Page 2 of 6 - Umarex Legends MP40 BB Magazine .177 (4.5mm) Cal Reviews

Having s spare magazine for my umarex automatic bb rifle

I do not see any thing to change

Should buy a spare magazine

being able to hold 52 rounds is awesome. The spring lever is easy to push with your finger and it has a notch to hold it open while loading

nothing

you will get the best performance out of these mags with Umarex CO2's

This new version of the mag has a notch to hold the spring back when loading. Simple yet ingenious. So much easier to load than the original.

Lower price would help me buy several more.

You will not regret buying this mag. You wont want to use the original mags ever again.

Best pricing on the WWW, and prompt shipping!

You can't find a better retailer, wish they had local store here!

I really like my MP-40. Having 3 magazines to load all at once allows the CO2 to warm up a bit between reloads so I get a little better performance. I definitely recommend having more than one mag.

A notch to lock back the follower would make reloading MUCH easier.

Put a drop of oil on a Q-Tip, pull back the follower and put the swab in the BB track. Run the swab along the inside of the track to LIGHTLY oil it and it seems to help the BBs feed more reliably. DO NOT over oil it or it will gum things up.

The magazine was a pleasant surprise in that it functions much better than the original magazine that came with the MP40. There were no jams or malfunctions when using Umarex Black Diamond BB's. At 80 degrees F, mixing full and semi-auto, the CO2 cartridges lasted slightly over 200 shots. That was more than the original magazine delivered. I did mix a half dozen Daisy silver BB's in one magazine load to see if they would mis-feed as they did in the original magazine; there were no problems. The mag is pricey, but works well and makes the MP40 even more enjoyable.

It would be very easy to modify the magazine so the follower could be held back by inserting a pin or to supply a wire catch. I made a catch from a piece of coat hanger that holds the follower while the mag is being loaded. Although not part of the magazine, Umarex should have an available cap for the Black Diamond BB's that would allow them to be poured into the magazine opening. That would be a very simple "fix" to make loading the magazines easier. One can probably be rigged up from a plastic ketchup container top.

I sprayed dry lube into the BB stack of the loaded magazine and that may have helped the performance of the magazine. Loading carefully, it is possible to rock the mag back and forth so the BB's do stagger. As the CO2 cylinders near the end of the charge, the bolt has to be manually cocked for the last dozen shots - not a big deal.
The MP40 is amazingly accurate and a lot of fun to shoot!

i had to get a replacement as my original was damaged by fouled bbs. Wirks great! Only use quailty bbs, no copper that corrode.

Thanks for quick shipping, these were a gift for my wife who's only complaint was it took so long to reload. After 1day she had made her own speedloaders out of drinking straws, a loading tool that holds the spring back(coat hanger) and a clearing/ cleaning rod (welding rod). She mastered the trick of staggering BBs in no time. With the extra mags it just adds to an already super fun gun.

Perhaps a free fix (3D printed) for the failure of piercing both CO2? Extra hex wrench maybe?

The fun factor is off the charts. Stock up on CO2 and BBs.

These were a gift for my wife. She purchased the mp-40 and her only complaint was she couldn't reload fast enough. Since then she has fabbed up her own speedloaders and a mag spring holder that cut down on the reload time.

Mag loading double stack style takes a minute to adjust to but if it works don't fix it.

Be prepared to have sore face muscles from the constant grin. Oh and stock up on C02.

Capacity

Needs a way to lock the spring when loading BBs.

Seems to need frequent oiling to keep from jamming up and not firing.
