I am setting up the last carbine I hope to ever build. I'm tired of changing gear, I think I have finally settled on the gear I want/need and how I like it setup.

This carbine will be a DD 14.5" LW with a Troy 13" alpha rail (no sight). I wanted the lowest possible profile for the light (scout m600c) and laser (LDI OTAL IR). I have direct mounted a lot of gear in the past, but never in this configuration. it's getting finished with a Swarovski Z6i in a LT104.

I wanted the ability to switch shoulders and have the same grip, so everything needed to be mounted as far forward as possible.

I use the direct mount VFG as a hand stop only. I really like this configuration of MVG with the Troy rail, they blend together perfectly.

On to the instruction. Planning is key, mockup where you want everything to sit and make sure you will have no interference between parts, your rail, or your muzzle device. Spend a lot of time doing this. These cannot be removed without taking the rail off, I had QD on everything except optics. I'll never understand QD light mounts. I'm sure this isn't for everyone. I just wanted to save weight and bulk.

For the scout series lights, (on a TRX) you will need to square the round holes. This can be done with a Dremel, but best with a mill. Make sure the light sits snugly inside the new cuts and rests evenly with the rail.

Next, take one of the new Troy backers ( they made 2 versions, 1 with a locating rib, the other just rounded. ) for the scout / TRX combo, you will need the rail without the rib.

Drill out one hole to allow the proper screw to pass through it freely. Next, drill a second hole that lines up with the threaded hole on the scout. Now screw the light into place from the back. Make sure your screws are not too long to bottom out, but not too short. Check fit, and the loctite.

For the laser, you will need to mill ( or very carefully file) a flat between two of the outer ribs until the laser can rest with some good surface contact. Next you will need to enlarge the areas for the screws to fit. I made it tight so the flats and screw enlargements would capture the laser linearly during recoil. I also used a ribbed backer to help keep the laser aligned as the laser body does not extend into the rail like the scout light.

Use the same backer modification and mounting instructions.

It came out well and I am happy with the results, now just to wait for the upper and optic.
