Great question! You might want to take a look at the NX6 5-30X56mm F1 (34mm body tube). It's relatively close to the specs of the ATACR 5-25X56mm F1 (34mm body tube) you mentioned but in the NX Series Family.
Yes. All of our optics are built with the same durability in mind. All of our optics are impacted to over 1250 Spike G's which simulates over double that of a .50 cal recoil. We run the same inspection and checklist on ALL of our optics to ensure they all stand up to the Nightforce name.
That is a very subjective question, we believe our optics compare favorably to any optics on the market. We will stack our ruggedness and repeatability against any other optic.
You will need to contact Spuhr.
Not knowing for sure what the diameter of that specific barrel is, we'll have to give you the information below.
If the diameter of your barrel is .825" or smaller (Sendero Style), you can go with the 1" Medium rings- Part number A223
If the diameter of the barrel is over .825", you will have to go with the 1.125" High rings- Part number A224
Then ATACR 5-25x56 comes with either Mil reticles and Mil turrets or MOA reticles and MOA turrets.
Either our unimount A257 1.44" or A357 1.5", or the A681 Ultramount would be our recommendation.
The NightForce ATACR 5-25x56mm F1 ZeroStop Rifle Scope with the Tremor 3 Reticle is model number C574.
Yes you can switch the illumination in the reticle from red to green. For that particular set up I would recommend a ring height of 1.125". As with all mounting hardware these are just my suggestions, there may be factors I don’t know about and there are many other ways to mount this optic to your rifle. I highly recommend mock mounting everything first and double check your dealers return policy in case there is something about the set up you wish to change. If you have any other questions please let us know.
This Optic's elevation range is 35 MRAD.
