I watched the video and installed per the spec, but my front sight now had to be moved all the way to the ejection port side for the rear sight to be centered.

The POI was also quite a bit higher than before. Barrel looks perfectly straight in relation to the rail end, though.

I know I lost the two front "torqued" screws when switching to this rail, but there's no torque settings for the four screws in the front now. The rear barrel screws were alternated to 62 in/pounds.

Should I reinstall the rail and use my Aimpoint Zero to save the zero? Also, are there any issues with the bolt and extension being misaligned versus the factory setup?

Waiting for the solution to this as I'm seriously considering an MREX.

Um, I literally sent them an email 4 minutes ago, and they called me to inform me that the bridal that they're threaded into has some variations what they've been seeing is that the screws compress the rail. He said that the screws aren't vital to to rail, and to NOT overtighten them. He's working on getting shorter screws, however.

I'm going to reinstall and barely torque them with vibratite and see how it goes.

So when I added the my MREX rail, I had to dremel some of the hardware that connected my atlas bipod. It looked suspect to me. good luck!

Cheers

Saw this on their website. Guess they don't know what a torque specification is

IS this a problem with everyone who has one of these rails ? I Just bought a Unfired SCAR that was used as a model for a supressor that has one of these rails already installed. I have yet to shoot it but id like to know if I shoujld be expecting iot to be off when sighting it in, or even bother until I back out the offending screws.

I didn't have an issue with mine like this. Between adding the rail, and swapping out muzzle devices my zero should have been way off, but it was only about 3 clicks down with my irons.

I also had an issue with the T20 Torx bolts supplied contacting, and subsequently canting the barrel. Surprised KDG didn't notice this on any of their test guns.

Same here but I believe a member around here mentioned they had to shorten a couple of the bolts to keep from touching the barrel like Stryker mentioned.

Screws for the Magpul M-lock rails or accessories need to be shortened if mounted at the 6 o'clock position and near the gas block. They do not contact the barrel, but without shortening they do come close to the gas block.

This is the only issue I ran into.

Has anyone figured out a rail panel that fits the modular portion of this rail on the sides?
Interested in this too. The biggest downside I have with this rail is that you loose the side rails. For me, that really limited where I could put my sling mount.
