Im not TR, but here is my M4 with a KAC Cantlever mount. Yes the mount is "Backwards" but I like it that way.

Thank you Psywar.

I unfortunately do not have a RAS or RIS so that config would not work for me.

However, how do you like the cantilever?

I'm not for sure however here are the specs...

One of my Aimpoint set-ups.

IIRC, this one has a full spacer.

This is an MSTN built rifle with the cantilevered mount (oriented correctly), among other goodies.

Do you perfer the Arms #22 over the cantilever?

Beatiful hardware. Thank you for posting the photos.

I do.

It is a quick release, while being accurate and repeatable enough for the optic.

Of course, if you want yours mounted forward directly over the delta ring, you have to go with the cantilevered mount.

TR

I have not messed around with either the cantilever or the Arms #22 so I don't know which one I would perfer. It just seems that the farther forward on the rifle the sight is the quicker it would be to acquire.

Is that right? Or at a certain pont is the sight not very easy to acquire?

Also with the spacer are the BUIS still co-witnessed?

ARMS now makes a cantilevered full spacer for the #22 that looks like it is built the same way as the normal spacer (robust) but will allow you to move the optic over the delta ring. I think MSTN has them.



Take care...

Has anyone used one of these?

Any thoughts pros or cons you can come up with?

Joe,

I really prefer the Cantlever. I had an ARMS mount that I used on the RASII hump, but it kept comming loose. I have alot of customer loyalty to KAC, and the short time I used the ARMS mount made me feel dirty LOL.

You said you dont have a rail system, I would seriously consider picking one up. The RIS or RAS and get the SAS Bottom Rail upgrade. That way you can mount the scope as far forward as possible. Used systems show up over on the Equipment exchange on AR15.com on a regular basis.

Thanks Luke but I just shot my savings on the sight and mount so it will be a couple more months until I can pick up a SIR, RAS, or RIS. I really want a rail system I just can't afford it right now.
I will start checking over on AR-15.com thanks again for the tip.

What is with the SAS bottom rail upgrade I don't think I have ever seen/ heard of one.

not really needed unless you plan on doing muzzle strikes - so the bottom half of the RIS won't pop off during one.
cheers,
MM

Update
 

Wooooo hooooo,

I got the Aimpoint Comp M2 w/ pri mount in today. I will post photos later.

THANK YOU WES.

Re: Update
 

Same place I got mine.

Wes is good people, the optic is a good piece of gear.

He is a wealth of knowledge about what works as well.
