I am wanting to put a Nightforce 8-32 x 56 NXS scope on a .308 AR. Overkill? Perhaps, but why not?  My question is, which of the Nightforce reticle uses MOA instead of MilDot and will have MOA adjustments on the knobs? Is it the NP-R1 and is that superior than the NP-R2? I know and understand MOA, is it worth it try and learn MilDot instead? Then onto mounts, I would like to put this in a LaRue mount, which mount fits this scope or will I need to go with the Nightforce mount?
Thanks all! |

And yes, that is a lot of scope for a 308 |
| I am wanting this to be a 1000 yard target rifle. I have regular access to a 500 yard range and will have limited access to a 1k range. The 500 yard range I can regularly ring 4 MOA steel with irons and a NM AR in 5.56. So now I want to really stretch my legs out there to 1k. Why I am building this .308 AR. I just know I want to put high end glass on it and the NF optic I have shot through in the past blew me away. |

NF 3.5-15 x 50 with MLR reticle and milrad knobs. Plenty of scope for occasional 1000 yard shooting. After reading a metric shit ton on MOA or MIL I decided to go MIL. Whichever you do keep the reticle and the knobs IN THE SAME SYSTEM!
Edited to add: also you need to decide between First focal plane an second focal plane. FFP are more expensive. Only one NF makes in FFP model is the F1 and it is $2300. |

Thanks all! - Yes, I think it is overkill for a .308 AR for a 1000yds. Most who use that high of magnification for 1000yds shooting are Benchrester's and Belly Benchresters (F-Class), who focus on little groups with a small X-Ring. Most go with an NXS 5.5-22x for beyond 1000yds, or even 1500yds for that matter. - The only Mil based reticles Nightforce offers are the Mil-Dot and MLR, the rest are all MOA based with the NP-R1 and NP-R2 being the 2 ranging variants. - Is the NP-R1 superior to the NP-R2? Many will say so, but there are those who look at it and think that it's too cluttered. It's up for you to decide. - The standard NXS model scopes come with .25MOA adjustments. You have to specify if you want a ZeroStop or .10 Mil adjustments. The Mil-Dot is a reticle, the Mil is the adjustment value. - Is it worth learning a new system? If you already are familar with one, I doubt you'll find anything groundbreaking about the other. Also keep in mind who you shoot with. If your partner/spotter shoots MOA, you'll likely want to stick with the same system for ease in communication. - You'll likely want to use the LaRue OBR or SPR mount because they don't have any built in cant into the mount. Since the OBR has a 20MOA rail, using a Nightforce UniMount (which has 20MOA of cant built in) will compound the angle, creating 40MOA. This is a problem with the NXS 8-32x56 as you'll likely have a difficult time getting a 100yd zero. If you go with the NXS 5.5-22x, then that doesnt really matter due to the huge adjustment room inside the scope that the NXS 8-32x56 lacks. |

I recently bought a 5.5-22X with an NP-R2 reticle and zero stops. I got mine for the purpose of putting it on a .308. I never shoot at anything under 100 yards with this rig and to tell the truth, I think it's a bit over powered. Not a big deal to me on the bottom end since I don't shoot at anything close with the rifle. Having an 8X bottom end might turn out to be a hindrance, due to the narrow field of view. If the closest that you are going to shoot is 500 yards, it may not be a hindrance to you.
Although my scope goes up to 22X, I don't think that I've ever shot it set to that magnification (except for when accuracy testing). When it's set that high, the mirage is hellacious, even when it's cool out after a half a dozen rounds or so. I don't know what it's like with the model that you are considering, but on mine, the eye box gets pretty small at 22X too. I like my NP-R2 reticle. It's clean and isn't overly cluttered. Still, I'm kind of wondering if I might have been better served with the NPR1 reticle. The extra graduations may have made it easier for ranging at 11X. I went with an MOA setup because I'm just learning too and have a pretty good grasp of how the inch works. LOL. A lot of the guys I know that shoot .308 just to bang steel, without regard for group size, go with 10X scopes. Personally, I've been fine with 10X when I'm just shooting to hit a target and am not worried about how close together my shoots are. I'm running a 2.5-10X on my .223 AR and like the package. The 2.5-10X has an NP-1 reticle. I've never shot that rifle out past 300 yards, so am not worried about ranging with it. Guestimating to those distances isn't too hard. |

8-32x56mm is a lot of scope. I personally would not do more than a 5.5-22x on an AR10 308. I feel the 3.5-15x would be better suited for an Auto Loader. Auto Loaders are great for speed and at 15x it will give you a bigger field of view. At 22x the field of view is smaller make harder to do multiple in engagements at different locations. I have two AR10 / LR-308 and I run a 4-16x and a 4-12x. I’m a big fan of Mil on Mil scope but a lot of guys also like the MOA. The NF HI-Speed turret in MIL will take a 308 out to 1k in about one REV were in the MOA it will take about 2 REVs. I run a 3.5-15x50mm on my 308 bolt gun and it works great. Here is a video of one of my setups.  I hope this info helps you and if we can be of help in getting you a Nightforce scope feel free to ask.
