5 out of 55 out of 55 out of 55 out of 55 out of 5 Product is perfect for an AR light mount, 12.29.2015
Reviewer: BLGrady (, KY)

I purchased two of these mounts, one of the BLAM with rings and one of the BLAM2, without the rings. Both fit perfectly on my rifles and accept a vertical foregrip, several types of lights and a Harris bipod. Flawless, easy installation and very steady, no movement or rattle. The quality is clearly evident when you handle them and also in use on the rifles. I cannot say anything negative about either mount. First class product and 5 stars all the way.


5 out of 55 out of 55 out of 55 out of 55 out of 5 BLAM2, 2.4.2015
Reviewer: Aaron Bowie (Sanford, FL)

Very nice quality product. Very easy installation. I installed this on my AR15 with a carbine length MOE hand guard. I'm using it to mount the stream light TLR 2s. The unit mounts very solid and puts the light in the perfect spot. This mount would also work great with a rail mounted bi-pod. Shipping was super fast, ordered it on a Sunday and received it in FL on the following Wednesday. I will definitely order from Custom Defensive Products again.

5 out of 55 out of 55 out of 55 out of 55 out of 5 Perfect!, 3.24.2013
Reviewer: Patrick Smith (Norco, CA)

The BLAM2 is very high quality, it looks like it grew on my Colt LE6920.
The color match is perfect. Don't be fooled by the Airsoft clones, this is worthy of a Government national stock number.
Using it with a Streamlight M3 for the moment but easily strong/solid enough for a Bi-Pod or more substantial light system(to come soon).
I looked at the alternatives, do yourself a favor, don't waste $25 on junk, spend a little more and buy professional quality.
Your life(or mine) may count on it.


5 out of 55 out of 55 out of 55 out of 55 out of 5 Great item that fits perfectly, 2.3.2012
Reviewer: MSgt A.C. (Albuquerque, NM)

This one fits exactly as stated.
Initially, I tried a CAA from another site and it didn't even come close to fitting my Bushmaster.
This low profile design firmly fits, lines up, and I highly recommend it to anyone.
Don't be fooled by those other brands.

Ask a question about this product.

Q: When I mounted the BLAM on my rifle, it is not parallel with the barrel.
It seems to be tilted upward toward the muzzle.
Can I get one that is aligned evenly with the barrel?

A: Being designed primarily for Close Quarter Battle situations, both of our mounts were specifically designed and intended to have a slightly upward angle variation of about 8 to 10 degrees when mounted.
It 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.
The angle may vary slightly, depending on the manufacturer of the front sight base casting.
This alignment was tested using the SureFire X200A the X300, Streamlight TLR-1 and TLR-2, and the Insight M3 and M6 Tactical Illuminators.
This incorporated angle also allows for correct centering and zeroing of a laser such as on the Streamlight TLR2 or Insight M6.
If the mount remains parallel with the barrel, ANY laser mounted on the BLAM will not have enough vertical adjustment to easily bring the dot into alignment with the sights.
If it is mounted parallel with the barrel, the light will be too low on the target, below center of mass.

If you insist on having the mount parallel with the barrel, you would need to elongate the holes in the sight base clevis UPWARD, where the rear screw replaces the sling loop.

You might also have to remove material from the base of the sight tower on either side of the clevis, where the mount would contact the base, depending on the manufacturer of the sight tower itself.
When the mounts are attached to the rifle correctly and a light is attached to the mount, one does not typically notice any difference in the alignment.

If you are more concerned about how the mount "LOOKS" on your rifle than the practical functionality of the well planned, affordable design, perhaps the BLAM or BLAM2 is not for you.

Q: I have read on several forums that mounting a light at the 6:00 o'clock position on my AR will cause the light to cast a shadow on the target.
How do you address this concern?

A: Thousands of Law Enforcement Officers and operators who use these mounts, will disagree with that statement.

Mounting a weapon light on your AR at the 6:00 o'clock position on the Bayonet Lug is IDEAL for close quarter engagements out to 25 yards.

First, access to the light switch is immediate and right at the position of your support hand on the forearm of the rifle.

Second, the truth is, any shadow cast by a light mounted on a BLAM or BLAM2 will be well above the target and out of your line of vision.

Your ability to FOCUS on the front sight and the target should be developed with proper training and practice.
When you do, you won't see anything but the target.

Third, mounting lights or other items on either side of the sight tower only obstructs the line of vision covering the target. That is more of a distraction than any shadow.

Also, the size of any shadow depends on the diameter of the beam being cast by the light.

Ideally, you want a powerful, narrow beam with a bright center to illuminate the target.
The wider the beam, the more shadow will be cast.
