What slide/optic cut is this? Coyote XCarry

578 Views 11 Replies 4 Participants Last post by  Jackal
Apologies, as my interwebbing is failing me today, but damn if I can find anything on the slide my XCarry came with. It has the 6 holes pre-drilled under the plate, but it's not a Legion. It is an "LE" model if that means anything. A friend bought it from Osage in Jan 2021 and then later we traded. Mainly, I'm trying to determine if it accepts the RMR directly without a plate (my research suggests it does). Thanks folks!

It absolutely should those outside forward holes are for the RMR. Springer Precision has a good video and pictures for deciphering the various sig optic cuts.

Yes. That's the R2 optic cut. But the RMR is smaller than the R1P or DPP so you will have a small gap. You can get a filler plate for this and will stop the RMR from maybe moving under recoil and will put less pressure on the mounting screws

I watched a short video and the one I watched didn't have a slide in it with the 6 holes. I thought was the case.

Awesome. I was hoping there might be a filler plate at the rear that adds the rear sights back or a dovetail. The googling continues.

I guess I could get the Bobro plate that has the rear sights and use it. I could likely also likely get longer RMR screws and thread them completely through the plate and into the slide as well. Might make for a really solid lock up.

This is what you will want. Best plate on the market for that slide cut, they also sell a set of sights you use for it.

This is coming from someone who has had the CHPWS plate, the BoBro plate and the FCD plate.

Your slide cut is the same as the M17/18.

ETA: just because it has the holes you will still want the adapter plate. The FCD plate is made so you will NOT need the sealing plate for the RMR. Plate is made from STEEL, not aluminum which the recoil bosses can sustain a significant more amount of load.

Won't work. The thread holes in the BoBro plate are standardized RMR holes and thread pitch while the SIG RMR holes are smaller in diameter and different thread pitch.

The BoBro plate rear sight is non adjustable and what you get is it, cannot be changed.

Dude I've got... 12 ARs with FCD parts on them? Like some lowers I've got $1000 in because of dimple this and Duck that! Love the FCD stuff (even if Roger does get butthurt about retailers selling his stuff on discount). I don't mind one bit spending the money, I just didn't know that plate existed!

Ordering it now.

Now you know, your welcome and congrats!

It truly is the best plate on the market and because of that plate is why I prefer the M17/18 commercial optic cut. Remember, you do NOT need the sealing plate for the RMR with the FCD plate. Proper design went into this unit.
