What's up yall,

So I finally got my optic (Vortex Viper PST 4-16) and a Larue LT-135 (1.93" from Center-Line) in for my Sig716 (16" Patrol in OD).

I am going to get a local shop to do the mount, but when I mocked up the setup at home, I'm wondering if I should do another mount (I'm keeping the optic - I like it too much).

I want to use my 716 for deer hunting, maybe out to 300 yards, 400 max. I'm in MD so those LOOOOONG shots aren't too easy to come by.

Problem I'm having is with eye relief. I bought the Larue LT-135 mount so I could keep the optic above my iron sights (I'd like to keep them as a backup).

The furthest I can get the scope back still requires me to put my cheek almost all the way to the front-end of the stock plastic to get proper eye relief. The only other option I can think of is to adjust the stock in a few clicks, but I'd rather keep it fully extended for shooting comfort.

Any suggestions on what I could do? I'm wondering if there is another high-mount QR one-piece mount that will get the scope back but also maintain the height I need to keep the scope above the iron sights. That LT-135 puts the optic awfully forward. As far as mounts go, I want a one piece QR and high quality. A local gun shop recommended the Burris PEPR but I'd be really pushing it with clearances since it's 1.5" from center. With the optic and the quick-throw magnification lever on the scope (you can see it in the pics) I think I need to be in the 1.7" or higher range.

Pics to come shortly.

Thanks in advance for suggestions.

Nice set up, it looks like you have plenty of room on the back side of the rifle above the rear sight but the clearence is a lot less near the objective lense. I think the Burris PEPR would still work for you but it looks to me like the PEPR pushes the scope forward when it sounds like you want to bring the scope rearward. Not sure if you can reverse the PEPR so it cantilevers the scope more to the rear, but there are other options.

Here is a quick google on it

how to cantilever a rifle scope - Google Search

the NcStar 74220 AR15 QR Weaver Mount Cantilever rr 30mm is the only one i saw with QR not sure on the clearances.

I spoke with LaRue today and they unfortunately don't have a mount that will get the scope rear-wards. They did say it was ok to mount the LaRue backwards, so I'm going to give that a shot (and see if I like the way it looks).

I would suggest angled mounts (Daniel Defense or Gear Sector) for your iron sights and mount them to the right of your scope.

Man! I am looking at using a Viper PST 1-4x24 for my Sig 716. If the the eye relief is 4" thats a plus. So your mount places the scope high enough to eave the rear BUIS on. What mount is that? I live on MDES near Ocean City BTW. Thanks.

I am running the LaRue LT-104 (zero MOA) with my Vortex Viper PST 2.5-10. Works very well. I have no intention of reaching out beyond 600 meters so I did not see the need to add any MOA to the mount.

Another mount to consider is the American Defense Recon mount (1" or 30mm). There is another one that pushes the scope further forward, and one with 20moa built into it.

I have a HiLux CMR 1-4x24mm on my Sig 516 (had a Burris P.E.P.R. with a HiLux CMR on my 716 that I sold) and its mounted in the Recon mount with 20 MOA. Quick release, so you can pull it off real fast and use irons if you wanted to do so.

I just pulled the CMR out and put a Leupold Mark IV Precision 4.5-14x40mm on the 516 to see what kind of accuracy its really capable of (Timney 3# trigger, KNS Gen II trigger pins, BCM Gunfighter large charging handle, Vtac padded sling).


I think the American Defense mount is slightly cheaper than the LaRue as well.

OP:
Nice scope and mount!
I've got Nikon M308 w/BDC. IMHO...one of the reasons I've bought the Nikon M308 is because it comes with an awesome mount.
Cheers!

Vader - it's a Larue LT-193 mount - gives plenty of room above the BUIS including a little room for a Vortex quickthrow lever...

If you are having any issues with a Sig 716 that is new, before you use it clean it thoroughly, this is absolutely essential as they come from the factory with a heavy grease/cosmoline type of protectant throughout any of the moving parts. I have read several articles and this is the advice of experienced Sig owners, I will tell you it is a must, once you start cleaning you will see what I mean, after cleaning they cycle like a dream.

Why are you giving gun cleaning advice in a 7 month old thread about Scope Mounts? Just curious :lol: .

Your first post to boot.
