Umarex 110rd Magazine for H&K UMP Series Airsoft AEG Rifle (Package: Set of 5 Magazines)

"A qualidade do Mag é excepcional, faz a ump da Umarex funcionar perfeitamente, sem dar engasgos que data com od high cap de ABS que eu tinha. Unica coisa é o preço do dolar e o valor do frete, fora a chance de ser taxado, no meu caso foi, deu quase o preço do produto de imposto, 4 mags pra mim sairam quase mais de 1000 reais, foi uns 500 dos mags 200 do frete 500 de imposto, infelizmente a Evike é o unico lugar que vende esses Mags.

"I thought my ump had some feeding problems but thanks to this mag my ump was able to feed properly and perform very well on the field. I highly recommend this mag.

"I have 4 of these and they work great. They look great and have functioned properly for several weeks of playing.

"If you just bought the UMP45 by Umarex and having trouble to with hi-cap not feeding properly, BUY THESE MID-CAPS! It's awesome and no more shooting 3-4 rounds.

"These magazine are amazing! Very high quality polymer, sturdy as a rock. The mock bullets are a real nice touch. They fit and feed perfectly with my Elite Force Gen. II UMP.

"These are quality products and I highly recommend them over the cheap hicaps. The build quality is good and they don't feel flimsy.

"Love it!!!! It is a lot better than the High Caps...in everyway!

"These magazines are great! They're very well-built and fit nice and snug in my H&K UMP45 Elite Gen 2. My only issue is that they do not feed every bb. I have 5 of them and every mag leaves about 2-3 bb's behind. Other than that, they look great, feel great, and work great!

"Love these magazines! High-quality polymer and the dummy bullets give them a great look. I received a package of 5 and the only downside is that they don't feed all of the bb's, leaving 3-4 still. inside the mag. Overall, definitely recommend for any UMP user.

"This is a realy great mag. Made of high quality nylon fiber. The bullet window is only on one side. Wish it could be on both though. Only works on the Umarex/ Elite Force UMP. Tight fit and poor feeding on the Competition model I tried. Feeds perfectly in my 30rps UMP.

Pros
Feeds flawlessly.
High quality
Looks awesome

Cons
Base plate may come lose and require adhesive, this caused feeding issues for me for some reason.

"As of right now, i have had these mags for about 5 days and they feel great, look great, and preform decent... With the first 1/3 of the bb's in the mag, they all fire, then I get 2 shots and a dry fire, then the last 1/3 is completely random. Sometimes going 4-5 shots before a bb feeds. I have the elite ump that these go on, but they just don't feed great. The hi cap works pretty good, but I'm not a fan of tactical maracas. I will update this if anything changes.

"The polymer outer construction seems to be the same nylon-reinforced material that the Gen 2 Elite Force UMP uses, which is good. The .45 mock bullet window is super cool looking. In fact, everything on the outside of this magazine leads you to believe you're getting a quality product worth the asking price. However, almost everything on the inside contradicts this.

The problem is the way the guts are designed. It utilizes a double-stack design powered by a rectangular spring to achieve the theoretical "120 round" capacity. This tends to make BBs "lock up" whenever inevitable gaps occur during feeding particularly when it hits the single bend in the U-shaped channel. I understand why this was chosen since the magazine is quite wide and there is

But the main issue is the spring, it's confusingly undersized, not reaching or just barely reaching the end of travel so 1 or 2 BBs will not have spring pressure behind them. There seems to be several penny-pinching measures taken like this, for instance there is no spring guide to help the spring coil more evenly as it's loaded and no retention system even though there's plenty of space for one, the spring just sits against a flat internal wall in the channel. The rubberized follower is just a semi-circular nub with the end of the spring messily wrapped around it.

The only redeeming quality to the internals is that they are fairly easy to disassemble and reassemble for maintenance and I do appreciate the smart choices made for how the BB-stop housing is screwed in place separately from magazine body, makes it much easier to reassemble than usual for mid caps.

They're not "bad" magazines and while a double-feed system makes sense for a long, thickish magazine shape, it makes loading past 50% capacity crunchy, difficult, and a little unsettling. Maybe it'll get better as the magazine "breaks in" with actual use but I've had consistent jams occur while running ammo manually, even after lubricating the internals.
