    Wanted to try something out with ANVIS 9, a single PVS14 and dual PVS14s since I have all 3 setups. Was curious about something with the Hi Rise but wasn't willing to bet 230$ on something that may not work the way I am thinking it may/may not.

    Would like to borrow one to try, and if you were looking to unload it, I may buy it off you instead. I'd be more than happy to pay for shipping both ways.

    Not sure if you're interested, but I have a Larue EoTech QD mount that accepts PVS14, also with a QD lever. I sent the EoTech back, never really used these parts anyway, so they're like new. The PVS14 ring and the mount. If you used any sight where the reticle is about the same height as the EoTech, it all lines up. For instance, an MRO with the medium height base will work.

    It essentially turns the PVS14 and a red dot into a NV optic but I just use PEQ's for that. If you want it, let me know, I'll let it go for a good price. It's just sitting here.

    It's not as tall as the KAC part and looks different but otherwise it's the same thing.

    Are you talking about the mount for the PVS14? I actually need the mount for the T1 because the PVS/ANVIS is all helmet mounted. Mounting a PVS to the gun is not going to help me :p
     
    What is it that you're trying to accomplish/test?

    ~Augee

    I've been shooting people at night (dont worry, theyre still alive). They see the laser/illum from my PEQ15 because they have nightvision too so my advantage goes to shit unless I'm shooting at them with a bolt gun and PVS30 where there is no active illum/laser to aim.

    Was curious about passive nighttime pew pew in certain situations with my T1 even though the whole 'aim down your RDS with nightvision' is retarded 95% of the time. Just wasn't going to blow 230$ on something I'd put on the gun and regret about 30 seconds later. Also wasn't going to be one of those plebs that bought one, tried it out and sent it back a day later for a refund.

    Well, the mount is for an EoTech and there's a railed section behind it that you can mount the PVS14 to so there's two pieces --a QD mount for the NODs that works on the head mount even with strange shit like dual dovetails and INVG's, then there is a QD mount for the sight itself with a section of rail behind it similar to the KAC part but different. With an MRO and a medium height riser, the dot is spot on. In fact, any sight that's zero co-witness (not plus or minus) lines right up, I did the math but can't recall the value off hand. But it was made for the EoTech.

    I was wondering why you wanted it too, I figured you used a helmet mount and a PEQ like me. My ex wife wanted it and that's how I ended up with it. I guess you can mount a magnifier on there too.

    When I used to train SDM's we used PEQ2's (some still had PAC4's) and we put chemlight necklaces on E types at 300m. Superimpose the ACOG reticle over the dot at 300 looking through the ACOG with the PVS14. If you have a good zero, won't be many shots till you nail the chemlight. It's minute of man consistently. SOP in our unit was to treat the PEQ as a weapon, if it goes off and someone sees it, that's an AD same as a rifle shot. So you tap the laser only when you shoot. His buddies with NODs will still see where it came from. Low power isn't as bad, doesn't usually trace, but you still see it.

    I also farted around with aiming through the ACOG with a head mount PVS14. It's a pain in the ass but it can be done. It's probably worse than using a pro mask or shooting left hand under a car in sideways prone. Never tried it with the M68 for some reason...

    So mounting it on the rifle, behind a red dot, is nice IF that beam downrange is a problem. I mean, what else can you do? One day I'll get a clip on when I can afford it, after I buy ANOTHER damn house, but short of that a 14 behind a red dot is the way to go. I wouldn't try to mount one behind an ACOG and you don't want to use a 14 behind magnified optics in general but a red dot? Yeah, for what you are trying to do it's the only way.

    You'll wanna be sure your red dot has the night feature so it's not so bright. I can't remember if the T or H has that.

    This is really where thermal shines though. One day, one day.

    You're stuck on old paradigms.

    Passive use of RDS through head mounted NV has been a TTP for quite some time now for many of the exact reasons you are now thinking of trying it to the point that it is now the preferred method for some professional users.

    If you want to try it as a "proof of concept" before investing in a dedicated mount like the KAC Skyscraper, you can simply get a cheap Picatinny riser from CTD or Amazon to try out and see how the added height works for you:

    https://www.amazon.com/NcStar-AR-15-Weaver-Riser-4-Inch/dp/B00BLDJZM4

    ...though it's not something I would particularly rely on for hard use or retain zero.

    You could also go with a slightly more expensive riser from Wilcox, KAC, LaRue, Leupold, Hahn, etc. that would be more "duty grade" without being requiring you to buy another mount, especially one that is exclusive to the Aimpoint Micro pattern--the whole KAC Skyscraper/Redback One mount grew out of Jason Falla using a lower 1/3 cowitness mount on a LaRue 5/8" riser.

    Just for reference, a quick chart of mount/riser combination heights:

    Absolute cowitness mount = ~1.54"

    Lower 1/3 mount = ~1.7"

    To clear an AN/PEQ-2 or 15 = ~1.93"

    .410” riser + Absolute cowitness mount = ~1.95”

    .410” riser + Lower 1/3 mount = ~2.15”

    1/2” riser + ABS mount = ~2.04”

    1/2” riser + L1/3 mount = ~2.2”

    5/8” riser (or HK416 upper + .410” riser) + ABS mount = ~2.17”

    5/8” riser + L1/3 mount (or KAC Skyscraper mount) = ~2.33”

    3/4” riser + ABS mount = ~2.29”

    3/4” riser + L1/3 mount = ~2.46”

    (height measurement is from the top of the rail to the centerline of the optic)

    Stryker:

    That only rises it .275; the KAC T1 aimpoint mount I have already puts it up higher than that. The Hi Rise is 2.33 according to the description.

    I think this is where the Hi Rise comes in because as retarded high as it looks, it puts the T1 high enough so when you have an ANVIS or whatever on, you can look through it with your right eye as it'll be high enough to where you're not running your ANVIS/PVS into the gun and you're not having to do the head down/eyes up maneuver where right now, I can BARELY make out the T1 dot with it almost to the absolute top of the picture through the tube, which is total garbage as far as trying to aim.

    This would basically only be for duals/ANVIS 9 because when I wear the PVS14, its always been over my left eye as I can at least (or used to be able to) see my Aimpoint or EOTech through the right eye if I needed to turn the lights on, or if I wanted to aim through the RDS without the laser. I also used to angle the PVS14 slightly upwards especially for this. The problem started when I started screwing around with ANVIS after years of fighting with a single PVS over my left eye.

    Or are you thinking to play stack the LEGOS as far as mounts + risers?

    Which mount specifically are you using currently?

    I'm talking about putting your current mount on top of a riser, not switching mounts to the riser mount.

    Jason Falla's optic setup prior to the Skyscraper mount--KAC Micro mount on a 3/4" riser:

    Knights_Armament_Company_Redback_One_RB1_KAC_SR-16_E3_CQB_MOD_2_11.5-inch_Select-Fire_Tactical_AR-15_SBR_Short_Barreled_Rifle_David_Crane_DefenseReview.com_DR_3.jpg


    High rise optics have been in use for quite some time, and come with a number of benefits, especially for fast moving and dynamic engagements, which is why it is seen most commonly with RDS, and to a certain extent LPVOs, one of which is use with head-mounted NVDs--even a small, 1/2" riser can make a tremendous difference compared to more common absolute cowitness and lower 1/3 cowitness sights.

    Yeah I was just doing the math on it.

    The mount is the KAC QD Aimpoint mount with both spacers in, which says it puts the center of the T1 at 1.525. The KAC Hi Rise says its at 2.33.

    So to mimic the Hi Rise, using the .725 spacer would put me at 2.275 which is close enough as far as a quick and dirty test.

    So we shall see. I just need something significantly higher with the ANVIS 9 to where I can look through the RDS instead of having to do this weird angled, head down/eyes up maneuver which really isn't very repeatable.

    Well, perhaps my idea wouldn't work for you. Worth bringing up. Basically it was designed to co-witness an EoTech and allow use of a 14 to piggyback. But that height you mention, yeah, I'm pretty sure it won't bring your site up that high without "staking the legos" as you put it. It would require a riser to reach your height and you may wind up with a Frankenstein setup. How tall I can't say off the top of my head.

    I just thought I'd bring up an alternative, if it worked, cool, if not no skin off our asses! Good luck with your endeavor.
     
    Use of passive sighting may require you to change your head positioning on your weapon a little bit, especially if you’re accustomed to “nose to charging handle” style shooting to avoid hardware impedence, but tall sights (using risers and/or tall mounts) makes it much easier for most people—again, even the seemingly insignifant increase in height provided by a 1/2” riser is usually enough for most people to mount their weapons fairly comfortably along with slight adjustments to head position, while the height difference may seem small, the change in angle with your eye being the vertex can make a huge difference when you extrapolate that to the end of a device that may be ending 8-10” in front of your face depending on how you set the eye relief.

    Also, while it’s only tangentially related—you may also want to try passive aiming when using a monocular by mounting it over your dominant eye. There are many good reasons to do so, and while the use of the non-dominant eye and the day sight in an “occluded sight” style has been popular for a long time in the past, it is more of an ad hoc solution that’s rarely effective beyond close range engagements due to the POI shift that most people experience when using day sights in an occluded capacity—this is natural given that your brain is superimposing the dot viewed by your dominant eye over th image being seen by your non-dominant eye, you may want to refer to the “DT vs. ST” discussion below for more on the importance of the fact that your two eyes in fact see slightly different images. Dedicated occlusion sights like the OEG and Singlepoint work because you are zeroing them in an occluded state, and adjusting the reticle to that state, but most modern day sights are zeroed with the intent of looking through the sight and superimposing/projecting the reticle onto the same image that the dominant eye is seeing.

    Again, old habits can sometimes die hard, and there’s no shortage of people who will say “well I fought this way when I was in Iraq/Afghanistan a decade ago, and it worked, so you’re wrong, and there can’t possibly be a better way of doing it!” so YMMV, but it sounds like you’re at least beginning to see why first hand some of the reason why new aiming techniques are becoming more important and are willing to try something new.

    have you considered a offset 45* mount? for close engagements it works great, should roll the weapon down away from your nod enough to serve your purpose

    Most 45 degree mounts mount the optic even closer to the bore line/receiver than standard height sights, increasing, rather than decreasing the likelihood of hardware impedence, especially if you try to use your dominant eye with duals, as you’re now rotating your weapon to place the day optic exactly where your non-dominant tube should be.

    45 degree offsets can work, however, if you opt to use your non-dominant eye with the offset, and rotate the weapon from the stock toe rather than the centerline to place the optic in front of your non-dominant eye.

    i would agree with your typical 45* mount on a handguard. i am more talking about a offset mount that is utlizied on something such as a spuhr where everything is already high overbore. i find with your nod on your dominant eye and rolling the weapon inboard 45* to comfortable and usable like that. ymmv
     
    I’m tracking now, yes, mounted offset to the optic, I would agree—I was thinking more in terms of a “conventionally” mounted offset sight off the receiver or handguard.
