a matt Posted August 31, 2019 Share Posted August 31, 2019 (edited) Any chance of you double checking those mags with your ammo in a friends open gun and and his in your gun?? But if a few MBX mags run then 1 would think it’s in the mags. Maybe measure the mags feed lips on the mag that function well, then compare the measurements to the others and all (140, 155 & 170’s) the MBX should measure darn close but If not get to wackin’ those feed lip closer or opening them to meet the good mags measurements. I’m not sure that pinching them with a vise is the answer for adjusting the lips. It might be the easiest way and maybe I need to try the vise next time, IDK. Mag lips do NOT bend very easily. I cover the feed lips with a cloth and measure a lot. . Sorry if this has been stated before in a earlier post but good luck and I’m sure you will get things rockin along soon. Always Optimistic!!!

Thank you Matt for those suggestions. Your suggestions are right in line with the magazine tuning videos I have been watching. I am taking a different route from MBX. I have purchased a couple of STI Magazines and the Dawson Magazine Tuning Kit. I am tired of relying on others to get my gun to work, even though I live not 15 minutes from Limcat. Being a Jeep owner, I have learned it is always best to fix your own things. I also understand that properly tuned STI Magazines are hard to beat for reliability. Whatever I get back from MBX, I will then just sell and switch over from MBX to STI. The hubris of the owner of MBX was too much for me to bear.

a matt Posted September 1, 2019 Share Posted September 1, 2019 Sounds good. I don’t blame you, it’s not like your paid or anything fir running the MBX mags. A little good customer service goes far in our small (by comparison) sport as will the bad. Good luck. Link to comment Share on other sites More sharing options...
