Plate Design ACEM Magazine Loaders

I really don’t mind loading mags – that is when I’m blessed with plenty of advance warning to do so at my leisure. For those more ‘immediate’ needs, I currently prefer to use a Mag-LULA that travels in my ammo bag. However, after stumbling upon the speed loader products from Plate Design, l may have a new option to try out.

The new ACEM Gen 4 Multicaliber loader can quickly fill AR magazines from a variety of different calibers – from the standard 5.56 and .300BLK to 7.62×39 and 5.45×39. From the Plate Design videos, the loaders seem to be very well made as well as easy to use.

They also make a variety of other models to fit magazines from several different platforms.

Thanks to its patent pending design, the ACEM can load live, blank, training and irregularly shaped rounds (if using 300 Blackout, 5.56/.223, 6.5 Grendel or 5.45×39, only live rounds). With its two piece polymer construction, the ACEM is both extremely durable and easy to use. Load 30 rounds at a time effortlessly with the push of a finger, with the aid of an additional mag or with the removable push-assist. Best of all, the loader was designed to load virtually any magazine, even drum designs and high capacity models, all without damaging feed lips, projectiles and, most importantly, your fingers.

In developing the ACEM, we consulted with both active and retired specialized military personnel, law enforcement officers and shooting enthusiasts to provide the best loader possible. To ensure its durability, the ACEM AR/M4 30 MC Gen 4 was subjected to extreme temperature, impact and chemical tests. The ACEM AR/M4 30 MC Gen 4 was also tested with every magazine and round we could get our hands on, so if you find a magazine that doesn’t work with your ACEM, we want to hear about it!

    Looks like a solid peace of kit. Maglula is grossly overpriced and I prefer to buy American whenever possible.

  • BattleshipGrey

    Not to take away from this product, but there’s some great homemade designs as well if you like DIY projects. Google and Youtube have some great examples.

    I’ve never messed around with mag loaders (other than military stripper clips), and thus, am not familiar with their ease of use. Do you have to load them one-by-one just like a magazine without a spring? If so, what’s the point (as far as saving time)?

    • Xtorin O’hern

      if you align them right you can sorta just sweep them in 5 or 6 at a time, its much faster then loading the mags by hand, but i feel as though military stripper clips would probably be faster

      I don’t like 5.56 strippers. They tend to bind up and make it impossible to feed

    • john huscio

      Striplula works like a charm.

  • thedonn007

    This is good and bad. It will allow me to burn through my ammo that much faster.

  • Jeff Smith

    I never minded loading mags, right up until I took my brother and about seven of his friends shooting for the first time. I loaded all of the mags for probably 1,000-1,500 rounds. Loading surplus AK mags will cut your finger open eventually.

  • rjackparis

    still doesn’t seem as fast as a mag charger,

    also much more compact.
