CQB Master Full Metal 49rd Magazine w/ Spacer for KWA Kriss Vector Airsoft GBB SMG

"They are just as good as the OEM in view, I currently have 6 of them and work great!

"Got mine three weeks ago and they work as expected.

"Some good, some bad - 4.5/5

We all know how rare vector mags have become and how expensive they can be, so before you buy these, allow me to give an honest opinion on them.

Pros:
+ At $36, these are CHEAP
+ They resemble the factory mags very closely
+ They have similar gas efficiency and fps output to the KWA mags
+ Metal and weigh the same as the KWA mags
+ No fit issues and they don't wobble in the magwell.
+ Able to easily fill the mag with the base plate on (same for KWA mags)

Cons:
- Only comes in black
- Feed nipple required a 'break in' period before it would feed properly (on 3/4 of my mags) a light sanding with very fine sandpaper or a file seems to help negate this (not all mags will need this)
- Noticeably cheaper construction and lacks trademarks, although it does have the RS .45 caliber engraved on the back of the plastic shroud
- Fill valves in all of the mags did not have o-rings installed to prevent fill leaks. Get some o-rings!
- Base plate can crack with hard bumps
- Valves and o-rings needed lubrication. 2 of my 4 mags leaked out of the box until i lubricated the valves (both fill valves)
- These mags are MASSIVE (as are all vector mags in general) although i'm able to squeeze 6 of these things into a double AK mag pouch - Two at the back of each pocket side by side and one at the front, feed lip down.
- REALLY HEAVY. You are going to want proper storage for vector mags - they are about 1lb each and a bunch of them can easily weigh you down. Spread the weight and find proper pouches.

Most of the cons will make sense if you already own a KWA Vector

The cons seem to outweigh the positives, but after some break-in and TLC, these mags are your best bet for the vector. if you own a vector, these are a must-have! these mags are affordable enough to buy multiples, and with Evike being a US based retailer, these arrive weeks ahead of mags from Hong Kong suppliers. With these, you can actually build a vector load out worth using.

"So after much debating I decided to purchase these magazines. They ARE CHEAPER in material and production than the KWA mags. There are plenty of visible seams and the plastic shield is alot flimsier than the KWA one. Also my mags didnt ship with fill valve oring seals. This is my biggest issue. They work and perform well, however cosmetically they do fall short.

"Kinda disappointed with this. I only ordered one, as it was all needed at the time. Out of the box, it feeds BBs just fine, and sits in the magazine well securely, but it is DEFINITELY lower quality plastic than original KWA mags. Just by applying force the wrong with my hand I cracked the baseplate. I can only get half of a mag out on what I thought was a complete fill of green gas, so I guess I need to look into o-rings or just replace the whole fill valve. Overall, I'd hoped for a little bit better, and now that the price has risen, I'm even less certain I want to buy more...

"Before I start, I would like to note that these mags are not CQB Master. They are Matrix.

I ordered two, and while the build and plastic quality is rather nice, they both will not function.
One cannot hold any gas, and leaks out of the nozzle seal.
The other holds gas but just doesn't release gas when the trigger is pulled.

Unless I get approved for getting the mags fixed/replaced and the new ones work properly, I would not recommend these mags at all.
