|This is a fun toy, and worth getting if it's on sale for around $80. Not nearly reliable enough for any use other than as a range toy. Mine fed the first 100 FMJs with only 1 or 2 failure to feeds. The next 100 were hollow points, which resulted many jams/failure to feeds, I stopped counting after around 10, but it trailed off towards the end of the mag. Come to find that the hollow points gouged out the front wall of the mag body. After that the next 100 rounds of hollow point cycled without issue.
While the springs may be able to hold up to being stored loaded indefinitely, I highly doubt that the feed lips will not deform due to "material creep" (Google it).
So if you can get it cheap, its worth having as a range toy. If you can get it for half the cost of the other beta mags on the market, then my opinion is that you are not wasting your money.
I know that I will be buying a better quality one for SHTF situations, but I do not regret buying this one considering the cost/fun ratio.|
