The M2-B has a Picatinny rail 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 (we recommend our MD-FBGII).

Note: For AKs that originally used gas tubes that have holes in them, such as the Chinese MAK-90. 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 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.

Color doesn't match well but functionally sound

Utimak rail.


Decided to make the drive to meet some PA guys in person and just like online, I enjoyed great friendly service. The Ultimak is a great addition, a rock solid mount, can highly recommend it and Primary Arms



Easy to install. Great with PA MD-RGBIII. Can't wait to get to range & test its durability.

Fast shipping. Great product!

Solid rail


I placed this on my DDI AK47U and its works just as stated it would. The ultimak is easy to install and it is very solid. It gets hot but by now everyone knows how the ultimak rails are, they just work.

Consideration for 5.56/.223 users


I put this on on my Arsenal 106Fr 5.56 w/ Primary Arms Micro Dot, and Troy Battle Rail. Everything works smoothly. I had to take my rifle and parts to a smith cause the U-clamps where known to have fitment issues with the Troy Rail( I don't have dremels or grinders)plus my SRVV Jet Brake had to be machined also. But the reason why I went with this particular mount is because I didn't want to over pressure my receiver with the hotter load(pressure) of the 5.56x45 than that of the 7.62x39 counter part.
