Cannot zero Photon XT 4.6x42S-long story

I had/have the same issue, but much bigger. I mounted the same scope on a Savage A17 semi auto .17 HMR, with a EGW 0 MOA picatinny rail. I have expensive night vision, but wanted something cheap to use for varmints at night around my buildings, hence the frangible .17 HMR. I first mounted the scope in UTG high QR rings. I could not get any closer than 6" low at 75 yards. I bought Sightmarks CJRK 1 piece mount and reversed it, due to the eye relief issue-still could not get close, still shooting low. I shimmed the back ring of the CJRK (under the base) AND under the back ring - that got me to around 1" low at the same range.
After almost a year with the gun still not really sighted in, the double shimmed set up started to bug me, as not being very secure. I decided to try a 20 MOA rail from EGW. I mounted the new rail, raising the rear to try to get to zero without shimming. I went out and tried to sight in at 60 yards, which is where I want to zero. I fired about 25 shots, and NEVER hit the target. Thinking I might not be understanding the funky electronic reticule, I adjusted from -30 (max) in the Y axis, and then +30 (max) saving the setting each time. I still never hit the target. By now, I am pissed. I took the rifle off the table/bags and walked 25 feet from the target. Shooting offhand, I shot about a 6" group, 6" low of the bullseye with the windage perfect.
I gave up, went home, and called Sightmark the next day. I called tech support. They were very nice. The guy there told me they do not recommend the use of a 1 piece mount, and that the CJRK mount would not fit the scope because the rings were 2mm too wide to fit within the tube of the Photon XT. I only wish I had taken a picture of it before I removed it. He argued with me, but what can you expect when a company's online manual says to turn the scope on you rotate the notched wheel 6 times when you actually push the button on the back of the IR illuminator? He told me I would probably need to return the scope.
Be forewarned, Sightmark does warrant the scope for 3 years, BUT you must have the receipt. I had to write the vendor to get it as I did not have a charge receipt from a little over a year ago. The day after I got the RA#, the scope went back.
In anticipation of its return, I ordered a set of Burris XTR Signature rings (not QR), with inserts to adjust +/- 40 moa up/down and left/right, from Brownells. I ordered mediums and hope they work because I also found out by calling Burris that their "medium" rings are actually lows. Burris measures their ring height differently. If I need to return them after checking them when the scope returns, Brownells lifetime satisfaction warranty will be tested.
So far I spent $35 for the UTG rings, $50 for a 0 MOA rail, $50 for a + 20 MOA rail, $100 for a CJRK mount and $100 for the Burris Signature rings If I added the $$ I spent on the mounts, I could have bought a Pulsar 550 and it would have the mount, but now I am in too deep and have to make this work.
While waiting for the scope, I called tech support again. The same guy I had the first time. told me to take the +20 MOA rail off and go back to the 0 MOA rail, mount the scope (once I get the ring thing figured out), and go out and sight in at 30 yards. Assuming I can zero there, he told me to move back to my desired 60 yard zero, and fine tune.

The Photon XT is a series of contradictions. By virtue of its lower end NV capability, it is meant to be used at short ranges with an external IR illuminator, but it is difficult to zero at short ranges due to the relatively small adjustment range. The objective is 42mm, but with the part that hangs below that, what height rings do you need to mount it? It's odd configuration makes it difficult to mount and eye relief is just as bad. I am considering putting both Burris rings as far forward on the scope tube and then mounting as far back as I can on the Picatinny rail to get the scope back far enough to use. Sightmark could have solved all these problems by charging a little more and incorporating a mount on the bottom of the camera like the Pulsar (others could still mount on the tube if necessary), but since they can't even correct their manual, and their employees have little real world experience with the product, I doubt they will.
I will say, as far as the unit itself, the picture through it is wonderful, especially with auxiliary IR, for the $$. If only I could get it to zero, it would be everything I was hoping for from this unit. To add to this debacle, in working on the return I noticed I should have had a lens cloth, video cable and warranty card, none of which was in the box. I have a sneaking suspicion that the vendor sent me a unit that was returned to them for the same reason-minus these items. Why should they deal with the return when they can re-ship it and let me deal with it? Anyone else had asimilar experience?
 

Cmatera,

The Photons have somewhat of a reputation of not zeroing well and requiring some adjusting. I currently have the 6.5x model and I first mounted it on a 0 MOA base on a Bergara bolt action .308 and I had the adjustment maxed out and still could not get the bullet impact to center. Bullet impact was way out, several inches low as I recall. I then installed a 20 MOA base and that solved my problem. Now the scope is fairly well centered (reticle centered in the view) with only a few clicks out.

On my AR, the adjustment (in order to bring to zero) has the crosshair way high and left in the view. It will adjust and I can shoot OK with it, but the reticle is nowhere near center which I don't like. It's odd to have a crosshair not centered in the view. If I were to switch the scope to my AR, I would have to come up with some other type of adjustment, maybe Burris Z rings with inserts or similar.

Your scope sounds like it has issues more than typical. Hopefully a new scope will work better, but also more than likely you will need to get rings or a base that will adjust properly and keep the crosshair as close to center in the view as possible.

I returned one scope (4.6x model) for another problem and was issued a brand new scope. I am aware of other PM members who have returned Photons too and have not had any issues with warranty. Customer service has been quite good actually.

One other thing the company does is offer discounts to veterans. They gave me a great price on a new 6.5x scope, cheaper than I could find from any vendor.

Here's my 6.5x on the Bergara .308.






Here's a target I shot at 94 yards. I used a rather large target to help with sighting in the daytime. I have since shot a better group than this target.







Got this Gray Fox at around 35 yards or so.







 
I believe so. I used a level before I installed it to make sure I was raising the rear. That's another thing. Do you think EGW could mark which end is up/down or include ANY installation directions for the $50 shipped they sell them for? The tech guy at Sightmark told me to remove the 20 MOA base, which I did. He said it should not be necessary and in his opinion, there was something greater wrong with the scope.
 
If when you get the new scope it still won't come up to zero, it might be an option to try the rail in both directions.

It does sound like you might have gotten a return scope from the dealer. Maybe this will correct your issues. The Burris rings should solve any problems I would think.

I definitely think between Sightmark replacing the scope, the 20 MOA rail, and the Burris Signature rings I will get the job done-eventually.
 
Update-Got the new scope same issue. The Burris rings I ordered were too low. I ordered a set of extra high@$117. If that does not get me on paper, I will conclude that the Photon XT, with its limited range and mounting options simply cannot be used on every rifle. For the $$ I spent on the scope and mounts, I could have bought a Pulsar 550 and it would have had a Picatinny mount on the bottom. Who would think that a scope with a great picture could be half the price and end up costing just as much and still be unusable?
 

Cmatera,

Hopefully reports like these will be get back to the company (Sightmark / Sellway) and maybe it will open their eyes and ears and cause them to do something about this sighting issue. Apparently they were listening about the lens cap deal and they do seem to have good customer service. This sighting issue is fairly common with the Photons it seems, and I know for sure it was an issue with my latest scope. I still can't mount it on my AR without the crosshairs being way off center, which is just unnatural.

Despite the problems, the Photon is not a bad scope "once adjusted properly." But like you say, if a guy has to spend so much for rings, base etc., not to mention the headache of getting it to work right, he may as well spend a little more and get a scope that works right out of the box, maybe even go with a Gen 2 scope.

Hopefully the new rings your ordered will make things right. Keep us posted how it goes.



 
Posts like these had me running scared of the Photon. I mounted it on a HR single shot and struggled with sighting it in. It was a combination of being new to digital cross hair and the non confidence I had in the gun.

I switched it over to my AR mounting it backwards in a Burris PEPR and had it completely zeroed in 3 adjustments. It responded better than most scopes IMO. I have the numbers documented in another post but the vertical Y axis was -23. If it proves to hold zero I will be more than happy with how it performs.
 
It performs great-IF you can get it to zero on a particular firearm. So far, I have tried a 0 moa rail, a 20 moa rail, a sightmark CRJK one puece mount (turned backward-eye relief is another whole issue with these scopes), extra high rings, extra high rings next to each other, and the wrong height Burris xtr signature rings. If higher signature rings with the 20 moa rail don't solve the problem, I could try Sportsmatch adjustables or FX No Limit mounts, but will probably give up and sell it all off. FYI, Sightmark does not recommend the use of a 1 piece mount, but glad you got it working for you. Tech support while friendly, has been useless, all they say is take it to a gunsmithof which there are none where I live. I can guarantee you no gunsmith would try all the things I have, and I have mounted/boresighted hundreds of scopes without problem.

The Photon XT performs great if you can get it mounted/zeroed, if you are flexible on the firearm you will use it on (I am not), f you are aware of its design flaws (limited mounting options, limited eye relief, and limited internal scope adjustment at the short ranges which it is made for). To others, just be aware that it's low initial cost and good performance for the price have the potential to turn into a money pit if things go wrong as they frequently do. A quick Google search of Photon mounting and Photon mounting problems will bear that out. Be aware that although more $$ upfront, there may be better options.
 
Best part is, I have other NV. I have a gen3 D740, a gen3 PVS14, and a FLIR LS64. I wanted this for close range semi auto shooting at close ranges for use around my buildings, in a round having a reduced propensity to ricochet. The Savage A17 fit the bill perfectly at a reasonable price for a special purpose gun.
 
I took all that into consideration based on the posts I read here both good and bad. I purchased through Cabelas who's return policy is pretty liberal. I didn't see the one piece mount non recommendation until you posted it earlier. I would also have pulled the plug on it long before I went through the a s s aches you've been through. I've overcome the mounting and sighting in issues. It's now about holding zero and reliability. I normally give opossums and coons a pass on my bait pile not this year so we will see how she does.


Did you by any chance try it on any other guns you have?

The main thing is you got it done. The scope I just got from Sellmark is brand new. Like always, I'll just sell it, take my loss and move on. Thing is I've been working on this for a little over a year, so I'm not sure anyones return policy is that liberal. Sometime you just can't get what you want-I'm OK with that, and happy for the guys who are using them problem free.
 
I struggled the same way getting the photon mounted on a Savage 22 mag. I finally got it half [beeep] mounted and sighted in but couldn't get it back far enough for proper eye relief.
Didn't feel comfortable shooting it the way I had to so I sold it. Wouldn't you know Michigan would change their night time hunting caliber laws and I could now mount it on one of my AR's and the problem would have been solved. As stated nice scope if you can get it mounted correctly. I feel your pain cmatera.
 
I feel for you guys but feel lucky I was able to get mine good.

cmatera did they give you any reason to not run a one piece mount?

Originally Posted By: pmackjefo/yotehunter I first mounted and zeroed it on a single shot H&R 223 like you and the instructions called for and I struggled, could have been the gun though. I was never happy with the results on paper. I hunted for a month with it and put a few down and a few misses, my confidence wasn't the best. I was hesitant on keeping it and moving to my R15.

I just moved it to my AR and was surprised how much better it was. To get the proper eye relief I had to mount it backwards in my Burris PEPR. 2 shots down the tube at 50 yards I was an inch left. I didn't bother holding the cross hairs I just moved it 2 clicks left and it zeroed. Next 5 at 100 yards were 3" high and 1" left and I was a little worried. Again I just moved the cross hairs in the required directions and was dead on. I wanted to move impact up at that point so I moved it down 1 click, next 5 shots were still not where I wanted to be at 100 so 1 more click down and I left it.

I really struggled with this on the H&R but my R15 was much more consistent and my shots reflected each change.





 
No, they did not give a reason for not recommending the one piece mount. They told me that when I told them I tried THEIR CRJK mount which was like $100+ IIRC. I reversed it like you did to try and get proper eye relief. I tried it the other way too to see if that was the problem but found no joy.
 
An update-I finally got the 1.5" high Burris XTR Signature rings and mounted the Photon. I had to try different inserts until I got where I wanted to be. Finally I am good. I am using an EGW +20 MOA rail, a -20 MOA insert in the front Burris ring, and a +10 MOA insert in the rear Burris ring, for a total MOA adjustment of 50. After chasing the bullet, my Photon settings are: x=0, y=+11. Was shooting off my gun cleaning vise; too lazy to get out my shooting rest, but it's good now.
