    Rifle Scopes New Elcan Specter OS4X

    If you find one, hold onto it. I still have mine after all these years. Hundreds of scopes go through my hands. Very few stay here permanently. ILya

    New GPO Super Compact MPVO 4-16 x 44i FFP mil shipping late May

    I have one here and started looking at it. It looks like a pretty nice scope so far. The reticle is not ideal, but workable. It is indeed odd that they did not just put the LRi Pro reticle into this one. The reticle they have is, for all practical purposes, P4FL without the stadiametric...

    Vortex RazorHD Gen III 6-36x56 vs NF ATACR 7-35x56

    @Covertnoob5 would you mind chiming in on that?

    Rifle Scopes Blinded, Randomized scope testing

    A collimator can be a lot more than that depending on the performance you are looking for. For riflescopes, the collimator is not all that expensive since you do not need very large optics. ILya

    Rifle Scopes Blinded, Randomized scope testing

    Image quality can be objectively measured. All you need to do is pony up some cash for the right equipment and training so that you can measure away. Now, depending on what exactly you want to measure, you are looking at mid-to-high five figures and on up from there for a turnkey test station...

    300-600 yard optic?

    If you want to avoid chinese-made optics and you are on a budget, your options are somewhat limited. You correctly identified SWFA fixed power scopes, although I'd be looking at the 12x. There are a few Phillipine-made scope out there you can take a look at, but nicer ones end up relatively more...

    Question about member regarding optics reviews

    It seems like a reasonable lineup. If you are primarily shooting at the range, rather than taking this setup into the field, there really isn't much downside, aside from price and esthetics to going with a larger/higher magnification scope. ILya

    Question about member regarding optics reviews

    Anything specific you are wondering about?

    Will NF design a wide angle lens?

    Well, for what it is worth, it is entirely possible that the marketing/website people who put the specs up do not understand any of it and do not care enough to correct it. In other words, if I were to choose whether it is willfull deceit or general purpose incompetence, the latter is usually...

    Will NF design a wide angle lens?

    No. 23.5 deg AFOV violates Swaro patent

    Will NF design a wide angle lens?

    Every single ATACR 7-35x I have ever seen tunnels below 8x. ILya

    Why are all scope reticles black?

    Will NF design a wide angle lens?

    I assume that is 6.4mrad from center to the edge, right? Assuming the magnification calibration is accurate, that translates to ~23.5 degree Apparent FOV and 3.86ft at 100 yards instead of the listed 4.6ft. ILya

    Will NF design a wide angle lens?

    Just measure the FOV with the reticle on highest power

    Why are all scope reticles black?

    Black light? That would be a near trick. Generally, you can have a larger reticle feature become visible via a beam splitter or a phase grating

    Will NF design a wide angle lens?

    I have the Gen1. It does have wide FOV.

    Will NF design a wide angle lens?

    The wide angle lens discussion is probably worth a livestream as well. Maybe next week. I'll do one on why reticles are black tonight or tomorrow. A couple of observations: to make a riflescope with a very large apparent FOV, you need either a very large eyepiece or shorter eyerelief. There...

    March-FX 5-42X56 HM Gen 2 with writable turrets at SHOT Show 2025 along with new concepts scopes

    I thought Tangent shipped their scopes with ARDs. Tenebraex ARD works very well.

    March-FX 5-42X56 HM Gen 2 with writable turrets at SHOT Show 2025 along with new concepts scopes

    Well.... The business with translating vs non-translating turrets can be argued both ways and I am not entirely sure which is a better way to go. From impact resistance standpoint, non-translating turrets are usually a better idea. The way most of those turrets are designed, if you drop the...

    Why are all scope reticles black?

    This is a really good question and it never occurred to me that anyone would be asking it. It is one of those blindingly obvious things that, looking at this thread, is apparently not obvious. Now that I think about it, unless you have had a chance to think about how we see things, it probably...
