Hi guys! I have been reading through these forums and have saw a lot of posts on aimpoint mounts. To me a beginner to the world of Reflex sights though, it means very little. So if someone could please take the time to help me i'd greatly appreciate it. Below i'll put a list of the questions that I have and maybe you could take them one at a time? Please keep in mind that my knowledge is limited so speak in Layman's terms.

First off though here are the specs.

- Aimpoint Comp ML2 to be mounted on Bushmaster flat top reciever M4. Weapon also has an M-33 dual rail forearm.

- Have Bushmaster B.M.A.S. back up iron sights

Now here are my questions:

1.) What mounts do you guys reccomend that I use and where can I get them? Please be specific and detailed. Keep in mind I will have back up ion sights.

2.) Where on the rifle should I mount the sight? Where is the best place to mount it and how far from my eye?

3.) Can I use standard 30mm Millet rings to mount my Aimpoint and if so can I still use my back-up iron sights? Can I use a spacer and a 30mm ring to mount my sight?

4.) How do you use the back-up iron sights in conjunction with the Aimpoint sight?

5.) The guys at SWFA reccomended the quick release mount which they sell for like 81 dollars and a 9 dollar spacer for the back-up sights. Is there anything wrong with these mounts? Is there any cheaper option?

Once again please thouroughly answer these questions. As much help as you guys can give me will be greatly appreciate. Thanks so much!

Here's what I use, I'll answer your questions below.



1.) My prefered mount is the #22M68 w/ cantilever spacer from A.R.M.S.- www.armsmounts.com/catalog.php?action=124&item_id=26, and www.armsmounts.com/catalog.php?action=124&item_id=23

2.) The best position for it is really personal preference. I prefer my optic as close to my eye as possible. Others prefer it as far away as possible. It's really how you train and how you feel most comfortable.

3.) I don't believe so, but I cannot say for certain.

4.) I use an A.R.M.S. #40L as a BUIS. If my main optic fails, I can immediatly flip up the rear sight and continue shooting without doing anything to the Aimpoint. If I get to a place where I can take off the Aimpoint, no problem with that either (with the throw-levers).

5.) Specifically which mount is this manufactured by? I don't know enough from the question to give you a good answer.

Hope that helps some.

I just purchased the Aimpoint/LaRue mount package from Grant. I love the LaRue mount and so will you. Works perfect, and they give you a armadillo shaped bottle opener too...LOL..Can't beat that!!

I have a question. How much pressure do you apply to the ring when mounting?? There is a small gap at the top between the rings. Should there be?? Or should the top of the 2 ring halves be closed??
Link Posted: 8/7/2004 8:31:05 AM EST
Cool! This does help a lot. I think the A.R.M.S stuff that "UHLEK" is suggesting is the route that I will go. I do have one more question though. Do I need to buy a spacer for my back-up iron sights with this A.R.M.S mount or does it come with them? Or do I even need a space with this? At least until I do more reading about em I don't care much for that extension though. There is something about the sight sticking up that high that kind of worries me about tendencies to get snagged and such.


As for the QR mounts I was reading yesterday where guys were having trouble with them working loose so I think i've ruled those out.

BTW how much does Grant sell his LaRue mounts for just out of curiosity? Does anyone have his website address again? I've lost it

Specter1975: I have a Bushy M-4(a)(3) set up with the LaRue M68 mount and a BMAS flip-up BUIS. The irons co-witness in the lower 1/3 of the Aimpoint tube with no spacers on the mount or BUIS. I like it that way. I got my LaRue from Grant and I can tell you I was impressed with his service. LUMPY or GRANT: What about Cheaptrick's question? I am also new to the LaRue and have a very small gap at the top. This hasn't been an issue so far. Will it be?

Yep like Grubbs said. If you completely close the top, the bottom will be loose and rattle. So eliminate the gap on the bottom first, then deal with the top.
No need to ask me how I know

Roger that, I thought so but wasnt sure.
No reference to inch pounds on the instructions. I didnt want to overtighten the screws.

Ok guys now I do have one more question hehe.

I'm sorry if I sound dumb but like I say I am new to the world of reflex sights and modular weapons. I have owned plain Jane, Colt and Armalite AR-15's since I was like 15 years old. Even have a registered full auto M16A2 but this is the first project of the sort that I have undertaken. See i'm slow to catch onto the latest technology. I guess my father taught me to have a bit of an old fashioned streak. Anyways here is my question:

I take it from reading your posts that in order to use my back-up iron sights, I look through the Aimpoint scope right? I don't look over it or under it but rather through it? So then I assume that the spacer fits underneath the iron sights in order to bring them up high enough to line up with the bottom 1/3 of the reflex sight recticle? If this is correct then please let me know. Also does everyone co-witness their back-up iron sights with the Reflex sight or is there other options?

Once again sorry for the ignorant newbie questions but I am a learner.

#1) Thanks, McGrubbs!

#2) Specter: Yes, to "co-witness" you look through the Aimpoint (or other CQB sight). Many people have different ideas as to what "co-witness" means. To many, it means that when you flip up your rear sight and look through the Aimpoint, the red dot sits on top of your front iron sight post and is perfectly centered within the rear sight and the Aimpoint tube itself. I do not do it this way. "BUIS" means Back Up Iron Sight. To me, that means just what it is, A BACK UP. I never have the red dot "on," and the BUIS flipped up at the same time. The BUIS is only there if your red dot ever fails. (IMHO) That's why I like the LaRue mount. The irons show up in the lower 1/3 of the tube. This means that when I have the rear BUIS folded down, the dot is ABOVE the front post and the rear sight is out of the way. (Very clean, uncluttered view.) There is more than one way to skin this cat... just the way I do it.

... and if you have a fixed (Larue) BUIS, it will also be in the lower 1/3 and won't even be noticed until you want to check zero, and then the dot will be right on the post as well (as long as you have both zeroed the same). For me, I always have the dot and the BUIS in operation simultaneously. YMMV

Hi all,

Since this thread is still alive, I had a similair sort of question...right now I have a plain Bushy superlite with stubby stock and fixed loop carry handle (is that the right terminology? forgive my ignorance). I'm in the process of upgrading it (most of the fun upgrades won't happen until the hateful ban <spit> ceases to exist) and I've decided that I would like to get an Aimpoint. Also, because I have no doubt that the Socialist Swine will be bringing the AWB back ASAP but this time it'll have teeth, I've also decided to get a Bushy M4 (flattop) with as many evil features as I can stick on it + some other shit I've been saving up for since 2001...so anyway here's my question:

2 rifles: one with the "loop" with the ARMS gooseneck or the litle mount that screws to the loop...and the other a flattop with either the Larue mount/BUIS or the ARMS M68/#40L. If I get the gooseneck, which Aimpoint mount should I get so that the irons are in the bottom 1/4 or so? I want the red dot to stand by itself and have the front post low in the sight. Do I need to get spacers in order to do this on the flattop, also? Do the spacers make the mount less secure?

Looking to build 2 uppers next month.
One being an M4 A3 with Aimpoint and need some mounting and BUIS info.

MPW, just get a flat top, your options will open up a lot more in terms of optics. Fixed or removable carry handle suck, it's neither here nor there, many people chop it up so they have a rear sight but also have room for optics ahead of it.

As to the A2 upper you already have, get an A3 flat top receiver. I have a Colt A2 and a Colt A1 receiver gathering dust, I will never go back to either.
Link Posted: 8/8/2004 6:57:32 AM EST
Duffy,

Good point...and if I bought an A3 upper, when it goes to the smith...he could also add a FS to the other end...

The thing is, I really shoot well with the irons on the "loop"...I hate to screw with a gun that really shoots well (for me). My nose just barely touches the charging handle, and I can snap the rifle to my shoulder and get an excellent sight picture. If it's not broke....
Link Posted: 8/8/2004 7:11:53 AM EST
My BUIS also show up in the bottom third of the Aimpoint. I use a 22M68 without any spacer at all, on top of an ARMS SIR, with an ARMS #40. Flipped up, the sight co-witnesses almost touching the bottom of the Aimpoint "tube".

Were my Aimpoint mounted directly on the upper reciever, the sights would be closer to the middle of the tube. SIRs add some height to whatever scope you hang on it, unless you mount it forward of the "hump", which I didn't.

What's that, you ask?

Yes, this squid finally got his rifle put together. :)

I will post pics when I can....

Honestly, I think you are hanging on to a non-issue. Just get an A3 upper. You will find that you will shoot as good or better with a flattop gun.

YMMV

Yep what Grubbs said there. If you really like the A2 sight's form factor, sight picture, etc., it can be easily duplicatd with an LMT or LaRue BUIS, while using either of these, or any of the other BUIS out there (KAC 300/600M, any of the ARMS #40 variants, GG&G MAD, Troy Industry's Battle sight), in the mean time they all will leave you plenty of room for low mounting, closer to bore optics.

Unless you really like the "tunnel" of the fixed or removable carry handle, I'd switch to a rear sight that takes up one rail on the receiver.

...just to clarify, the LaRue mount is the same height as the taller PRI mount....correct? Also, will the LaRue mount fit with an LMT BUIS (I know a PRI one will). Anyone have pics with an LMT BUIS and a LaRue-mounted M2? I have seen some very nice pics of LMT BUIS + PRI mounted M2s... :)

Thanks.

Ahhh.... Thanks Lumpy! Actually it was the old picture of your rifle with the PRI mount that first convinced me to lean towards it (at least I think it was yours).

Lumpy an company,
Here's another question fer ya'. I'm getting a RAS II and LMT BUIS. I was going to get a ARMS #22M68, but have since been thinking of the LaRue. What is there "equivalent" to the ARMS that will mount on the "Hump" and let me cowitness with the LMT BUIS?

Thanks

I have 2 Colt's with RASII and have replaced an ARMs & GG&G mount for the LaRue low mount. You will like it.
Link Posted: 8/28/2004 1:32:51 PM EST
Also,
Other than obviously being shorter than the "regular" M68 mount, is the short one just as high quality? It looks significantly less "beefy".

MMMMMMMMMM Beeeeef.

You don't feel like the single point lets the muzzle swing too much?
