Being designed primarily for Close Quarter Battle situations, all of our mounts are specifically designed and intended to have, a slightly upward angle of about 5 to 10 degrees when correctly installed.
This angle is a functional necessity of the design to allow for the correct alignment of the sights to be nearest the center of the light beam at 15 to 20 yards.

5 out of 55 out of 55 out of 55 out of 55 out of 5 BLAM-R Great Product , 10.17.2021
Reviewer: Ruger Guy (, WA)

I bought two BLAM-R's. They are of the highest quality and fit perfectly. Personally, I think they should be Ruger OEM accessory parts. Also, Dan's customer service involving production and availability was great. Thank you.

5 out of 55 out of 55 out of 55 out of 55 out of 5 The ONLY MOUNT for RUGER AR-556, 12.7.2020
Reviewer: Alan G (Atlanta, GA)

I have looked for months for a mount like this for my AR-556 and finally found it. The workmanship, finish and fit is very well done . I got one of the "Type B" versions which was modified after they had already made them for the "A". The modified cuts are clean and hardly visible. The upward angle of the mount bothered me at first, but when I mounted my INFORCE WMLX Gen2 on it, it is not even noticeable and the light is dead center on the target. 5 stars for this and thanks you to CDP.


5 out of 55 out of 55 out of 55 out of 55 out of 5 Best Iíve ever used., 9.16.2020
Reviewer: T.L. (, MI)

The adapter I received was absolutely flawless in appearance and well packaged so it wouldnít get damaged in shipping. It went on my AR556 perfectly and when I tightened the set screw it was rock solid. I mounted a light and my sling on the adapter and itís just rock solid. Itís very light weight and you donít even see it when youíre shooting much less gets in your way. I highly recommend this to anyone who has a Ruger AR556 because this adapter requires no modifications to your rifle to install. Iím very pleased I found this mounting adapter before I started to change the configuration of the weapon when itís not necessary. Thanks for this exceptional product.


5 out of 55 out of 55 out of 55 out of 55 out of 5 Really Great Product!, 7.10.2020
Reviewer: B.W. (, KS)

This is a really great upgrade for the Ruger AR-556! I wanted to add a rail to install a flashlight, without swapping out handguards or losing the front sling mount, and this is the perfect solution. Itís an ingenious design, well-constructed, and took just a few minutes to install two of them on two separate rifles. Itís big enough to serve its purpose, but not so big as to be obtrusive. I had researched some other solutions before I found this, and I definitely made the right choice!
