If that CSA mag is truly made of polycarbonate I would not buy it. That mag does not compete with ours so I feel alright about posting this with no bias. I can tell you after spending a year and a half researching material for mags that PC is not a good material for a magazine.
The benefits of PC are that it's cheap, clear, and very impact resistant when it starts it life. However, the material quickly loses it elasticity and becomes brittle and prone to cracking, epically when exposed to UV rays. Also, PC does very poorly in creep testing, so that would not be good for feed lips. I really don't know if that mag is made from PC, I'm just going off what the video said. I tried to search t Google and find more info on those mags and I couldn't. Just wanted to share some scientific info on polycarbonate and why it's not a good material for magazines. |

Yeah, I couldn't find out very much about these either. It seems like they don't sell the mags on their website, and they don't list their dealers either. I've never even heard of this company before today, and I was curious if anyone else knew anything about them.

I've never even heard of this company before today, and I was curious if anyone else knew anything about them. Here is the info on the mag taken for the Czechpoint USA website "Manufactured by Czech Small Arms and is the second generation magazine possessing a waffle type pattern (waffle pattern increases resistance to crushing weight and enables better gripping). All parts are made in the Czech Republic. The 5.56x45mm 30 round magazine fits and functions with double stack magazine vz.58 5.56x45mm rifles and the vz.58 5.56x45mm pistol. The magazine is made of semi transparent polycarbonate, TARFLON IR2500, while the floor plate and follower material is Zytel ST801." Here is the link to the mags in question: CSA Gen 2 Magazine |

$24.50 / 1 pc
 That's $10 too high.

Apples and oranges -Different weapon platform equals different geometry, wall thickness, etc.
That said it is significant they used the M2 magazine and not the Gen M3 which can survive a 6 foot drop without damage...

This is absolutely true! I would dare to say this comparison is more about them saying their product is as good or maybe even better than the MOE Gen2 PMAG, which is held in a high regard. So, in proving that they can beat out a MOE Gen2 in a drop test, people can also hold their mag to a similar level when it comes to durability. Magpul has a great rep and there should be nothing more flattering than the competitors using your mags a the gold standard to compare their products too! |

Get with the times.....A 20 ft. drop is the new standard. I thought the USGI magazine designed 50 years ago was the standard??? I personally think that any mag comparison test should be against the the Lancer which is without question the most unbreakable mag out there. |

I think it's good to know that we have hit a point where the spring is now the weakest link in the magazine. Because good springs last a long time and are cheaply and easily replaced.

This post seems reasonable. I have a shop with many plastic bins. All the clear ones now have cracks. Few years back .223 AK mags from Bulgaria had some similar issue. |
