Cross Industries LAR15 mags woes and bankruptcy

[u/ssssssbob]

Just want to give everyone here a word of caution

I recently purchased a set of Crossmags for my rifle. Worked great until both my mags started cracking. Tried sending them an email with no response. Called the number on their website and it has been disconnected

Upon further lookup, turns out they went bankrupt a year ago

Cross Industries Ltd | MNP LTD

Just in case anyone wants to purchase their mags, don't expect to get any kind of help if they break

In the meantime, anyone have suggestions on mags for my CZ600 Trail?

Cross Industries have had issues with there mags and haven’t been able to find a remedy the entire time they were operating. With a bit of hard use the mags start cracking and breaking, and CI been blaming it on CLP and other gun oils. Which is not only a terrible excuse but really embarrassing. They were able to keep things under wraps by freely sending out mags to replace broken ones hassle free. I’ve had mine fully replaced 3 times, no business can operate under those stresses.

Solvents and other oils can be hell on polymers. They should have used a non-transparent glass reinforced polymer. That would have probably required some re-tooling which was maybe too expensive.

Yes I agree solvents and oils, but break free CLP which they blamed for my case is comparatively fairly gentle on polymer. Never had any issues even on clear ets, lancers, and translucent pmags

CLP can still harm plastics. Oils will penetrate into the plastic breaking down some of they polymer chains weaking it. Some polymers are better than others. Some oils are worst than others. I'm going to guess Cross mags used some blend of polycarbonate, which doesn't do great with hydrocarbons.

Interesting, great info. I’m farthest thing away from being an expert on polymer so I really have no idea on blend, just that they were the only mags having that issue. Also with my case and I’m assuming others since no one oil mags or mag well, the oil coming in contact is just through normal operation of the gun. It’s just seamed like a flawed product.

I think they used the wrong polymer when you consider it will be exposed to oils.

That being said, my mags don't get oily. But I've never run my 180 or AR wet.

Magazines are the most difficult part of a gun to design and make.
