Looking for what you guys think of the MDT mags. i have an MPA lite chassis and was looking to get some of the MDT 223 mags and wondered if they work well with that chassis or if you have issues. Also any experiences with the MDT mags would be great!
Thanks!
.223 mags are on back order right nowThanks for your interest AR.Bear15! All of our mags (barring our 3.560" LA magazines) are built to AICS pattern specifications and will fit any chassis/stock with that magwell inlet. I have personally seen our 223 and 308 mags run in almost every combination of stock/chassis/bottom metal out there, so I doubt you'd have any problemsIf you do, you can always contact us and we'll sort it right out.
308 is jumping out of the magazine?Does anyone else have a problem with the 308 MDT poly mags popping the first cartridge up out of battery. I'm only loading five rounds in the 8 round magazine. I wonder if it's a factor that I habitually insert the mag with the bolt back? Any ideas? It happens a lot.
FYI, this is with a Howa 1500 .308 and the MDT LSS chassis.

Hey there! It sounds like your mag may have slightly out of tolerance feedlips, which is causing your rounds to unexpectedly "jump". If you send a support ticket to our customer service reps at [email protected], I'm sure we'll be able to sort you out with a new mag or a better solution than what you have now!Yes. It pops up at a steep angle instead of toward the chamber. I have to pull the bolt back a bit, let the cartridge settle, then push it forward into the chamber. The rounds are seated to COAL of 2.8
I should hook up my phone on a tripod and do a video of it.
To be fair, I really should try inserting the magazine with the bolt closed to compare.
Oddest thing.

It's no worries! I am curious to hear more about the problem, because at the end of the day, we're all shooters too and want our products to be just as awesome as you guys want them to be!![]()
Josh;
I decided to test out my MDT polymer .308 magazines at home since the Howa 3 position safety allows for bolt operation. While pointing the rifle rest at a thick concrete wall, I cycled through all ten of my magazines with no problems. I even watched the close-up movie I made with my cell phone and watched all of the rounds sliding perfectly into battery.
The only possible cause I can image is the way I manually retrieve my fired cases from the action. This only happens at the range and is consistent. I imagine that I am somehow leaving the bolt partially forward when I remove the fired case. Apparently, it is forward just enough to begin feeding the round, but not square behind the case head, and manages to pop the next round upward.
I figured it was probably my fault and did not want to bother your tech support folks until I had a chance to explore further. I appear to be correct in that assumption.
All of my magazines appear to be of the same fine quality with the same tolerance on the feed lips.
Thanks again.
Thanks for the update @TXSGFmrCWO3 !I think after my last trip to the range, I figured out why I would sometimes have feeding problems with the first round up in my .308 MDT polymer magazines (10 round) in my MDT LSS chassis.
Being of the AR shooting tribe, I have a habit of slamming magazines home. Bad idea with the MDT polymer mags.
If you slap the mag into the DBM well, the top round is likely to pop up at least partially out of the feed lips. I don't believe it's a design problem, since the mags work just fine when their handled properly.
So, gently insert the mags. They very easily lock into the DBM.
Also, this is probably a non-issue on a closed bolt.

Hey Josh.
I am assembling a MPA competition chassis with a Rem 700 224 Valkyrie BA.
Will your MDT 224 modified mags work out?
Thanks!
Yes they'll work fine. These are the mags I used on my Valkyrie before I sold it.Hey Josh.
