Question: Is it metal or plastic?
Document: Mag fits perfectly on my m416' there is currently no problems I have to face, except he fact that I have to pull out my mag. It's because it made out of strong plastic unlike other metal based mags, which can smooth itself out he gun without having to deal with taking out the mag itself.
Not bad, there plastic but they have good weight to them and seem pretty well made. worth the buy !
To start off I live on the east coast and these were shipped from California and it got here in 2 days!Now about the mags, I want to let you know I am very strict about having all metal everything when it comes to airsoft. The picture of these mags caught my eye though they have a very cool and uniqe design.
The plastic is very strong they are thick nothing loose feeds great and they are very high quality.If your thinking about these mags I highly suggest you buy them. Hope this reveiw helped you guys out, good look out there!! !
First off, these mags are very well built. The plastic feels like it can take a beating. I was kicking them around the field and they seemed to do alright.HOWEVER, some feeding issues did arise with use:1. Firing on full auto would lead to misfeeds, which is weird because my gun doesn't have a crazy ROF (only ~16RPS).
Just a heads up, depending on the seller you choose to buy from, the mags will not come in orginal box but come loose in a USPS envelope. My package was delayed like one of the other review because it was damaged along the way. Most likely due to how they packaged the mags. The envelope was torn up but luckily none if the mags were damaged. USPS packaged it in a plastic bag to prevent the mags from falling out with a message saying it was damaged.
cheers
after using them for about 2 full games (Saturday 8hours and Sunday 8hours) i can see why so many like the design as will as the grip you get. not only with your bare hands but also feel great with gloves. over all great product there is a small problem that truly bugs me. and that is the spring is very weak after 2 full games i notes the springs on 3 of my mags became weaker.
Work fell, feed well. LIghtweight yet comfortable to hold. Resembles a Magpul Pmag without the shiny price tag. Would recommend
