I have a CMMG Quebec-A (dedicated .22lr upper on a multi-caliber marked lower) and I want to mount a red dot on it. The red dot I have is a Millett RD00006. I have A2 style sites (cheap UTG) and a riser for the red dot so that I can set it up to co-witness. Problem is that the riser rail is longer than the the rail that is left on my receiver. Could I mount the red dot at an angle? Are there drawbacks?

Please don't respond with get a primary arms, eotech, insert brand x here. I have the equipment that I have and it is a .22lr plinking toy. Once I get a 5.56 upper, then I will come back for suggestions for both BUIS and optics.

Thanks! :wavey:

Are you saying the riser is so long that it won’t seat properly on the upper? If so, can you cut off a section of the riser or just get a shorter riser?

Post a photo.

Is your rear sight set to the rear of the rifle's rail? If so, I can't picture an optic riser that wouldn't fit.

This is my N4 with a typical mounting system. Note the position of the BUIS and where the riser/optic is located. Is your setup similar to this?

I have partially solved the issue. I didn't realize that there was a "front" and "back" to the riser. The screw on the front is flat on the part that runs through the riser, so it can rest on the receiver without going through one of the grooves. It is mounted, but isn't very appealing. You can see in the photo how the riser hangs off the end of the receiver and over the ring on the handguard. I tried shifting it back a notch, but with the site, it won't match up with the grooves in the rail.

OK. Most of the RDS have unlimited viewing distance, so you can move the sight a little more rearword. Also, try a different BUIS like the fixed models from DD and Troy.

Can you just lose the rear sight?

I thought about that, but I don't know how long the battery will last on the Millet red dot. I am setting up my son's S&W M&P15-22 with magpul BUIS and a Bushnell TRS-25. His will be done right and look like TedG's....

Do you mean move the red dot back on the riser, or move the riser back?

What would it matter? You have spares, right? Just ditch the rear sight, end of problem.

This was what I was thinking as well. Lose the rear sight, carry extra batteries, and you're done. You said this is just a plinking gun right?

True, it is just a plinking gun. Nothing is on the line and depending on me and my .22lr. :supergrin: I was hoping to be able to set it up so that I could use the sights as well, and I wanted to set it up like the big kids, but with the equipment I have and the limitations I have set, maybe that isn't possible.

It is useable the way it is now, I just don't like how it looks.

This is what happened...I bought the rifle and it was a flat top, no sights. So, I went to cheaper than dirt and bought the A2 style sights...cheap, and in stock. Thought the rifle was fine and I was done. Then I saw this red dot on sale at Academy, and I am a sucker for a sale. Didn't need it, but thought it would be fun. So here I am trying to now make my .22 tacticool, even though I said I wasn't going to when I got it.

It's called AR Creeping Disease, it's a slow drain on your fiscal holdings and mental stability.:rofl::rofl:

It is, but I want to creep to a new upper (or a whole rifle, but don't tell my wife) so I shouldn't be spending my money on silly crap for the .22! :cool: Plus, my son is twelve and has COD disease, and wants his rifle to be totally tacticool. Drives me nuts, but keeps him interested in shooting, so worth every penny.

I completely understand, I have COD disease myself, it's a *****.

I even painted my AR to match the M4 in CODMW2 like a putz.

Jeeze, I'm 42 and still acting like a kid........




















SWEEEEET!!!:rofl:

I'd move both.

The riser can't move back, the back screw won't go into the groove on the receiver rail. The sight keeps the riser just far forward that it doesn't line up.

Perhaps there is a different mount I could use, instead of using the riser and the rings.

You can buy rings that will mount the scope higher and might be able to do away with the "riser". Like these....

ARitis is very addicting.....:rofl:

In regards to the riser, if it just a plinker and is sturdy who cares what it looks like.

I guess I do. The twelve year old can't know that his rifle is set up better than his old man's just by looking at it. :embarassed: Although, since his handguard has quad rails, he already thinks his is better.

these are both excellent suggestions. Either one of them would solve your problem and the price is right.

I would hit the back of the riser with a grinder until I could move the riser back. then I would hit the front with a grinder until it was flush with the front of the receiver. A little flat black paint and it would look like it came that way.

I just received my new SPARC and mounted it in the normal configuration.... DD1.5 co-witnessing at lower third.
