5.56 NATO CBC SIERRA 77 GRAIN OTM (50 ROUNDS)

Out of Stock
Manufactured by Latin American defense contractor CBC, this 5.56 NATO ammunition is most notable for using Sierra OTM (Open Tip Match) bullets. The heavy 77 grain bullet is optimized for the needs of competitive shooters and delivers superior accuracy out to extended ranges. This is match grade ammo at a range grade price, so stock up and make a bunch of nice ragged holes!

CBC is a top ammunition manufacturer based in Brazil. The company supplies a variety of government clients and exports a great deal of ammo to the US under the Magtech brand.

These cartridges come in boxes of 50 and use non-corrosive Boxer primers and brass cases. You're probably going to need more than 50 rounds, so grab a few boxes and get free shipping from AmmoMan.com!

    I usually shoot 55 grain 5.56 in my AR15's. Got a Tavor which has 1:7 rifling and thought I would try 77 grain. It was already accurate, but this stuff was great. Can't give you group size, but shooting offhand and kneeing I was hitting 4-6 inch gongs at 100 yards without trouble.
