556/223

The Heckler & Koch HK416 is an assault rifle designed and manufactured by the German company Heckler & Koch. Although its design is based on the AR-15 class of firearm, specifically the Colt M4 carbine family issued to the U.S. military, it uses a proprietary short-stroke gas piston system from Heckler & Koch's earlier G36 family of rifles. It is the standard assault rifle of the Norwegian Armed Forces, selected by the French Armed Forces to replace the FAMAS, and was the weapon used by SEAL Team Six to kill Osama Bin Laden in 2011.

    So I bought this right around M114 and only took it to the range once. Gotta be honest, I loaded it to the max and had quite a few malfunctions with it. Reading reviews you can see that they're are sort of mixed. Maybe I loaded it wrong or it didn't like the ammo. Either way I'm never going to...

    New Henry HO23 556/223 300bko

    Just saw the new lever action from Henry and it's definitely gonna be a seller! Has the new linkage driven action, that seems to be the kicker for opting away from the long ranger model 223/556. Barrel is treaded, and feedback is a dream with 300bko. Hey it’s not for everybody🤘
