Great videos CP. Thanks for doing these.
One item to note -- the base plates look like they were designed to work with the AR15 version's mag couplers -- mako sells the 2 mag coupler and 5 mag coupler for reduced capacity mag states...
Well that makes more sense if the rail is used with a coupler. I was trying to think of a practical application for the rail.
Strangely enough, all the other reviews of these mags have all been positive. Search Youtube and you'll find them. Zahal has been commenting "great review" etc on these vlog posts, which one would surmise is driven primarily by profit motive associated with moving product out of inventory.
I like the Ultimag design and aesthetics, esp. the side window w/round count, but they are still:
- Not durable and plastic obviously fail locking lugs FAIL drop tests.
- I couldn't do the table top slam test since the 2 mags I has were already done for.
- Count as 3 - 922R foreign parts with a propriety base plate and follower design that cant be replaced with US parts to reduce the count. I have about 25 surplus mags converted to 1 - 922R count (mag body) by replacing follower and base plate.
- No more corrosion resistant than OEM surplus mags.
- More expensive than OEM surplus mags.
Good range/plinking mags, IMO, but I wouldn't stock up on them.
I was thinking about rebuilding/reinforcing the locking lugs off the future with a metal type epoxy (JB weld type) to see if that would work. Trivia.
I have a medium sized bin of OEM surplus mags, including a 10 pack or two still in original factory paper and plastic. These still appear to work well.
