ProMag AR15 Rollermag

ProMag debuted their new Rollermag at the 2015 SHOT Show. Their new 30 round Rollermags work with any AR15 pattern firearm and features four wheels on an anti-tilt follower. So instead of sliding up and down inside of the magazine it rolls, which Promag says reduces friction and helps the magazine operate more smoothly. They’re made here in the USA and will retail for $18.99 and should be released around March. Check out for more info.



The new PROMAG® RollerMag™ RM30 magazine reinvents
the wheel by adding them to their NEW friction-free, anti-tilt
follower. This revolutionary Rollerfollower™ creates a
smooth, rolling, controlled feed for maximum friction reduction
in the TECHNAPOLYMER™ magazine body. The guided,
anti-tilt follower rolls smoothly without contact to the
body, only the stop.

The new Rollermag™ RM30 for AR-15 pattern rifles will be
the first to be released this spring, with more models to follow
later this year. The Rollermag™ is made in the USA with
a lifetime warranty. PATENT PENDING.

    That’s clever! I wanna see how Magpul wants to sue them for patent violation, since Magpul thinks, they have the only right to bring polymere mags on the market. :-)))

    • J.T.

      Have you even seen the mags they were suing over? They were blatant copies of the patented parts of PMags. There are plenty of other polymer mags out there that haven’t infringed on Magpul’s patents and didn’t get sued.

  • M.M.D.C.

    ” The new PROMAG® RollerMag™ RM30 magazine reinvents the wheel…”

    This was my first thought.

    Also, don’t more moving parts provide more opportunity for failure?

    • noob

      depends on how slippery the plastic is that they make the wheels and follower out of.

      say that some awful gunk gets inside your magazine and makes the wheels stop turning. maybe if the polymer itself is slippery enough you could smack the magazine against a rock and the follower might still act as a follower if the wheels just slide up the inside of the magazine without turning.

      • BryanS

        Any amount of crud that would do this would foul up just about any magazine.

      • Danny

        I assume they would just act like follower legs if they got gunked

  • Jon in NH

    Lets take the part of a firearm most prone to failure and add more moving parts for added failure. Brilliant! ProMag really is on the cutting edge of mag failure.

    • Bill

      Pretty much where they’ve always been, isn’t it? And for a higher price than the proven PMags, Lancers, etc….

      It might just work, but their quality control is going to have to be out of sight. A bad batch of magic plastic formula, wheels break, mags act up and game over, man.

      • AJ187

        I’ve owned plenty of pro mags across a lot of platforms that have worked. Guess, people will just have to try them for themselves though.

        • Ethan

          I’ve tried a number of their pistol and rifle mags, and my personal experience has been that they’re pretty awful. YMMV

          • MikeK

            The only way I can make my HK USP jam is to run a P-mag in it! It shames me that they are an American company, I guess on the same breath so is Red Jacket!

          • balaclava

            Pmag or Promag?

          • Jeff Smith

            I had the same experience with my USP 45 and a Pro Mag.

        • 2wheels

          The ProMags I’ve used generally work ok for range fodder, but I wouldn’t trust them for a carry/defensive gun.

  • Asdf

    looks like they took a hint from the Sterling.

    • Tom

      I wondered if anyone was going to point that out.

    • noguncontrol

      exactly, which is still considered the best most reliable 9mm magazine in existence, if it worked for the sterling, it could work here, the problem with the sterling was it was too expensive, too overengineered, if Promag did this right, without the expense, they have a winner here.

    • Anon. E Maus

      Not -quite-, the Sterling magazines had rollers on the follower, but they didn’t sit on the side of the follower to ride against the magazine walls, they sat the same direction as the cartridges, I think the idea being that it would be easier to load cartridges into the magazine as there would be less resistance. Google up an image of a Sterling mag to see what I mean.

  • gunslinger

    lets get some dust/dirt in those wheels

  • JumpIf NotZero

    Well, I suppose if you are dumb enough to buy Promag products, the wheels inside the mag probably seem like a good idea.

    • Taktikill Macho Man 9000

      It’s hard for you to make friends, isn’t it? 🙂

      • JumpIf NotZero

        To be fair, I would have a hard time making friends with the type of people that bargin hunt gun parts. So, yes and no.

        • Grindstone50k

          Because inexpensive automatically means low quality…

    • Nicks87

      The local sporting goods store was selling Promag AR15 mags for 5 dollars a piece! I’m a cheap SOB but I still wouldnt pay $5 for one.

      • JumpIf NotZero

        By spending $5, someone is likely costing themselves more than that in time and by throwing that $5 away because no one wants to buy one.

        “I’m don’t have enough money to be cheap.”

      • Anon. E Maus

        Should have snatched one up, they’re trash, but that’s the fine part, you can use a ProMag to do failure drills, how to clear malfunctions and misfeeds.

  • Francis

    I’m going to spare the teeth-gnashing and test one of these mags for myself. Some of you guys are a little too defensive of any interlopers in the polymer mag field.

    • JumpIf NotZero

      Comment might be valid if every Promag magazine for every gun ever made wasn’t sub-par to the OE magazines.

  • PeterK

    More stuff to fail? Meh…

    • Joshua

      Depends, the Sterling magazine was probably the most reliable magazine ever invented, and it used rollers.

  • Laserbait

    Interesting. I am pretty happy with my PMags, and have yet to have a failure with them, so I’m not keen to replace them all. I might have to to try a couple though just for fun.

    • Cymond

      PMags are not the same as Pro-Mags.

  • matt RRC

    Looks like a 5.45x39mm test to me.

  • kgallerno

    This mag is a answer to a question, no one ever asked.

  • Franklin

    Even if the wheels were to get gunked up to the point they stop rolling I doubt the magazine would fail. The spring tension would easily over come then friction. Looking at the follower I don’t see how fouling would possiblly be detrimental.

    As far as any benefit from the system, I’m not seeing it.

  • Brett

    Why does every polymer mag have that ridiculous hump of a plate at the bottom?

    • Hunter

      needs a bit more “meat” so it doesn’t break vs. aluminum or steel mags which are much stronger.

  • Rog Uinta

    Wheels? There isn’t anything ProMag could add to one of their products that would convince me to buy one. Fool me once…

  • Randy

    Did anyone else notice the op is shouldering the Sig Brace?!? Guess they didn’t get the memo.

    • David Sharpe

      The video could have been shot before the “ban” on shouldering the Sig brace.

  • G I

    How is ProMag still in business?

    • Scott P

      Idiots, gun noobs, those who rarely shoot their guns, those who use them as training mags.

  • Jeff

    My guess is this is really just a proactive move to avoid any problems with MAGPUL’s patent suits against companies with anything too similar to its anti-tilt followers.

  • Joshua

    Generally I avoid the company like the plague. But give the history of the only roller mag I have ever seen(Sterling mags) I may just have to get one and run the piss out of it.

    Plan on doing lots of sand tests as well. I mean what can one mag hurt.

    • Terry

      If you do a test, make sure it’s over 200 rounds. Jumplf is pretty specific on this–you must shoot over 200 rounds. 😉

      • Joshua

        I plan to fill it with sand, mud, water, etc. Whatever I can get my hand on. I’ll also bring 300 rounds and only use the one mag.

  • Squirreltakular

    I don’t see a point to the wheels, but…

    Everyone seems to be liking all the Archangel stocks and whatnot. Maybe this line is just higher-end? Like the Acura to Promag’s Honda?

  • MadMonkey

    Another perfect example of a solution to a non-existent problem.

  • MrApple

    I find it interesting that so many people are dumping on Promag (not my favorite either) for this new idea. I wonder how many would be chomping at the bit to buy one if Magpul came out with the exact same idea.

  • BuzzKillington

    The saying, “If it isn’t broke, don’t fix it,” applies to this ‘solution’ to a nonexistent problem. Anti-tilt followers fixed an issue with binding. Now, with followers like Magpul’s, my magazines run extremely smooth. Adding wheels that are bound to freeze up from dirt and debris, while also reducing the clearance for the follower to pass over said debris, which may be coating the inside of the magazine body, is a recipe for failure.

    • noguncontrol

      it worked very well with the sterling smg.

      • Matt Shermer

        The Sterling needed the help of a roller-aided follower. The Sten magazine was developed without one, and you get some really weird physics when you have a horizontal feeding system, which led to feeding issues (another reason British Commandos preferred the Thompson M1 when they could get it). The Sterling magazine included that to combat the feeding issues inherent to a horizontal mag.

  • Tucson_Jim

    There are a ton of dry-film lubricants which will make a magazine virtually trouble-free… Teflon mold release agent works fine, I’ve not even had problems with WD-40 (my usual lube) if it’s allowed to dry for a couple days before loading… silicons and transmission fluids are a problem, though, because they creep across surfaces and will migrate into cartridges, causing ignition failures.
