Swap day scope with night scope? Accuracy question.

I have 2 scopes that I would like to interchange on one gun. One is a night vision scope, the other is my Bushnell rangefinding scope. Both attach directly to AR rails. I was thinking of using a Larue Picatinny quick release riser and use one for each scope. Of course I would be sighting each scope in with the new rails on the rifle. My loads are good for it and it is extremely accurate on its own with my Bushnell now.

Would you trust the accuracy of these rails out to about 300 yards? If not, then I will just put my night vision scope on my 6.8 and leave it be. But I am not having the greatest luck with that gun so far in the accuracy department. And I can't put a new upper on it that I want before this hunt. I also haven't gotten what I need to reload for it yet either.

If not the Larue system, is there any others that would be a good choice?

Thanks
Chris
 
Right. The Larue company advertises that taking the mount on and off has no effect on accuracy once re-attached. I am just wondering if people actually have seen this in practice. If this is true, then I am willing to spend the $250 on the mounts.

I will have them in my padded range bag when not in use and when we transition from day to night hunting, I want to swap to the new NV scope. Then back again over the coarse of a couple of days. Just looking for some input from those that have used simialr devices. I have also got a Eotech 557nv that I will be swapping out with it in Close cover areas. It holds zero really well when removed and returned on the gun, but I am just wondering about the Quick detach models of rails. I didn't want to carry a torque wrench around to change scopes just to keep my zero.


The obvious answer is more rifles, but I have great success with my bushmaster and don't really like to switch rifles during the hunt if I can help it.

Never seen it , might work, but i couldnt make myself go hunting without checking it. I would have to see it with my our eyes and do it a few times before i would trust it to go hunting.

Maybe someone else has had some dealing with it.
 
Exactly my thoughts on it. I'm not looking for 1000 yard accuracy, but 300 is normal for my hunting and the night scope will be good to 200 or so.

Maybe we will hear from some guys that know soon. It sure would solve some problems for me.

Here is what I am looking at -

They claim a guarantee of no loss of accuracy. And Larue is a very respected product.

I use Warne Quick Detach rings on my competition AR to be able to change from my EO-Tech, to my 2-9x scope, to my 6.5-25x scope...as needed... They all hold 'zero' within 1/4" at 100 yards...and that may be due to my vision, rather than a shift in the 'zero'...

With the EO-Tech:

With the 2-9x: (Same rifle before paint)

The Warne rings are a lot less expensive than the LaRue mounts.. I have one on another AR and like it, but wouldn't want to invest more money on them..to accomplish the same result..

Ok great. So in theory they work. In this case, both scopes are not traditional tube style scopes, but instead are like the ones below. This is the reason I need a rail instead of rings.

Since I have a good flat shooting accurate load, I would feel more comfortable using the same gun and switching the scopes out. If that is feasible.

Thanks for the input OldTurtle. Anybody else have this result?

My LaRue mounts have returned to zero every time I have taken them off and then reinstalled on the same rifle.
 
My Rock River one peice mounts hold zero perfectly. I have zeroed the scope and took it off and put it back on and put rounds back in the same hole. They don't guarantee that like LaRue though. I was just curious because I was wanting to do the same kinda thing at one point with my rifle. LaRue makes an exceptional mount though. One day when I get rich I will have one. Hopefully that happens sooner than later.
 
Assuming you have a flattop upper, with good mounts it will work. I do it, although I like to take a practice shot just to be sure, if I can. Sometimes you can't. If the night vision scope in the photo is what you'll be using, I have doubts about you taking a shot at 200 yards at night. Depends on conditions I guess.
 
Using the LaRue system should work...but I'm just curious why you couldn't get a 2nd upper? You're willing to buy 2 mounts at $250 a piece...I would think that for $500 you could have a quality upper in your hands tomorrow if you wanted.

Not knocking your methodology...just curious.
 
JB55, The scope is the same one and I am seeing great reports on these scopes and will have one in my hands today after 1pm. I also ordered the Variable-Da Torch from TVNC. Looking at videos on Youtube that are created from within the scope, I believe 200+ is possible. It is the Pulsar Digisight N550 I will know for sure tonight though.

TCS, The mounts from Larue are only $125 each. But what you say is valid, I would like to have another upper for the night trip, But I don't have time really to develop a new load and go through the motions of loading for a new upper before I leave for the trip. It took me about 2 months to get the load that works well out of my Bushmaster. There is certainly no need to change it.

Like I said above, I have a 6.8 complete AR, but don't want to use it if I can help it. It is setup for my Close in thick cover areas and home defense.
 
Understood...I don't have enough experience in handloading or building uppers to know if you built one the same as your other upper if it would shoot well enough with the same load or not. 200 yards is not a terribly long distance so you might be able to get by with the same load. Who knows. Either way, the LaRue setup has a lot of positive feedback. Haven't used it myself but by most accounts you should be fine.
 
cj,
Curious as to how you make out with that NV scope and whether you can see well enough with the Torch to be able to put the crosshair on the yote at 200. Let me know.
 
I have several of the detachable A.R.M.S. mounts and I can tell you that they stay on zero with no noticeable shift. I've shot thousands of rounds over the years. I sometimes switch out several times a day and carry them all in one case. This makes it handy traveling in the back country on snowmobile or ATV.

I was going to say ARMS rings/mounts, as well. But, TheGuide beat me to it. They are EXCELLENT quality, though, not inexpensive.

Thanks for the info on these mounts guys. I like the ARMS mounts but the price difference is enough on the Larue that I am going to get them. I thought about the VFZ mounts that use the bolt instead of the lever, but in the interest of switching quickly, I am getting the levered model.


JB55, I went out last night and used the scope in a field that was 230 yards from end to end. We had a little less than half moon and I could easily see across that field with no IR illumination at all through the scope. My wife went with me to see what I was doing and she was playing with the scope and picked out a raccoon milling around at the far end. I then turned on the torch and you could clearly see the coloration of the raccoon and the stripes and facial features even at 220 yards. In my book, this is Night and Day (Pardon the Pun.) better than the Gen 1 scope I had and well worth the money.

The true test will be when I get to Texas with no moon, but from the performance of the Torch that I saw last night, there will be no problem tracking the targets even if not looking at me. It is very easy to pick up movement in the scope and could even pick out individual blades of field grass at over 150 yards. I would like to see a real comparison of it to Gen3. I'm guessing it is pretty close based on photos I have seen of Gen3 devices. That is dependent on the illumination you have though. I plan on using the video out feed while in Texas to capture the kills on Video from the scopes point of view. This should make for some interesting footage.


The only complaint I have with it is the focus knob. I is pretty far forward and I wish it had a bit more travel for fine focusing. But it does focus well with what it has.
