Maxim Defense 5.56x45mm NATO 62gr Tumble Upon Impact (TUI) Solid Copper Spun Lead-Free 20/Box is designed to produce optimized close-quarter defense velocities and terminal performance in short barrel rifles (SBRs). SBRs sometimes lack the velocities and terminal ballistics that rifles with longer barrels produce. Maxim Defense, in partner with Fort Scott Munitions made specific adjustments to produce ammunition optimized specifically for SBRs in close-quarter, home defense and personal defense situations. This ammunition features a non-lead, Solid Copper Spun (SCS) bullet and utilizes Tumble Upon Impact (TUI) bullet technology which produces ballistic wound cavities that exceed the standards of both expanding and fragmenting bullets. The design of the TUI bullet causes the bullet to tumble down to 500 Feet Per Second (FPS). In confined areas and close quarter defense situations, the TUI bullet is also designed to lose momentum, so it is less likely to cause collateral harm to bystanders or structures. This powerful round provides exceptional accuracy, and is also reliable for hunting. This ammunition is new production, non-corrosive, boxer primed, in reloadable brass cases.

Please Note: This ammunition meets and follows SAAMI guidelines and standards.

  • really nice 5.56 nato ammo

    Posted by Kyle Ryder on Sep 14th 2020

    I bought three boxes of this ammo last month and I was very pleased with the accuracy out of my rock river sbr. Out of my 7in barrel this ammo was very accurate with no issues to speak of. I like the uniqueness of this ammo and that it is made for short barrel rifles. The recoil was tolerable and I would feel confident in keeping it loaded in my rifle for up close defense situations including home defense. After watching youtube videos I am even more confident in the abilities of this ammunition. As soon as your company has more of this in stock I will be buying more. I would like to have at least ten boxes on hand. I called and spoke with Zak and got on the fcfs list for ten boxes of this ammo. Thanks again for the incredible customer service. Your company is the best! I am telling everyone I know to visit and buy ammo on munitions express.
