Will the RMR bridge be drilled for multiple different optic choices or strictly for an aimpoint, @karagias ? Little birdie told me that Santa is dropping an M-brace off for me.

I have had my m-brace for two weeks now. 1.5(38mm) height and 34mm tube, 10moa. Absolutely awesome mount, and I have spuhr's, mpa, and eratac multi-cant. The level is my favorite I've seen. The no twist of scope mounting and the single bolt clamps really make setup a breeze. I've got it on a 338lm with a Kahles k25 and it so far seems perfect. I love the ability to see the level so easily. The only thing I'd like to see in the future would be a 34mm height and a version with a little wider spread of the rings for scopes with longer main tubes. Other than that, great job on this mount. I recommend this to anyone.
Well, Ive read through this thread a couple times and researched other mounts (NF, Spuhr, Seekins, Badger, etc..)for my AT-X and couldn't find anything that seemed comparable to the M-Brace. So, I pulled the trigger tonight and ordered one, hopefully it shows up before Christmas so the wife can wrap it for me!!! 
Ted, thanks for the informative post and responsiveness to everyones questions and comments, that is what sold me on the mount for sure!
Can't wait to get it on the gun!

no. I got an email they are waiting on some parts from their anodizing vendor, who was a couple weeks out iirc. worth the wait.
I called yesterday and was told the one I needed (30mm/1.5”/10MOA) was in stock. Just got a shipping notice for it this am as well. So they have stock, maybe not the exact configuration you’re looking for. 
Waiting for Brownells to get them in. Have a bunch of giftcards to use em.
I'm thinking there's something wrong with my new Wheeler Fat Wrench. I cranked it up to 55 in/lb to mount my mbrace, and I'm cranking on it hard and it won't even click. This is my first torque screwdriver and it just feels like it requires a substantial amount of torque.
This was only on mounting the mount to the pic rail. I haven't torqued anything down on the scope yet until I know the torque is right on my screwdriver.
Anyone have this issue with the Fat Wrench? Do I need to bite the bullet and get an American made torque screwdriver? Or am I just being a pansy ass and need to crank down harder on the mount?

For those kinds of torque wrenches, make sure you untorque it when you store it otherwise you're going to break up the calibration.
55 in/lbs is a good amount of cranking, but not that much...
Well.. I must have not been as good of a boy as i thought b/c Santa didn't leave an M-Brace for me under the tree.. Instead, i believe he left a stick and a dog turd. SOOO... i ordered one the other day. Just got the email that it wont ship for a couple weeks due to anodizing being backed up. Oh well.. Spoke with Bella, who was a sweetie pie, and got her to switch my order to the 1.5" high mount anyway so no biggie. She also hinted that there are a couple of accessories that are "done" but not released yet. Here's to hoping its an RMR bridge. 
Excited to get the mount.

Brilliant, been wanting an ARC M10 QD-L with the ability to add attachments for some time, had to get a Spuhr just to work with my PVS-9 SIMRAD.
Ted, you mention some new mount options coming for RMR, etc. Any chance you can make a LRF mount with removable picatinny, where you can swap the picatinny with RMR, DeltaPoint, Aimpoint, etc. plates, how about having plate mounting positions at 45 either side?
Did you design this mount base to STANAG 4694 spec?
You had to ask for a QD version, didn't you? Would you settle for a T-handle wrench on a lanyard? Just kidding.
QD is kind of a bitch on a Pic rail. The only two QD methods that I like are thumb screws, like we did with the QD-L, and the levers from American Defense and I think those guys sell to other OEMs. Nevertheless, for a bolt action rifle having potentially very heavy recoil, I really prefer screws. Screws just work every time and you would never be able to match their clamping forces with a lever that would fit on a scope mount. We've considered QD. Give us a PO for a few hundred of them and I'll do it
Some of us love QD, but I agree, it needs to be done right. I think the QD in the ERA-TAC is one of the best, I also like the new Spuhr QD. I also liked your wheels with the QD-L but I think a lever has a better chance of putting close to the same torque back than my fingers can do with the wheel, I was always suspect of RTZ if I didn't put quite the right amount of pressure when attaching the scope again, that being said I always checked zero after remounting a scope, just habit I guess.
OMG YES! Marlin has their "tactical" line, but would love to see something from a Karagias brainstorming session.
Finally got here. This thing is a piece of art. Well done, as usual, ARC.
For some reason I have an itch to sell my spuhr mounts and buy two of these. And some how pocket cash?!?
Really liking my ARC Mbrace with my ZCO. It’s a really good alternative to the Spuhr mount. If you don’t need all of the attachment options with a Spuhr, I’d highly recommend it.
I just ordered a 34mm 1.26" with pic rail attachment. Will be installing a new 6-36 razor, and a sendit level on the pic rail.
Once the HUD and LevelIt mounts come out... This is exactly what I'm going to do.
All I need is an RMR bridge. I'm a simple man with simple needs.
Does having a rmr(or similar device) atop your optic give a whole lot of advantage for field/prs comp style shooting?
Makes a small difference in target acquisition. Point the red dot where you anticipate the target to be, and then when you drop down in your main optic, it should be right there. It's faster than powering up/down in magnification; you can do the same by indexing the turret, but the red dot is faster.
Thanks for the info. I usually run on 10-12x for matches and haven't had much of an issue acquiring the proper targets quickly. I need to get behind someone's rifle that has one and try it out. See if i could run at 15-18X and acquire targets at same speed with the rmr.
I usually keep my main optic at 18x and use the red dot to index on targets. It works really well for me, and I like the extra magnification for aiming on specific points on a plate, vs. aiming generally at a plate. It's pretty quick once you get used to it, especially on longer range targets and if your NPA is solid.

For some yes. Others no.
I just look over my optic and put landmark or target on top of optic and then move into sight picture. Red dot didn’t help me any. Tried a bunch.
Others though, it’s the opposite. They see a big increase in target acquisition.
Try it. With a quality red dot, you’ll get most of your money back if it doesn’t work for you.
Also, it looks cool and chics dig it. So, I mean…..

I know right! Cuz we all pull so much tail at the matches! On the pro rodeo circuit we call em buckle bunnys. What should we call em here, brass booty?!
Love it! I'm not a great shooter, I finish 30th something place typically at PRS/NRL regional matches in PNW. There was a girl in squad behind me, total dime. She had me by 13 pts at end of second day. She'll very likely be sponsored 22 season.

I ordered direct from ARC, they sent me a tracking number when it shipped.
Okay thank you, I ordered a few days ago... just me being stoked and impatient....
As always, very nice. 
Holy shit what do you zero at? Most rails have 20 Moa built in... What are you shooting where you need 80 MOA?
Ordered my 34mm 1.25" M-brace on Sunday, received today. Mounted up the new gen3 razor. I have my origin action installed in a Xylo chassis. Put a bubble rail atop my scope rail, it matched the integrated bubble on the xylo. Installed and torqued the M-brace, it's supplied level is a half bubble off from my Xylo level. So it's not mounting level to the pic rail. Removed bubble from M-brace, installed bubble level on scope tube. The mount is grest in all other aspects, I have many sets of arc rings. I also purchased the side mount pic rail to install the send it level, however it interferes with my hawk hill dope card. Need to fix my first world problems and come up for a solution for all my booshi ass shit I guess. Just cuz I want to look cool AF at matches I'll prob install they're hood mount for a rmr once that comes out, cuz its just money right? Get me some them barricade bitches to hang from my schween next big 2 day match. Not cuz i finish 27th place, but cuz my rig look so tight. Did I mention I love moonshine? I do.......
Received my M-Brace, looks very well machined. Anyone know what the 3 holes drilled out in the bottom are for? The way they are drilled they look like they are there for more than weight reduction but nothing in the manual about them.

There is a joke here…somewhere…
…sorry, go back to regular programming
Just want to say awesome job on another great product @karagias!
Anecdotal testament to ARC's machining quality.
I just finished building a new comp AR in 6ARC & had to play musical scopes. Pulled a MK5 3.6-18 off my 6.5C bolt gun (Nuke with 20moa rail, Xylo, & ARC M10 medium rings). Put that scope in a 1.5" 20 moa M-Brace on a VLTOR fusion.
Sighted in yesterday, elevation was dead nuts same. Windage was just .6 off. I was zeroed in 3 shots.
Very impressive!

Mine should be in tomorrow!
Is anyones level off? I leveled my scope using a SAC level and a plumb line, and I double and triple checked it on my RRS tripod and a send it level. I can get all three to match up and the ARC level is still off.
Not a big deal but I figured I would check before it goes in the trash.

I used the bubble on my arc chassis, it matched the bubble layed across my scope rail. Installed M-brace, M-brace bubble wasn't plumb to the other two matching bubbles. Threw M-brace bubble in box and installed a 34mm tube level.
Thanks, at least I’m not the only one then.
