Is the Classic Army UMC SMG Any Good?

One of the biggest questions we get asked is ‘is XYZ gun any good?’, and rightly so – our customers want to make sure they’re getting the best bang for their buck. With that in mind, over the next few months we’re going to be taking a look at some of the most popular searches on our website and asking the question – is it any good?


The UMP (Universale Maschinenpistole, German for “Universal Machine Pistol”) is a submachine gun developed and manufactured by Heckler & Koch. Heckler & Koch developed the UMP as a lighter and cheaper successor to the MP5, though both remain in production.

The UMP has been adopted for use by various countries including Brazil, Canada, and the United States. A small number of UMPs chambered in .45 ACP were officially purchased by the 5th Special Forces Group of the United States Army Special Forces, with some of the weapons seeing limited service in the early years of the Iraqi insurgency, making them among the small number of submachine guns deployed by the U.S. military in recent conflicts.


Classic Army is a manufacturer of airsoft replicas based in Hong Kong. It produces automatic electric guns or AEGs, and a small number of GBB (Gas Blowback) pistols. Designed to resemble real firearms, these replicas fire 6mm plastic BBs at safe velocities. Within the airsoft community, Classic Army is often abbreviated as simply “CA.”

Classic Army AEG’s are characterised by their many metal parts and realism, in that most parts that are metal on the real-steel counterpart are also metal on the replica (although they are usually not cross-compatible).


So, is the Classic Army UMC Airsoft Gun any good? In a word – yes. Personally, we’ve been a huge fan of the UMP as a real-world SMG, with it offering something a little different to the usual suspects you see such as the MP5, MP7 or AK74. In regard to Classic Army’s offering, you could definitely do a lot worse – in fact, we personally think you’ll struggle to do better, especially at an insanely competitive price-point of £229.99.

Classic Army have packed the UMC with a range of features that you wouldn’t generally see in an AEG of this price – taking note of previous complaints and rectifying them admirably. The V3 Gearbox included has seen a range of upgrades to battle against some problems the UMC had in the past – namely installing a reinforced spring guide and a reinforced piston head. Furthermore, they’ve reinforced the cocking handle; which can be locked and released for easy access to the hop-up. They have also reinforced the ABS body, receiver, grip and folding stock to ensure the UMC can handle any abuse you throw at it.

In regard to performance, the UMC performs admirably. Clocking in at IRO 330 FPS, the UMC is good to go out of the box with no real work needing doing to get the best from your potential new SMG. Ergonomically, the UMC is the perfect SMG for CQB environments due to its smaller size when compared to assault rifles.

One slight gripe in regard to the UMC is that magazines can often be hard to find. We do thankfully stock 470 round hi-caps, however, mid-caps can be a nightmare to find with various brands not fitting the Classic Army variant. Our advice would be to double-check compatibility first should you be someone who does not want to deal with the dreaded BB rattle from a hi-cap magazine.

Overall though you’ll be hard-pressed to find a better SMG at this price-point, and with that in mind the Classic Army UMC gets a great, big, fat stamp of approval from us!
