Product Description

Adams Arms 16” Carbine Micro Block Tactical Evo 556 Upper

The 5.56 Carbine Micro Tactical Evo 16″ Upper is a standard mil-spec
upper that incorporates the patented Adams Arms technology and the
Samson Evolution extended free floating forearm. The piston system parts
and the barrel have been treated with our salt nitride Meloniting
process making them harder and more corrosive resistant than hard
chrome. The free floating forearm was manufactured for us by Samson
Manufacturing and is a 15″ tube that extends around the gas block,
giving you enough space to mount the removable picatinny rail pieces to
meet any of your needs. Add the patented Adams Arms piston system and
you’ll have an upper that will run cleaner, cooler, and longer than any
other AR upper you own.
