward of the upper receiver rail. I installed and torqued the rail attachment nuts and cap screws to Burris's recommended torque per their instructions. I'm glad that Burris provided this information because I feel I have a tendency to under tighten critical components due to the fear of stripping threads.
When you consider the price, ruggedness and added rails on the caps, this mount represents a good value. If you have sufficient room on your upper rail to use a two piece mount and are weight conscious, you may want to consider another mount. This mount was in no way a lite weight system, but the additional mass only adds to the ruggedness. Would I recommend the Burris PEPR Mount? Actually I already did recommend this mount to my brother-in-law before he purchased it. I have an engineering buddy of mine that did quite a bit of research into mounts and he found that this was one of the quality/value choices on the market. After he showed me his research, I had to agree. My personal opinion is that this mount looks great on a AR style rifle. You can see it below installed on a Rock River Coyote Carbine with a Nikon Coyote Special Scope.
