Mounting a Nightforce F1 3.5-15 on an AR-10T

[Maestro Pistolero]

I am using the supplied Ultralight rings.

Can anyone point me to an FAQ, thread and/or video, or any information on how to do this right the first time?

Thanks in advance.

Same as any other scope. But...

Try the optics area ----> FAQ -------> Mounting

Or use the search.... or better yet: http://www.google.com/cse/home?cx=010955838166721108978:qcbx5qqy10o&hl=en

Welcome...

The supplied rings are too low for use on an AR-10T -- the straightline stock design will not allow you to get your face low enough for a good sight picture.

I'd suggest either a picatinney rail riser or the Nightforce extra high Unimount (1.375") or rings.

I do have an IOR M2 mounted on an AR15 with a GG&G Accucam one-piece mount. I still have the original rings from IOR that I could use for the M2 if the GG&G is a good choice for the Nightforce F1 on the AR-10T.

On one hand, I hate to mess with the AR15 because it's GTG right now. On the other hand I just spent a pile of dough on this scope, and hadn't planned on another $150 or whatever for rings. What do you think?

Thank you. That's a beautiful mount. Does it have an advantage over the Nightforce one-piece mount, besides being a QD mount? They are about the same price. My GG&G Accucam mount was about $50 less, IIRC.

Would there be any reason NOT to use the GG&G mount?

Getting the scope the right hight for a good cheekweld is important and comfortable. To see if the scope is the right height and set correctly for proper eye relief, do this after lightly mounting scope/rings;
Close your eyes and then shoulder the weapon, get comfortable like you are going to shoot the weapon, now without moving, open your eyes. If you have to move your head any direction (IE;up, down forward or backward) then you need to change something to align your eye with the setup. There are so many people that don't get this right and they always have to adjust themselves to even see correctly out of their own rig.
You want this to feel "right on" which can make you faster, maybe even shoot better and is just plain comfortable.
Hope this helps..

Thanks for the tips and the welcome.

If my GG&G mount is a good enough quality for the scope, I am pretty sure the height would be comfortable. It is just right on my AR15, and the Larue rear BUIS on the AR10 are much lower profile than the ones on my AR15.

On question though. I have a line on a used , but unmounted NF Unimount, 1.375 height for a good price. The NF Unimount has a 20 MOA rise. Would that be a disadvantage in any way if most of my shooting was at 200-600 meters?

Maestro,

I have LaRue LT-135 (which is a little taller) and LT-158 (10 MOA cant) mounts for 2 NF scopes. If you have a reason to change or remove the scopes at times as I do, you will find that these mounts are quite good at return to zero when replaced. Nothing's perfect, but LaRue makes quality mounts. If you don't need to remove or swap out the scope for any reason, then think about a quality non-QD mount (NF, Badger, etc.).

I use TPS TSR High rings, fits perfectly if you have a 3.5-15x50.

TPS are good 2 go.

Glad to see you like the LT158. I just PM'd you asking about that:

<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body"> . . . I have their BUIS on this AR10T. Tyler at LaRue said the LaRue LT-158 would clear the flip sight. It's 1.4 inches tall, just .25 taller than the Nightforce Unimount.

(My GG&G mount on an ART15 20" is also 1.4" tall. and it is a nearly perfect fit.)

The LT158 has 10 MOA of cant. Since I will rarely, if ever shoot at 1000 yds, and since the NF F1 scope has a ton of adjustment, does this LT158 sound like a good choice for my setup? In other words, I would get SOME cant, but not 20 MOA, which I probably won't ever need.

Re: Mounting a Nightforce F1 3.5-15 on an AR-10T

Alright, I went with the LT-158. LaRue CS rules. I'll be mounting that be-atch on Friday.

P.S. How come nobody broke my <span style="font-style: italic">boys</span> for not posting this in the optics forum?

I'll check in after the weekend. Thanks again.

Larue works the best in my experience.

Re: Mounting a Nightforce F1 3.5-15 on an AR-10T

I have a Badger 22 MOA base on my POF flat top and it gives the perfect amount of raise for the supplied rings to get comfortable behind the scope. Also put my S&B 5-25x56 with 1" height Badger rings on there and it works fine also.

Nice. Which LT mount is that?

Re: Mounting a Nightforce F1 3.5-15 on an AR-10T

Maestro,

Never got the PM. Hope you like the 158. For your purpose, hopefully 10 MOA should be just about right. FWIW - you can tighten the QD lever tension (bolts) if necessary, but you really don't want to crank down on them too much. Otherwise, it will no longer be QD (LOL). Enjoy.

 

[Maestro Pistolero]

Re: Mounting a Nightforce F1 3.5-15 on an AR-10T

Got the scope this afternoon and the LT158 comes on Friday. Just about enough time to bone up on mounting, leveling, etc.

If Friday goes well, I'll zero it on Saturday. Thanks again y'all for helping a rookie.

I'm interested in hearing how many MOA(or mils) you have below zero.

I ended up adding a stock extension and using the 30MOA LT-107. I have only two mils left below my 100yd zero.

It will be mils. Playing around with the ballistic calculator it seems the the 100 yard zero will eliminate any reason to leave 'room' below my zero stop, right?

<span style="font-size: 14pt">OK, I have only bore-sighted it, But it appears that I have 1.5 full down-turns available on the elevation turret. So, about 15 mils, I guess.</span>

<span style="font-size: 11pt">Bore sighting was only 3 clicks off in elevation, so there you go. This scope and rifle combo rocks. I suck and I am getting 1 MOA easy. I only went out to 200 so far.</span>
