MPX TF magazine extensions

I have seen conflicting reports of how these perform with the factory 30 round springs. Some say you need extra power springs and some say you don’t. What say you?

they will work with stock springs, they just don't lock the bolt back reliably, so I put the extra power springs  to fix that problem. Only really was a problem when shooting IDPA stages with mag round limits, never a problem in USPSA

MPX, go with Taran pads.  I have a TF for my Colt style mag, not worth a dime. Changed the spring, still no luck. Put it back to factory, works great.  I have a Brian Miller for the Colt and it is great.  MPX, pull the base pad off and put on the Taran and shoot a match with out a worry.  Save your money on the TF.  Wish I could get my money back.

I have the TF +10s. They need an extra-power spring to lock back on last round. So I bought a bunch for all my mags. 

Unfortunately, with these new springs, I can only get 36 rounds.

 

Those 36 were super tight in there too, so I ended up downloading to 34 out of concern they’d cause a feed issue. Very disappointing, considering I could get 35 rounds by just trimming the stock base/spring keeper. 

 

I plan to try the Taran +11 extensions. Or maybe the Springer Precision? I’d love to hear others’ opinions.

Hello: I use the Taran Tactical base pads with his spring. I get 41 rounds in the mag that is very loadable with a Maglula loader. I have not tried the TF or the Springer on my MPX magazines. Thanks, Eric

Two Springer extensions, and they work great with the extra power springs (and I still get 39 with no strain.  40 feels like something's going to break.)  Like others, no LRBO without it.  I keep a stock 30 for IDPA, though.

 

Have TF extensions for the Tavor and they're great too, but Springer has this wonderful cheap ($5) engraving option to put your name on the basepad.  I can be... forgetful of where I put stuff, and I like having my name etched into a magazine that's nearly a $100 investment after the extension.

Hi Eric - no feeding issues using Taran's uprated spring, and loading to 41 rounds? NICE! I think I'll be picking up a few.

Hello: I use them all the time for my matches. I actually have 4 of them on Gen1 and Gen 2 mags for my Gen2. I actually have two that hold 42 rounds so I can start with 43. Thanks, Eric

Hello: Looks like Taylor Freelance is coming out with a +20 round base pad for the MPX. 50-55 rounds with a 30 round magazine. I am guessing other makers will have one coming out as well. Thanks, Eric
