Direct mounting a laser

I was prepping a gun for an upcoming class and was trying to decide where to move a laser. I wanted to use a Specter DR for the class, however the laser blocks a good portion of the field of view. I tried a few different options and finally settled on this.

I have an insatiable need to modify perfectly good kit and am a direct mount advocate. If I can reduce weight, but complexity and make things lower profile, ill do it.

I measured the 17s interface, chucked up a cutter, indicated and got to work. 8 minutes later I have this...



The rail is still usable for that location, I did not create weakness or in any other way destroy the rail.



The laser is much lower than it was before, I havent mounted a DR yet, but it should be completely out of the field of view, if not, it will be very minimal.

I save very little weight, but the setup is very low profile. I need to remove the pressure switch to change the battery, but thats a non issue.

I switched from a PEQ-15 to a Class 1 OTAL for several reasons, suffice to say it just fits my needs better.


Starboard Side


Port Side


Front, I checked it under nods, no splashback.

My night shooting time was always very limited, and much more nowadays, so a cheaper, less feature laden IR laser made sense.

Direct mounting it in this fashion made even more sense.

Ill be using Unity Tactical prototype iron sights for the class, so I will need to get rid of the pressure switch and flop the light to the port side with a clickly, but this setup works well.

Great idea, I am going to look into this myself for my DBAL-I2.

do you have a before pic to compare?

My DBAL-I2 is on top of the front rail and it interferes with the Eotech 1X about the bottom 20% but does not interfere with the reticule at all, with the 3X Eotech Magnifier it also does not interfere with the reticle at all.



I will look into this though...

Here is a before picture, its not mine, and I think the LDI mount is slightly lower, buf it should give you an idea of how much lower this mod gets it...



Should be about .35" lower.

Goteron that is extremely cool and it looks like the rails that were cut into are even still usable. Well done.

Saw this over on another site, pretty slick. What does the underside of the laser look like? For some reason, I thought it was flat.

W/ the gas tube so close to that area, how difficult was it to attach or remove this thing?

With how easy it is to remove the Troy handguards I'm sure that it's not that bad.

Looks great! Reminds me of the integral PAQ-4/PEQ-2 mounts that KAC and ARMS used to have for their rails.

Never heard of this. Any more info?

Old-tech stuff.

The "notorious" ARMS #38 SPR-2-3 PEQ sleeve used on the MK 12 MOD 0 is so designed so that the front section is an integrated AN/PAQ-4C / AN/PEQ-2 (A/B) mount:



The railed section behind could be removed for installation of the LAM. Ironically, you very rarely see LAMs mounted in this position on the MK 12 MOD 0, because they would interfere with the bell of the scope under most circumstances - nevertheless, it's what it was designed for...

My understanding is that part of the reason for the Bi-level ARMS SIR was also to allow for a similar adapter to be used with the SIR, though I can't find photos of it at the moment.

Early KAC RAS 2 prototypes had a similar integral LAM mount, though they did not carry over to the production design:






During the RIS II trials where KAC competed with their early URX design, there was a similar concept, though not integral, but that was designed to mount the LAM lower than a railgrabber mount would by directly interfacing with the LAM and handguard:










Compare the AN/PEQ-2A height:






However, for all intents and purposes, once the LA-5/PEQ and AN/PEQ-15 became "the standard" for both SOF and conventional forces, because of its integral mount, these "direct mounting" options all became kind of pointless since they were no longer compatible with the new generation of LAMs.

I have always thought that a step down in the rail at the front would allow a PEQ15 or 15A to sit really low.
It would allow for an over the top grip without blocking IR illumintaor.
It would negate the need to modify your grip when going from day use to IR use.

Quick question, how hard is it to access the battery with the cap that close to the rail? The one thing I really dislike about my DBAL is how difficult it is to open the battery compartment.

It's not bad at all to get to the battery.

You need to remove the rail to mount the laser.

When you put the dbal I2 or similar ir/laser unit that far back on the rail and low....i am wondering if it will bloom or reflect off the gun when you have the pvs 14 mounted on your head or gun?

Anyone know? I have always put my ir/lasers as far forward as possible.
