Had Noveske NSR rail professionally installed.  When I attempted to put a Magpul front sight on the top rail, it wouldn't slide on.  I finally tapped it into place with a HAMMER.  That concerned me but I figured that possibly the Magpul was too tight.  Then I tried to slide a Troy sight onto the rail.  No go.  I took a Troy rear sight apart and put it on the rail and it tightened to the point only where there is an unsightly gap.  At this point, I'm thinking the sight has to be off center.  Next, out came the calipers.  The Noveske top rail is significantly wider by scale than my Colt and Daniel Defense rails.

Anyone else had this experience.  It is unusable as is.

I mounted a Bobro cantilever Aimpoint Pro mount to my NSR rail to "rough in"/boresight my Vortex 2.5-10x.
The Bobro mount was difficult to lock in.  It closed after much fudging-with-it.  The NSR rail is "different" than my other Centurion CMR or C4 cutout.

If the rail measures too wide, it much be machined a little off.

I would contact Noveske and see what They can do for You.

Since it is not a complete upper from Them, I would bet You are going to pay to remove the rail and replace it with another one which sucks.

Yeah, but Noveske may step up and allow him to ship his entire upper over to them. They may do the swap for him in house.

OP, I'd definitely reach out to Noveske regardless. The rail shouldn't be wider than any other standard picatinny rail.

He should be able to remove the rail itself with the appropriate screwdriver. The barrel nut doesn't need to come off. When I put a surefire x300u on mine I had to use a rubber mallet.

All of the newer Troy sights have that gap. it's "supposed" to be there, according to them.

I have a T1 with a Larue LT724 mount that went on just fine. I'm kind of curious now. I might try putting on an BUIS I have laying around to see if I get the same issue.

I don't have a newer Troy sight.  My rail is wider than any other rail I have in the house per my calipers and the inability to get any accessory on it.  If you saw the gap in the "older" Troy sight on this rail, you wouldn't like it.  Barely enough metal to get the screw into place.

Bought and installed by Noveske dealer.  I was hoping for a more useful answer.

Email Noveske take off the (6) NSR screws with the supplied wrench send them the rail swap it out for more useable one re-install on your barrel nut....nothing to it.
(may have to apply heat to soften the locktite)

Every magpul sight I've ever put on was tight.

I have 4 NSR rails, and I've never had an issue putting sights on them.

The Troy sight is shit.  My magpul sight was tough to get on my noveske rail also.  

I had the EXACT same experience.  Once I ditched the Troy everything was fine.

The rail is wider than it's out of spec.

Thanks for all the replies.  Maybe it is a Troy problem.  However, the Noveske rail that is mounted on the side of the assembly, for the light, etc. is significantly narrower when measured with calipers.  The Troy and Magpul stuff slides right on that one.  I'm assuming both are made by Noveske.  I'm going to try and put a friend's Yankee Hill front sight on the rail tonite.  I will report back.  

The NSR is mounted on a Colt upper.  The rail on the Colt is significantly narrower than the Noveske when measured with calipers.  You can actually see the difference when eyeballing it.

Well, it looks like the upper is going to Noveske.  BTW, all of my rails measure .835 with calipers obviously, Colt, DD, etc.  This Noveske measures .839.  The spec for the Picatinny rail is .835.  The Noveske is clearly out of spec.

Rail at Noveske.  Great folks to deal with so far.  They have encountered this problem.  I will let everyone know how it turns out.

While it is great that they are helping you out and blah blah blah, I don't understand how this shit happens in the first place.  It shouldn't be the customers place to check for out of spec parts but that seems to be the case with everyone.
