I love the set up, best of both worlds, my EOTECH (I've used an EOTECH 550 since 99') is now on my ROCK RIVER M-4 at home. It takes a little training on the sight transition, but it's easier and faster than trying to shoot close urban targets looking thru an ACOG.

JPOINT has given us a pretty good deal on unit orders of the sights and the mounts or if your buying one for yourself, they give service members a discount also. The winged mount you need for the issue ACOG is the following:

[ JPA-TANSN adapter for piggy back secondary sight on Trijicon ACOG NSN scopes ]

It replaces the stock rear sight ring on top of the ACOG and bolts into the lower strap which is part of the ACOG body.

Quite a few ODAs in the Company have gone to this set up. Guys that used it in OIF loved it for giving a shooter the option of a long range optic and a close range one without having to change out optics, plus the JPOINTS survivied the rotation in the same working manner in which they deployed .

The same battery lasted the entire rotation, so long as one doesn't lose the "storage cover" which saves battery life when not in use.

Looking back at this thread, I would like to add that I like the J-Point, but do not like having to bring my head up off the weapon so far to acquire the secondary optic.

I recently saw an SF soldier running an ACOG at training, he had his J-Point mounted on a forend rail forward of the ejection port at the 1:30 position or so. All he did was to cant the weapon over to the left and he was on the J-Point very quickly. He was so fast and accurate with it, that I am tempted to try such a set-up myself.

Anyone know who makes these mounts?

TR, there is an angled rail mount in YHMs products;

The type of setup you mentioned, is also popular on the IPSC rifle side.

Thanks.

It looked a lot smoother and faster to me than pulling up your head to peer over the ACOG.

Reaper,

Sir, just wanted to let you know that I have been using an ACOG and an EOTech mounted on a 45 degree angle just in front of the ejection port for the last few months and it has worked very, very well. I had tried the JPoint on top of the ACOG at one time and found it to be difficult because of the need loose my cheek weld to see the sight. With the setup I have now rotating the weapon 45 degrees take a milisecond to change sights especially after a little practice.

Right now I am running a GG&G rail that enables you to mount a rail at 45 degrees, however YHM makes one that fits a standard rail system (as mentioned before) and I just found out that a place close to Bragg makes one similar to the YHM accessory. I haven't got a good price for you but I was looking at getting one for my personal weapon.

That looks a lot like an ACOG and EOTech in your pic.

Was that pic taken in December, BTW?

It's a TA47-2 ACOG on a LaRue mount with the EOTech 552 up front. By the way I've had the EOTech for a year with no problems in direct sunlight. Although we had a problem with one where the rheostat broke. EOTech replaced it with no problems.

Just a few quick questions on the Jpoint. Is it durable and how long does the battery last? The reason I'm asking is because I am putting together an AR10 with a medium lenght 18" barrel and I have been considering mounting an MRT or NXS 2.5x10 24mm scope on it using ARMS rings and using a rail ring to mount a red dot in front of the turrets. I've looked at the specs on the Jpoint and also the ATN ultra light digital. Size and weight are similiar although the ATN is a hair larger. I am leaning toward the ATN because it allows for 3 different reticle types and it's about $75 cheaper. Any opinions on either or any other suggestions. Thanks... TonyY

**The Reaper** · 01-24-2006, 12:35

I understand that the J Point is more durable than the TASCO it originated as.

For mounts for an ACOG, I have the ARMS #19 ACOG and the LaRue, I would consider comparing the two side by side.

For a QD mount for a 1" or 30mm tube optic, I currently have ARMS #22s, but have handled the LaRue SPR and think that the SPR mount may be a better platform for everything but precision long range guns, where a Badger Ordnance type ring would be superior.

Just my ,02, YMMV.

Reaper, for another mounting option for a tube sight I use a mount that Mounting Solutions Plus came up with. It is a 9" Pic rail with up to 30 MOA milled in that uses two ARMs throw levers for attaching to an AR Rail. On this I use Badger rings and a MK4 M1 10x. I switch that off an on of an AR that I have that I normally use a CQT on with the ARMs quick release. It's a lot easier to see things at 800yds with a 10x scope than with a 3x. I've never had a zero problem switching from one to another. On my CQB gun I use an Eotech with a LaRue Eotech quick release on and I've never had any issues with that either.

Tony:

Not sure if you already bought what you want. I have one of the ATNs -- the model before the digital one -- actually it is a holographic type of system. It didn't hold up well in weather conditoins under about 50 degrees. Would start to fade out and then simply go blank in temps under 40. Changed batteries and the same thing. Back in temps over fifty and it would work fine.

All dot sights will lose their dot when aiming towards the sun to various degrees. The ATN is more sensitive to this than an M-68 or a C-More.

The ATN I have uses external adjustments for zero. I would think that would cause problems in bad weather conditions but it worked out fine. Also, the zero only changed about a minute when switching reticle patterns. That one surprised me greatly. I was expecting gross errors and they didn't happen.

I think that the elevation and windage system was poorly made. Sometimes you can feel them 'click' and other times you can't. Poor materials and machining. However, if you crank right or left windage, up or down, it goes in that direction. Don't depend on it being real precise in these terms.

I really appreciated the various reticle patterns on the system. They worked out very well for me. The various patterns were clearly defined. No double images or bleeding of the reticle pattern. Very practical for different uses.

The conditions that I normally deal with are cold (40's) with fog, rain, or sleet. Must be the worse possible conditions for any sort of optical sight. If they aren't made real, real well -- they won't hold up for a day.

My two cents worth.

Gene thanks for the feedback. I haven't purcahsed anything yet. I'm still researching it. The Docter or Ziess sights also look like they might be a good choice although the price goes up considerably.

TonyY: In regards to the Jpoint's battery life - I have heard a range of 2-3 years from a few people who have had experience with them. I am not sure if that is with a large period of time in "hibernate" mode with the cap on or not.

I have seen some interesting mounts that replace the rear BUIS on a TA01NSN with the mount for a jpoint, but with protective wings on the side, not sure if it was mentioned yet or not.

The competition shooting canted sighting mount seems workable, and while I have yet to even add a railed forearm on my carbine, tilting my weapon left does seem shootable.

All interesting stuff to keep in mind when I start working with optics.

TitratetoEffect · 01-28-2006, 08:14

The two sight mount system is very usable especially if you get a little practice with it. I have been running an EOTech out front and yesterday the damn thing took a dump on me (it's lasted over a year). I have had no problems up until this point. I do want to try using a Docter Optic sight out front it is a lot smaller but I don't have much experience with it such as its range or durability. I read on their site that they make a military model, so we'll see what they have to offer at the Shot Show.

Recently, I got a J Point on loan, it retails for about 250 bucks but it is completely plastic. I don't believe it is the indestructable plastic or polymer at that. The retailer stated that the battery lasts for a long time as mentioned before but wasn't able to get any firm numbers. It just didn't seem like the optic was tough enough for the work we do.

Here is a pic of my set up.

uberalles,

"I have heard" doesn't cut it on here, unless you have first hand experience don't post.

Thanks for the feedback on the Jpoints. I try to avoid plastics and I always hated carrying batteries. I rather carry one of those hand crank generators for the 109. Well maybe not. I have one of those military Eotechs with those N batteries and they claim about 70 hours of life. Well I guess that's on the lowest night vision setting because in daylight I only seem to manage about 30 hours before it's time for new ones. But I don't use my CQB gun for any long periods, only when I'm in a class or something like that. At the time the shorter model appealed to me because it gave me more mounting options with BUIS.

Phil I'd be interested in some feedback if you come across something from Docter at the Shot Show.

Thanks. TonyY..
