Default Ultimak Question

One day I'd like to go ahead and throw the money down on an Aim Point. In the mean time I'm running a Primary Arms Micro Dot on my 107CR.

Have any of you burned a Primary Arms red dot out on an Ultimak?

I have not but it does not mean its not possible.
If you use it how it was intended to, there's should not be any issues. If you are doing some test where you do massive mag dumps then it's not just Ultimak and optic you might worry about. Even original SF AK wasn't designed with that use in mind.

In other words, if you use your rifle like a rifle and not a machine gun there's nothing to worry about.

My holosun red dot sits on a midwest gas tube and it gets roasted about everytime i go to the range. I havn't tried any of my primary arms dots on one yet but i believe the pa dots are made by holosun

If it's getting roasted does that mean its still functioning properly despite how hard you run it or it gets roasted and shuts down?

I had two separate PA micro dots, both model MD-RBGII.
Threw one on an ultimak, and after it heated up the turrets ended up squishy and the optic was not holding zero. The dot would shift, and every 5-6 shots I'd have to dial it back over. Mount was solid, everything was loc-tited, and up until a point the optic did not shift. Then after a few mags, I saw my shots moving more and more off target, and through the irons, confirmed that the dot was moving.

Had that one replaced, and the replacement did the same thing.

I do have an Aimpoint T1 that I'm running on the same rifle now, same ultimak, and it's been solid.

That wasn't their advanced micro-dot that RobSki tested, though.
No. I bought one of those (advanced) for my AR, and it needed exchanged due to electrical issues that were present before the it was ever mounted to the rifle. The replacement has been great, and is now mounted on my Scorpion.
Would I put it on an Ultimak?
Based on my experience, probably not, even with knowing others have without issue.

That sucks you found that many lemons in a row. I've primarily run PA products and haven't had a single issue.

Had it on a WASR held up fine while it was on that rifle. Maybe only 400 rounds through the rifle with that optic on it though.

I put a TRS-25 on an Ultimak on a Romy and it gets toasty after a few mags. No problems yet. Don't think you'll have much problems unless you're running 5+ mags thru it as fast as you can pull the trigger.

I know, it sucks.
I hear everyone else talk about the good luck they've had and all I can think is, "Why couldn't I have had that same luck"?

Oh well, such is life.

I will say, they do have a solid exchange policy and very good customer service.

Didn't say it couldn't/shouldn't be done. More of a "if you want to maybe brand your hand or possibly toast the optic" precautionary warning...Besides it gets a bit screwy picking out the target thru the mirage that barrel heat kicks up.

I tested this today at the range i ran 5 full magazines through the wasr with the holosun very quickly. I let the gun cool and took it out to 300 yards i missed all 5 shots, I know the dot was zeroed before b/c i went 5 for 5 at 300 before hand. I went back to 25 yards and checked zero the gun was shooting 3 inches right at 25.

If the sight was mounted in a cowitness setup, you don't need to check zero at 25 yards if/when the dot shifted that much, it'll be noticeable right away without shooting it.

Tried to warn ya. Electronics do not like large amounts of heat. Never have.

This is how I see it....
Normally, one would carry 5 to 8 mags on them. If you were to engage in a firefight and fire off all the mags you have on you as quickly as possible...... the red dot and or it failing from heat would be the least of your concerns.

Learn how to move (conceal/cover/maneuver), fire for affect (not suppressive fire) and the Ultimak/red dot will do you well and not have any "heat issues".
A normal range session (where shot placement is the goal), I never had any problems with Holosun, PA or Aimpoint T1.

You guys have never heard of thermal drift? It's going to happen with any optic that is subjected to that kind of heat. I've gotten Aimpoints and Primary Arms optics so hot on an Ultimak that you couldn't touch the optic, hot enough to melt the o rings on the turret covers on the PA optic, but I've yet to kill an optic with heat. It does happen though.

I am using cheap PA on my Slr106f with ultimak, good setup but if you could avoid it with side mount it is better.

2 Red Oktobers and multiple carbine courses with my PA Advanced Micro Dot with an Ultimak on my SLR107FR. No problems.

I had a PA advanced micro on an ultimak and it burned up around 4k. Dot dimmed until its extremely hard to even see that its on, on high, in a pitch dark room. Replaced with a used t1 that ive since put 10k on and no issues and i dont expect any.

I don't own an Ultimak nor do I want one.

After investing in an optic I cannot see myself
subjecting it to that kind of heat, hoping that it doesn't get fried.

Just doesn't sound like a great idea.

No one is forcing you to get one, there's plenty of other choices out there.

With that stated, there's absolutely nothing wrong with even mid grade red dot sight on Ultimak if they are used like the rifle is intended to be used.
With many thousands of people have no issue and few of the ones who do, half or more are making up shit as they go.
Ultimak has been on the AK aftermarket scene longer then any other accessory and still is one of the most popular, if it didn't work well or cooked all the optics it'll be long gone.
It does cowitnessing better then anything else, it adds no weight to the rifles nor does it change the balance since that 5oz red dot is near the RSB.

I ran over 6K with Aimpoint T1 on Saiga/Ultimak, no issues, ever. Have a few Holosuns and Primary Arms red dots that also never gave me any problems.

I'll take Aimpoint's advice, thank you very much. You do as you please of course.

They say 160 degrees is the top end of their suggested
operational range.

From their website:

Quote:
Temperature range operation: -45C to 71C (-49F to 160F)

The only issues i've ever encountered with mounting red dots on the ultimak are issues that were solely the optics'. Ive never had one "burn out" on the tube but had optics die that would have died anyway.

Ultimak + even the bushnell trs will work fine if you use your AK like a rifle and not a machine gun on the IV8888 channel.
