Seems like a lot of mixed results with the NATs carts.

I've been using them for a month or more with zero problems. The guys from nats respond to any question or comment you might have (I get direct messages asking how I like the needles and if i would change anything... nice guys, and respond within minutes). And I got my package within days of ordering.

The liners I like more than cheyenne or ttech. The mags are nice, but I think I like ttech more. Just trying to decide how much more I like the ttechs, and if I would rather just save a couple bucks and get the nats as they work fine as well.

Haven't had any jam or any problems with the rubber band inside (though it's good to know the dental ligature tip).
