BallisticianX Posted June 21, 2016 Share Posted June 21, 2016 In preparation of receiving my new Bedell 38 SC (to retire my Tanfo gold team in 9mm) I got some MBX 140 mags. The MBX followers are odd. At first glance they look like a phenolic material, like green bakelite. But it appears they are some kind plastic composite. I guess its the non-traditional look and the rough texture that makes me wonder if they work. I used Grams in my Tanfo mags and they were flawless, not one feeding problem in 6000 rounds. Of course I dont have the gun yet to test these MBX followers in order to confirm or discredit my doubts. I just want to have the mags setup right before hand to prevent solving possible issues later on. So what are your thoughts here, MBX worth keeping or am I better off with Grams or am I good to go with either of them. Thoughts? Link to comment Share on other sites More sharing options...
Maximis228 Posted June 21, 2016 Share Posted June 21, 2016 Ive been running complete MBX mags for 9 major for about a 1.5 years now. They are for real! 75K+ down the pipe with these things. 30+1 for all my 170s right out of the bag. 24+1 with my 140s. Their follower looks to be 3D printed.

Deerhunter9790 Posted June 21, 2016 Share Posted June 21, 2016 I have run nothing but MBX in my 2011 and they have run phenomenally. No complaints and I would let the look discourage you. Link to comment Share on other sites More sharing options...
Rowdy1111 Posted June 21, 2016 Share Posted June 21, 2016 Love the MBX mags my 140s and my 170s are awesome and haven't let me down Link to comment Share on other sites More sharing options...
theWacoKid Posted June 21, 2016 Share Posted June 21, 2016 They are 3d printed I believe. Seems to turn a lot of people off for some reason. However, just like everyone else I'm running 6 of their mags just like they come stock and they've been flawless. Link to comment Share on other sites More sharing options...
MrPostman Posted June 21, 2016 Share Posted June 21, 2016 Yep MBX all the way! I use one 170mm and two 155mm mags for my open rig. Not one single magazine related problem since I bought these. Link to comment Share on other sites More sharing options...

Springs have to change at about 15,000 but thats it. Try them, I love mine! I'm about to sell all my sti and svi mags and get all mbx's. Link to comment Share on other sites More sharing options...

zzt Posted June 22, 2016 Share Posted June 22, 2016 All of my MBX mags work well with both the green non-lock back followers and the larger grey lock back followers. One of the things I like about the green follower is you do not have to modify it in any way to prevent slide lock. It will not hold the slide open even if you have an unmodified slide stop. That is a big plus for me, because some matches require slide lock. I don't want to change slide stops, so all I have to do is swap out the springs and followers to change back and forth. Grams followers in my STI mag and Taran Tactical followers in my Infinity mag will both lock the slide back with one round in the mag unless you alter the followers.

Foxbat Posted June 24, 2016 Share Posted June 24, 2016 They are OK, but according to many (myself included) they are 29 rounders, not 30. Perhaps there have been different lots, I don't know, but some people had less luck than others. Link to comment Share on other sites More sharing options...
mwray Posted June 24, 2016 Share Posted June 24, 2016 I'm on the less luck list but after swapping to all Taran guts they have been wonderful Sent from my iPad using Tapatalk Link to comment Share on other sites More sharing options...
Edge40 Posted June 24, 2016 Share Posted June 24, 2016 Totally happy with them as they come. I know plenty of guys that use them stock with zero issues. Link to comment Share on other sites More sharing options...
SSGJohnV Posted June 24, 2016 Share Posted June 24, 2016 All stock, zero issues. 30 rounds of 9 major in the 170, 29 reloadable. 24 in the 140, 23 reloadable. Some people claim the big stick is a 29 rounder, but I've proven 2 people wrong by using an UPLULA. You have to cram it in there. I go 30+1 at every major, zero issues. Adrian stands behind his product as well. Link to comment Share on other sites More sharing options...

tyler2you Posted June 24, 2016 Share Posted June 24, 2016 If you are able to get 30 rounds in your MBX big stick, make sure you don't have to use excessive force to get it to lock in with a polymer grip. I cracked one at the mag release after just a few matches of whacking the bottom of the mag to get it to lock in the gun. Link to comment Share on other sites More sharing options...
teros135 Posted June 24, 2016 Share Posted June 24, 2016 but I've proven 2 people wrong by using an UPLULA. Like WOW! Something new every day! Yeah, I can us a Uplula to CRAM 29 in my MBX 170 (with stock internals), but it's not loadable and stresses the grip. With TTI internals I can get 29 in by hand (reloadable), but it still won't do 30. Same for my MBX 140, which take 23 but not 24, no matter what. They're actually somewhat variable, one to another. Just because you have one than can doesn't mean that everybody has the same thing. (And yes, I'm pretty sure I know how to use a Uplula loader, and I've seen the MBX video.)

Foxbat Posted June 24, 2016 Share Posted June 24, 2016 I have two 170's, purchased some months apart, and I can jam 30 into one - but would not do that in a match. The other one - no way Jose, 29 is all it accepts. Which is perfectly fine with me, I really don't see any advantage in asking for potential problem for the sake of being able to tell people you can start with 31. I start COMFORTABLY with 30 using either the SVI mags, or the MBX's - so I perhaps overpaid for the MBX's slightly, but no big deal, I like trying new things.

teros135 Posted June 24, 2016 Share Posted June 24, 2016 Well, to add on to my earlier comments, my MBX mags work reliably in my Open gun, for both .38SC and 9major. My STI mags (TTI or Gram internals, TTI base pads) are okay for the 140s and not reliable for the 170, and not at all reliable for 9major, no matter what I do to them. I need to get a couple more MBXs, for that reason. It's probably just my gun; no two act the same. Link to comment Share on other sites More sharing options...
SSGJohnV Posted June 24, 2016 Share Posted June 24, 2016 I also use a CK metal grip, so less worries about cracking a grip. Just anecdotal evidence on my part regarding the 30 capacity. Might want to ask Adrian about it. Link to comment Share on other sites More sharing options...
Foxbat Posted June 24, 2016 Share Posted June 24, 2016 I have SVI stainless grips, but I do not like applying too much force - something is going to break at some point. If it takes more than just a gentle push, then I can do without it. Link to comment Share on other sites More sharing options...
BallisticianX Posted June 24, 2016 Author Share Posted June 24, 2016 Good info coming from you guys. Thanks. I havent tried to load up my mags to there capacity yet. But I never force anything in either a mag or the gun. Everything needs to be smooth and almost effortless or it creates problems. As the old saying goes "things in life are like a fart, if you force it you end up with shit!" Link to comment Share on other sites More sharing options...
warpspeed Posted June 24, 2016 Share Posted June 24, 2016 The 170 MBX I have is no better than a STI tube with Grams internals & spacer. Both work just fine but the UPLULA is mandatory to get them full. Link to comment Share on other sites More sharing options...
