Rifle Scopes Scope Mount - DPMS .260 Remington w/ Sightron SIII

[jagsr71]

Hey guys. I have been lurking here reading up a lot of stuff for the last few months. I really enjoy this site. I just have a quick question for all of you that have done this waaay more than I have.
A little about me since this is my first post. I grew up in South Dakota where I have been used to shooting mostly bolt action rifles (primarily in .223, .243, .308, 30-06 and 300 WM). Within the last few years, I have really enjoyed owning a couple of AR’s especially for their accuracy and follow-up shots on varmints (primarily coyotes since I live on a ranch with LOTS and LOTS of land around me).
I have just purchased a DPMS chambered in a .260 Remington and it’s just an absolutely beautifully made rifle. I am absolutely in love with this caliber. I can’t believe it’s NOT more popular! I purchased the hunters version that has been shaved down to 7.9 lbs and I really want to be sure to set it up with an excellent scope mount.
I have purchased a Sightron SIII SS 6-24X50 LRMOA scope for her. Here is where I REALLY need some input. I have another AR platform (in the ubiquitous .223) that has a complete Larue LT-104 mount and the height is just fine for me (very solid). However…. This .260 is a completely different animal that will be quite capable of going 1000+ yards. I was looking at the Larue LT-158 for it’s capability of 10 MOA down angle. However, Badger makes a 22 MOA canted riser that really sounds good (since it would give me even more down angle). Should I go with the Badger and a low set of rings? Will this give me the proper height for this AR platform? As for the charging handle, I’m going to order a DPMS "Tactical Latch. THE BOTTOM LINE - I don’t care if I spend a bit more money for the scope mounting as long as I have the right set up for proper long range shooting.
Thanks!

Badger 22 MOA riser and medium high rings would be about right, maybe standard if you don't go with the 20 MOA one piece mount.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

that scope advertises 100MOA of internal adjustment. if that is true why do you think you'll need a canted base?

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

BCP - Exactly and thank you! It's a brand new scope/rifle to me. That's why I'd like to get some knowledgeable feedback from some of you that have a similar set up.
Am I just being extra overcautious for no reason or should I forget about the Badger 22 MOA riser and just get some Warne Maxima AR steel QD rings and call it a day? If so, then what height rings for a perfect alignment with a proper cheek weld? Standard like FCS suggests?
Any other mounts suggested for this AR10 style rifle that would be an optimal set up w/ this scope?

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

The Larue is a good mount and the correct height, and a SIII 6-24 has 100 MOA travel which should easily get a .260 to 1000 without a canted base. The LT58 does not have the cantilevered base which is important for an AR to get the correct eye relief. The Badger rail/rings will also have only limited cantilever effect - not nearly as much as a Larue.

You don't need a canted base, you only need enough travel to get to 1000 with a .260. Maybe 35 MOA tops from a 100 yard zero?? The SIII 6-24 will do that and have room to spare with a flat base.

Take a look at the Nightforce Unimount. I don't have any experience with it, but I am thinking about one for my AR10. LaRue and ADM also make mounts with 20 MOA built in, but if you don't need the QD feature, why pay for it?

As to why on the 20 MOA. Scopes tent to have more distortion closer to the edges. It is better to have the erector as close to center as possible.

I used one of leupold's new ar mounts on my AR varmint model with the SIII 6-24x50 scope. Worked great.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

If you already have a good setup, USO makes a 22MOA rail you could attach to your existing mount and just move your rings onto. If it works, you could bed it. Just another option.

+1 The LT158 is the ticket. Plus, it has 10 MOA built in.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Thank you for all your input. I think I'm more in the camp (where I'm leaning towards the LT-158) due to what a few of you have mentioned:
1. It will be the right height (1.44" above the rail).
2. At least it gives me an extra bit of 10 MOA of down angle (just in case).
3. It's cantilevered forward (like the LT104) in order to get proper eye relief.
4. It's one piece and NOT three separate items, w/ less chance of things going wrong.
If I get it, I think I'll opt for the VFZ mount instead of the levers for a more permanent install.
I was checking out TYB422's pic of his premier scope mounted on the LT-158 and I gotta say... Looks pretty damn good!

Am I just convincing myself or should I seriously be considering any other options?

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

I use the Badger 22moa rail myself. If I know I was going to keep it on the rifle I would just do a 1 piece mount but I move my scopes off AR15s and AR10s to my bolt rifles. By using the Badger 22moa mount and 0.885” center height rings I can mount my scopes to any rifle.

Here is my DPMS LR-308

I run a Sulphr they are awesome.

AADMOUNTS will be getting my money soon.

Both are cantilevered and have 20MOA built in.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Mike - That DPMS LR-308 is beautiful and you just gave me the answer I was looking for in the height of the rings if I were to go with the Badger riser. I do like the idea of a one piece also.
Inline 6 - Thank you! I checked out AADMOUNT: http://www.aadmount.com/
Needless to say, I was THOROUGHLY impressed! It is certainly overbuilt and engineered! Once mounted, I doubt it's going ANYWHERE! I may be completely wrong but it also seems like it wouldn't scar up the top rail. I think the LT-104 I have does that a bit to my other AR (or is that just me?).

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Regardless of mount manufacturer I would have a look on the heights as there is a big differance betwen them and the cheekweld is important.

I would also consider QD or not.
If there is a use for QD and I had more than one scope I really wanted to use on the gun I would consider QD, if there is no use for QD and the accuracy is first priority I would go for a fixed mount.

Agree completely. Unless you think you'll need to quickly remove the scope for use of BUIS or will frequently move the optic between multiple rifles, QD mounts are not necessary. Cantilever designs are usually needed for AR-15 but not for AR-10 platforms. Lastly, with a 260R and the scope you mention, forward MOA tilt isn't necessary either.

I'd mount it with a good quality set of high rings directly to the pic rail of your rifle and be done with it.

This I DID NOT know. I realize the AR-10 system is beefier but it seems like the scope mount system would be the same on a flat top. Why is it different?

High or X-High? I keep hearing both options. Probably because each company has a different definition. Definitely something I considered which has me thinking about it again (especially if cantilevering the scope forward is not necessary in an AR-10).

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Look at the pic that Mike @ CST posted. I have to use a cantilever on mine. I will say the scope will have a lot to do with that.

This is the same setup I used on my LR-308 and it worked great. Seekins rings are great.
If you have to have a QD go with BOBRO, GDI or ADM.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Anyone had any experience with this Larue mount?

http://www.laruetactical.com/larue-tactical-20-moa-psr-scope-mount-qd

I'm leaning towards the AADMOUNT or possibly this one. I really don't think I'll need a cantilever option (since my scope seems to do a good job of providing plenty).
I know my scope provides plenty of MOA adjustment but... It doesn't hurt to get a little bit extra.
AADMOUNT seems rather hefty in weight though.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

I know that LaRue isn't very popular around here but I don't think you can go wrong with any of their stuff. I don't have experience with AR10's but would think that the LT-158 would be the safer choice. If you don't need the cantilever just move it back some. Looking at the pic that Mike posted, I would think you might want a little but again don't have first hand knowledge.

I think you will be very pleased with the Sightron. I really like my LRMD and just received my LRMOA yesterday.

 

[jagsr71]

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Good to hear on the scope choice. It has excellent glass clarity.
Thanks for the advice on the LT-158. It's a pretty good choice. I keep researching (time given)some of the other choices folks have been mentioning.
The NF Unimount and the AADMOUNT seem like a great way to go. I love the Spuhr also but... It's some serious money!
The Bobro, ADM,and GG&G are great too but they are lever QD and I'd rather have something more permanent.
The NF Unimount,AADMOUNT and LaRue also have MOA built in and it's just something I like.
One of these three is going to get my money. Probably the one that weighs the least.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

Hey Jagsr71, Ive been here doing some research and I just picked up a DPMS .308L, Im still researching a scope for it and I was wondering what mounts you went with, and if you ended up getting the DPMS "tactical latch" and if you like it?
Thanks for your time and help.

Also, I would have created my own post on this topic however Ive been on this forum for about 10 min and still cant find how to create one.

Re: Scope Mount - DPMS .260 Remington w/ Sightron SIII

For what it's worth, I have the same SIII as you and have a 0 MOA mount on my 700 and I can't quite make 1000. I am about 4 MOA short.
