Gear Review: IK-520 40 Round Magazines

A great offering from MWG is their IK-520 40 round magazines. The mags are imported from Bulgaria and cost the same as a 40 round Magpul magazine. From MWG’s website:

  • Designed by renowned development engineer Ivan Kolev, designer of the Bulgarian high capacity polymer AK Magazine.
  • Increased Capacity
  • Durable, Steel Reinforced Polymer Construction
  • Ergonomic Waffle Design
  • Stable, Level Follower
  • Lightweight:  .4 Lbs
  • Tested full and semi auto in M4, AR-15, M16A1, M16A2 Models
  • .223 Caliber, 5.56mm

So how do they work? Well first off I wanted to see if they locked in and fit in my SCAR, a gun well known for being picky with magazines. Some mags have a tendency to raise the bolt catch just a tad that results in damage to the firearm. The IK-520 mags locked in without raising the bolt catch:


My friend Patrick and I took them to the range to see if they performed well and they worked great!


His M4 pattern rifle digested all 40 rounds with ease, regardless of how fast he pulled the trigger. The bolt locked open and they performed perfectly.

A few days later I did a few drop tests with no noticeable damage to the feed lips or expulsion of ammo from the body, so I suppose the steel reinforced lips helped in this regard.

Lastly, I decided to put my Wrangler against a mag:


As you can see the mag didn’t buckle or come out to bruised:


The mag still loaded all 40 rounds fine and there was no difference when locking the mag in.

So these are a great alternative to a PMAG and are priced the same, but for $18.95 most shooters will opt to buy the familiar Magpul brand mags.

    Yeah, being at the same price point as the magpul mags… I don’t see the point of importing them for sale at this time. The 40 rounders are readily available online. A year ago this would have been amazing!

    • iksnilol

      They are metal reinforced unlike the Magpuls.

      • G Stacks

        But does that even matter? Pmags have been proven reliable, and have undergone equally as rigorous, if not more, testing than these.

        • iksnilol

          Better safe than sorry, I don’t want to end up in a situation where my mag lips get split or ruined.

          • ColaBox

            Does that happen often to you? What kind of shooting do you do?

          • iksnilol

            Doesn’t happen often but with my luck it probably would.

          • I’ve had two PMags split at the rear of the feed lips.

      • zardinuk

        Something to gather rust.

  • noguncontrol

    the more the better.

  • YesMan

    Magpul doesn’t have metal reinforcements unlike this magazine. For anyone that is hard on their gear, this is a must.

  • Trey

    DS Arms has a smooth sided version of this mag that is also from Bulgaria, and by the looks of it the top part of the magazine appears the same. I bought one two years or more ago, but have never tried to use it.

    Now if someone would make a plastic version of this:
    That would be sweet…

  • otto

    another 40 round JamMaster for the AR platform

  • Dan

    Its kinda of like a 40 round lancer awg. Metal reinforced are superior. One benefit is metal to metal contact at the mag catch. Mark my words you will see a Gen 4 or 5 metal reinforced PMAG.

    Would’ve been better if this was designed for the slr106……there are already craploads of mags for ARs all over the place….
