If accuracy, reliability and durability is what you are looking for, then look no further. The Mk4 ESR11 is not only a sub-MOA rifle, it is extremely common for proficient shooters to achieve 3/4 MOA or better with factory match ammo. On top of the extreme accuracy, the Mk4 ESR11 has the smoothest trigger break and cycling with virtually zero recoil, so detecting round impact and follow up shots are a breeze. If that wasn’t enough, the Mk4 ESR11 will be the most ergonomically comfortable .223 / 5.56 AR platform rifle you will ever operate. Considered by some to be the American answer to 7.62×39, 300 Blackout has been modified to use the same magazines and bolt as the common 5.56 NATO. 300 Blackout allows for shooting of various grain weights and performs exceptionally with subsonic ammo and suppressors.
