Thanks, I'll call tomorrow.
With the fortis having an inside measurement of 1.34 and KAC at 1.55.
Would the top rail still line up ,with the upper rail?
Sorry, but my experience is limited
The AR15 rail height is standardised, unlike the AR10 (what a pita). This means that the height on the rail for an ASA, Colt, DPMS, ATRS AT15, Dlask, NEA, KAC, Les Baier, etc. etc. etc. should all have the exact same height from the center-line of the bore to the top of the rail on the receiver. This is what makes those rifles so fantastic is that because of this standardisation the interchangeability of parts is so simple. We would have to be crazy to give the Modern Varmint a different rail height from bore than all of the AR15 furniture that it's meant to utilise. So as long as the rail on that URX lines up with every brand of AR15 upper receivers top rail out there, it'll line up on a MV.
The only place we really come into fitment issues with handguards is they're either too narrow for the gas block or barrel contour, or more commonly, they have 'alignment tabs'
The reason being is our uppers on the varmint/hunter or even our AT15 do not conform to the thin-walled forged receiver profile. We make them a little thicker for extra rigidity, which is quite common in billet receivers. On a handguard such as the samson it's not difficult to simply cut off the tab and install it without a tab to index the rail. On something larger like the Rainier, it's more difficult to remove such a large slab off the side of the handguard in an aesthetically pleasing manner.
Well receive my MV today, I waited by the window from 8 am to 3h45 pm!
First of I am very happy ! I love the look, the feel and the handling. Pictures then observation
First picture : naked with Fortis handguard, mft minimalist stock and hogue grip: 6 pound 10 onces ( no mag)
Then as configured with loaner Leupold vx-r 4-12×40, aero precision mount and 2 small keymod rail: 7 pound 14 onces (no mag)
With qd bipod and and inforce 500 lumen/IR light : 9 pound 1 onces (no mag)
All that thanks to the mft stock, aero precision ultralight and the 14.6 oz leupold scope
Now what I noticed, I had to give a quarter plus turn on both the screws that hold the were pad for the charging handle as they were pertruding and the handle was rubbing of the finish. NOT a big deal don't care it took 2 second to fix. There seem to be a minimal up and down play in the rear trunnion that engage the lower and upper, its not a big deal since it doesn't affect accuracy and I will easily take care of that. Lastly looking down the bore at about 10 o'clock there is almost no clearance between the gas block and rail and very little force is needed for the gas block to make contact with the rail here and there is faire amout of clearance at 2 o'clock and up and down. Now for that it could be an accuracy killer imo? But I will wait for eather atrs to chime in or I will give them a call in the next couple of days. So I am not shipping it back for that as I am in N-B , I expect that after first consulting with atrs I will be taking a dremel to the inside of the rail to give me extra clearence.
Part from the last issue I am 100% happy with this and with the clearance issue I am still at 97%
I love the versatility of the package as I am able to swich my 2 bipod ( cheap cadwell on mft qd mount {pictured } and Sierra S7) between my DD M4V5, MV, BF M14 and lss-xl 10tr and my inforce light between the DD and MV. Also with front and rear handguard qd cup, magpul asap qd cup and the mft minimalist stock bottom qd cup its going to be great with my magpul ms4 sling switching from single to double point sling.
I borrowed the leupold from my RFB and I will need in the neer future decide what scope I put on this.its going to be a battle of price vs weigh vs capability/versatility. I am looking at the leupold vx6 hd 1-6, burris xtr ii 1-8, trijicon accupoint 1-6 and trijicon accuepower 1-8 ; maybe even the primary arms 1-8. Decision decisions. Also I will be ditching the A2 bird cage soon.
I'd go with the Leupold VX6 HD 1 to 6 or 2 to 12. Must admit - no first-hand experience with any of the others, but have a VX6 3 to 18 I'm super happy with on a 7mm. Already had an optic to put on my MV or that's what I would have gone with. 16oz and tremendously useful magnification range... good for 3 gun to gophers to coyotes with that...

The KAC URX is on da way..
Hope I didn't make a mistake
I got my MV and having sum problems with the fit of the upper and lower so it's back to ATRS
Never put a roand throw it as problem is I can see day light all along the seem between the upper and lower and Ther is play between them

I do think minimal play between the upper and lower is normal due to the trunnion system, cause remember this is not an AR , I imagine that if the trunnion was machine the exact same size as the protrusion in the upper it might be extremely difficult to asseble together.
Maybe others can chime in and give there opinions on this mather.

The trunnion is supposed to be a little hard to get together/apart, and is supposed to be a much tighter fit than the average AR. My MV has no gap between upper/lower and has very very little play.
I can see daylight between the upper and lower except were the retaining pin is on the receiver and the back pin so just getting a poor 3 pont contact

How's the reliability on these guys?

Don't forget the sightron 1-7, I've been tempted by this model for quite some time.
I bin so busy I still haven't sent my MV back to ATRS at this point I would say the MV sucks but I will see how ATRS deal with the poor fit between upper and lower
