I did that on my Block 1ish clone when I put it together. Keeps the left side of the gun "cleaner."

Anyone else have an issue with the Ergo rail canting downward when tightened? Mine is touching the barrel at 12 o'clock on the inside of the rail.

Yes.

I put the upper in a vice block, in the vice. Then used a rubber mallet to “persuade” the rail to center.

Was very simple and it has stayed very much centered since.

If you wanted you could place the magpul afg across it and the ras to keep it level then tighten. Otherwise I would think of some rigged spacer to help even it out.

To me is doesn’t look like you could bridge the gap, if you look at all the pics the rail is not the same size as the kac rail.

If you take a look at this pic, it looks like the BCM vert grip spans both rails. It's worth the try with the afg or kac rail.

I can get down with that. Been torn on the ergo, I have an OG YHM tri rail that does what I need but man these just look so much better.

I can see in his pic it doesnt line up. I'm saying if you look in both the pics I posted the vert grip is holding both the ras and the ergo. The vert grip is engaged by the pin in the center. It is partially on the ras and not fully engaged.

You’re right, it certainly does appear as if the verticle foregrip is spanning both rails. If it can be made to work that way, then I think that is great. I’m just not seeing how it’s possible.

Here’s mine for example: (as you can see in my previous post the Ergo Rail is pretty damn centered too)

That's why the AFG looks better because you can mount it far enough back on the Ergo that it butts up against the KAC rail and hides this gap. I think it looks kind of weird in the pictures that show the vertical grip mounted half off the rear of the Ergo.

[Last Edit: usmc_noma] [#29]
My personal preference is to not have it span both rails unless it had significant coverage such as an afg, but if it works how you want it then go for it.

If you look at this pic, the ergo is definitely canted and does not line up with the ras. You can also tell the barrel is higher as well which would match up to the upper portion being close to the top rail closer to the muzzle.

[Last Edit: prskiller] [#30]
Sort of done for now, will later add an EXPS3-0. There is no bridging the gap. The ERGO is considerably smaller all the way around than any quad rail out there.  The BCM grip will not go to the rear of ERGO due to the sight base bayonet lug. Mines is front of kac rail with a little portion of it hanging but still solid.  Could not at all secure forward rail without it canting down but clone so who cares.

Hey Folks, don't have an exact clone but more so inspired by (BCM 14.5 not clone correct but similar enough). My ergo rail cants down a little bit, but doesn't touch the barrel. Not the worst thing in the world. However, when mounting a sling, should I put the sling mount on the RAS or would it be OK on the ERGO? I like to have some tension on my sling when I shorten it (BFG Vickers). I know the rail isn't FF, does anyone know if it would have a POI shift if it was on the ergo rail?

Also I'm seeing some streamlight tlr1's in pictures. A couple other photo's look like protac's. Unless my eyes are deceiving me and it's a surefire.

Magwell gripping Marines probably wear white socks too . Don't worry, I won't tell.

Thank you.

I was in the same boat. The mallet method, as described above, worked for me. YMMV.

What exactly did you wack on with the mallet?

The more I observe the setup I begin to notice that I believe the discrepancy lies with the top mounting bracket and it’s relationship with the front sight base.  Before I tighten the screws down the rail is aligned.  But once I begin the final tighten process I can see the rail move up to conform with the top mounting bracket.  I wonder if some shims would do.

Can't find the picture.   But kind of by accident, I discovered when I slid on my Spike's Havoc 12", on my LE6920, it fit over both the KAC rail and the Ergo section of the rail.  Had to do so before I completely tightened the Ergo down.  Once I did, it straightened out the downward cant, and the Ergo and Havoc kind of locked each other into place.

Thank goodness.

That 1152 round is pretty hot. Like 1300 FPS from the sig.

Only makes sense since the USMC was going Hks all around they would adopt some kind of shorty 416 for the go fast dudes.

Giessele doesn't make a riser. And probably got the Geissele first and then decided that he needed it to clear the laser and bought the Larue, because he also probably didn't want to re-center the optic by having to buy a higher mount for it.

He would have been better served by getting a Badger in the correct height of 170 or 1.93 to clear the laser, and saved money and still have a better mount that's modular than both companies currently have to offer.

It's just a cheap beater rifle I had laying around (RRA lower with a PSA 14.7 upper), but the only thing wrong with that rail is it weighs just under 50lbs. Holy fuck is it unnecessarily heavy.
