do you have to remove sight for battery replacement?
1067009
Yes and no........it is necessary to remove the sight from the mounting plate which stays screwed securely to the slide. After replacing the battery into the underside if the sight, the sight will remount and return to exact zero by means of the registration / alignment pins along with the exacting alignment of the mounting screws. So, if your concern about removing the sight to replace the battery would require re-zeroing, your concerns are unwarranted. Mine is mounted on a FNX-Tactical .45 and it performs incredibly well...just like all Trijicon products. Buy it and enjoy much more accurate shooting. I hope this information has been helpful.

Yes. The battery is behind the base plate. Don't let that bother you, the battery last for years....

Replacing battery is not recommended..It is basically a sealed unit...no screws to disassemble...I have had mine for more than a year and use it nitely and still shines bright !!

Yes your rear sights are left installed. However you can no longer easily look/use them.

depends on the firearm. In most cases you need an allen wrench to take out a locking set screw that holds the old sight in position. you will also need a Brass punch to drive the old sight out of the dovetail. BRASS not steel unless you like marring and scratches.

Yea, getting the old sight off is a mother bear , but once you do , you'll have to file fit the front sight base slightly to get it into the dovetail. I love these sights.

Yes . There is a lock on the case between the photo lens and the on-off switch. From there you can just start popping the catches down the long side. When you get the cover off there are two (2) locks that hold the battery in, one will stay open and one is spring loaded. Tip the battery out and replace it. Reverse procedures and your done. Hope this is helpful

Yes, I actually changed mine out for a Tritium sight. Worked fine. This removeable sight has all the functionality of a standard A2 sight.

Well, the documentation doesn't say. I've had mine about a year with the original battery and it still works. But, I've only had it to the range a couple of times. For that reason, I don't know how long the battery will last if the sight is left on for an extended period.

If you have a tiny Phillips head screwdriver with a magnetic tip (like the ones that are used for eyeglass adjustments), you should not have a problem. There are 3 tiny phillip head screws that need to come out to remover the backing. Once the backing is removed, there is one more TINY Phillips head screw that "holds" the battery in. Once you have the right screwdriver, it can be changed within 3 minutes.

Yes. Easy to remove. You can replace it by buying another one when it eventually konks out as well. But the battery on mine has been good now for a long time. Havent had to replace it yet.

No. The battery slots are more like holes. Removing one has no effect on the rest of the batteries.

It requires a battery. However battery life so far is excellent and the sight allows you to co-witness you BUIS.

It looks like it can be removed, but it is not meant for use that way. The battery is stored in the stock, so you won't want to remove it.

Yes batteries are included and it if for any gun chambered .223 or 5.56. Yes, you have to take the batteries out to turn it off. You should not use it much. It only takes a few minutes to bore sight a gun.

Yes it does. I actually just removed the pin that holds the sight on and replaced the sight. Made it much easier to install by not removing the base. The front sight is a pain to remove. I love the sights though. Huge upgrade. I would suggest having a gunsmith install.

Nope. Battery has to be taken out. Screwing top can be a little tricky due to the fine threads. Still, the flashlight is really bright, like a police vehicle's spotlight. Best flashlight I bought plus its made in the USA!

It can vary. You might find it helpful to pin down the watch and use a wrench on the coin to get the back off. Usually sticking the wide end of a toothpick in and twisting does the trick on the battery. Batteries vary slightly in fit. Now some batteries have a sticker on the back which needs to be removed. The manual recommends professional service or at least a replacement seal if monitor is going to be used underwater.
