A rock-solid platform for your premium optics. With the increasing popularity of the AK based rifles in three gun competitions, the need for a handy, light, completely reliable high speed sighting system has resulted in the UltiMAK M1-B optic mount. Its Picatinny rail is positioned well below the iron sight axis, making this the lowest optic mount available for the AK. With a tubular sight mounted low, you will be able to use your optic without a comb riser and still use your regular hold. The system allows for co witnessing (the ability to use your iron sights right through a 1x sight as a back-up sighting system) when used with a tubular reflex sight. 

Note: For AKs that originally used gas tubes that do not have holes in them, such as the Romanian WASR-10. Will be slightly shorter than original gas tube, this is normal and will not effect function.

  • AK Variants with standard weight barrel and standard removable gas tube (roughly 7" in length, will vary slightly between rifles). 
  • With separate barrel shims, will fit 5.45x39 and 5.56 NATO caliber AKs. Minor fitment may be required.

  • Replaces the gas tube and upper handguard
  • Picatinny rail for most optic mounts
  • Allows co-witnessing with iron sights
  • Lightweight and durable
  • Retains zero
  • Does not need to be removed for regular cleaning

This heavy duty mount replaces the original steel gas tube and upper handguard, so it adds less than one ounce to the weight of the rifle, making it by far the lightest optic mount installation for the Kalashnikov. The forward positioning of the optic gives you faster, easier and more natural targeting while maintaining your full field of view. Multiple target or moving target engagements, with both eyes open, become second nature. The UltiMAK AK optic mount rarely if ever needs to be removed to clean the rifle, so you need not worry about loss of zero. Since the mount is clamped to the barrel and not jammed in between the gas block and the sight block like the original gas tube, several UltiMAK users have reported an improvement in their AK's accuracy.

Awesome product and performs as advertised. Great quality and is complemented by add micro dot. Impressed by overall set up. Recommended !

Excellent aiming addition!


Everyone complained about co-witnessing an EOTech and such and the heat with this product... I love it, truly so. Amazing fit and finish and went right on with the UltimaK tri-rail. I have a 512 on it and it has worked perfectly from day one barely requiring any adjustment and has held zero through multiple bumps and whacks.Some people are concerned about barrel harmonics with this but honestly, of your trying to sharp shoot with an AK... Didn't effect my gun at all. Very happy with this product!Awesome product and lowest price found, will do business with these guys again happily.

Ultimak M1-B


Excellent option for mounting optics on AKM type rifles. Definitely allows for 1/3 co-witnessing for the Bushnell TRS-25.



havnt liked running a quad rail on my romanian ak74 so I thought I give in to the hype and try the ultimak. Paired it with my primary arms fixed base micro dot works great. Mounts super low, absolute co-witness. ultimak website said I was gonna need the shim set for my romanian 74 I did not. Barrel is tapered and where its mounts the barrel is large enough to mount without needing the shims.

Excellent company


I already wrote Marshall an email expressing how pleased I am with your company, but you guys rock and have some of the best customer service I have ever experienced (I am a customer service manager for Wyndham hotel gorup). That a long with your lightning fast shipping will have myself, and most likely anyone else who has dealt with you all, as life long customers for our firearms parts needs!



I got everything I needed and I got it fast. What more could you ask for.



I had conerns about this rail because this was my first AK. After fitting this with my Primary arms advanced red dot I am happier than a pig in $h!t. rail is amazing and will be ordering more primary arms advanced red dots for my other rifles.



I love you guys the shipping is always ridiculously fast!

Good looking mount


I never really liked the way the side mounts on AKs looked, so I searched for another option. The Ultimaks looked good and from what I gathered were decent mounts. Cowitness is no problem with a Bushnell TRS25. It wasn't too bad to install, didn't have to do any fitting on my WASR-10. I've taken it out to the range once and put just under 100 rounds through it. Half of those in a couple minutes and it didn't get as hot as I thought it would. If you do a couple mag dumps in a short period of time the mount might get pretty hot. Another thing is that it really doesn't add hardly any weight to the gun as advertised, which is always a plus.

Ultimak Fits Arsenal SGL 21 Well


I put one of these on a Draco pistol and it worked pretty well. Gives you a nice ridged rail on an AK.I liked it on the DRACO so I put one on my Arsenal SGL 21. Popped a Bushnell TRS-25 on the rail and ....BOOM, solid red-dot optic and mount. No weight gain. Good product.. Oh, slight complaint, Ultimak always makes the system a little short. Why not make it a little longer and design it so it can be modified by the installer for a tighter fit?

Solid platform and an attractive addition


I was a little unsure about how much room there is between the gas block and receiver when installing this one but UltiMAK clearly states this is intended. Once adjusted the mount is rock solid and allows for cowitness on your optic. Finish is matte and appears to be quality. I intend on a secondary review after range tests just to make sure the additional spacing will not be a factor.

A Quality Product


If you have aging eyes like me, this mount is the answer. This is a high quality product and provides a rock-solid mount for your optics.

Works great?


Instructions could be a little better, but not bad overall though. Does exactly what I need it to do. Sturdy, well crafted materials used. Weapon fires great with it affixed and I'm now able to hit targets up to 200 yards with a front mounted optic. (Saiga AK 74, 5.45x39)

Best AK mount out there!


I've searched for and tried a couple of different mounts for my AKs, but didn't like the limited options for positioning my red dots. Primary Arms had the best price so I bought one for each of my AKs. Well constructed, simple instructions, easy to mount. Took about 20 minutes on my first gun, 15 on the second. Can't be beat!!. Solid mount with no movement, stays dead on after multiple trips to range. Does not loosen up or lose zero like the cover mounted rails. The best option if you like your sight forward on your rifle so you have better field of view while shooting. Great product, shipped fast by PA. Thanks!

Smart employees and Excellent Service


Love shopping at Primary Arms



Ok, so I haven't installed it yet but i'm sure it's g2g. I've inspected it and it has flawless construction.All of that said I ordered this on Monday and had it by Wednesday night the SAME week. I didn't pay for any extravagant shipping but all the praise to Primary Arms is validated for sure.Gratefully,A returning customer

Great Service!


Order was exactly as specified and arrived when they said it would. Great prouduct, great service. Will definitely purchase through primary arms again.

Excellent service as always


Ordered the M1-B straight from Ulitmak before here, they took about a week to process and then they said my credit card didn't work. Got tired of waiting, ordered from Primary and the service and speed of shipping was amazing as always. Definately a go-to company for accessories



Primary arms always has quick shipping and great prices.I did have some difficulty putting it on an Arsenal SLR 101. The barrel is a little thicker than standard so the ultimak rings had to be 'massaged' to fit.

great product, great service


Primary arms you exceed all expectations, when I order anything its delivered promptly within 3 to 4 days. Keep up the great work.

3 point co-witness


Put this on the UltiMak gas tube rail. Allows for a perfect 3 point co-witness. Very stable, very nice.

Super mount!!!


Quick shipping, fit and finish are perfect. Sits low enough that with my comp2 I'm able to use the irons. This isn't the first thing I've gotten from Primary Arms and it won't be the last.

Great mount


Solid mount. Doesn't heat up as bad as I expected.

Great rail


This is a very good rail system. Very low profile and simple to install...with the exception of getting it to co-witness accurately with my Vortex SPARC. I found that to be very difficult as it never perfectly aligned.

Fits great on my SGL31 ak74


Well made and fits great. Installation was quite simple and painless as well after watching couple of YouTube videos.
