Now I have 2 more.......
Hello. These 2 mags are part of My MPX ("upgrade") Project. I already had 4 with TF +10 extensions, and these 2 new ones will have the new TF +20 extensions. As for function, They won't get used for 2-3 more weeks, since the MPX project is still waiting on the Sig adapter (still on back-order) that is needed to swap out the OEM Buttstock. Hopefully by mid-May..... But, since I already have several of these mags, I have no doubt that they (the new mags) will be flawless in function, just like the "old" ones. Kudos go out to Brownell's for the Service and updates provided (for the back order), during and after My purchase.
