1000 Rounds of 62gr FMJBT 5.56x45 Steel Core Ammo by M.B.I.

The 5.56x45mm was created as a more powerful option over the .223 Remington. Although the two cartridges are quite similar externally, they’re very different internally, and for those reasons you should never fire a 5.56 round through a .223 rifle that is not specifically rated for it. 5.56 rounds have higher internal pressures, which is exactly what makes them more powerful to begin with. With the proper core a 5.56 can penetrate 15 to 20 inches into soft tissue although it’s prone to yaw when traveling through soft tissue in particular. And, of course, at a high enough velocity, that yaw can also cause fragmentation, which causes even more extensive damage. It’s a great military round, and if you’ve got a 5.56, you shouldn’t let it sit around. You need ammo.

These are 62 grain rounds, so they’re the standard weight for 5.56. They’re light enough to move at incredible speeds and powerful enough to tear into targets with enormous energy, and that makes them a formidable force, whatever your target may be. These are FMJBT rounds specifically made for target practice, tactical training, and plinking, and their Boat Tails make them a nice choice for practicing your long-range skills. The BT helps them resist cross-wind interference and gives them a more balanced trajectory as they travel. This ammunition zips down-range with lightning speed and impacts your target like a speeding train.

There are 1000 target rounds in sealed plastic bags here, and that’s pretty awesome. It’s made by M.B.I., Military Ballistic Industries, a company known for their precision manufacturing and exceptional quality. All of M.B.I.’s production takes place in America and every component must meet strict requirements. They take pride in their attention to detail and quality control. Although M.B.I. is known for their production of high-quality remanufactured rounds, these are actually brand new production brass cases with boxer primer. You can burn through all 1000 rounds, police your brass, reload, and do it all again. Your 5.56 is a seriously cool rifle, and it deserves ammunition worthy of it. Order some M.B.I. and feed it well next time you hit the range.

(Although 5.56x45 NATO does fit in a .223 Remington chamber, the 5.56 is a military, high-pressure round and is not recommended for use in a .223 Remington chamber.)
