LWRCI IC-MKIIR 5.56 NATO Tungsten Gray Rifle

A: No sir. If it were 223 Wylde that would be stated as such. You can shoot both 223 and 556 out of it safely.

A: Hi Ryan and welcome. The barrel is actually stamped 5.56NATO so it will shoot both 5.56 and .223 ammunition no issue. Cheers and stay safe!

A: sorry its not a 223 Wylde it is a %.56 nato and can also shoot .223 ammo

A: Hi Ryan, no sir, a .223 Wylde chamber is not the same as a 5.56/.223 chamber, although it can shoot both cartridges. The .223 Wylde chamber, designed by Bill Wylde, is a hybrid chamber that combines the best features of the .223 Remington and 5.56 NATO. The Wylde chamber has a 0.224″ diameter and a 1:8″ twist rate, allowing it to accommodate both .223 Remington and 5.56 NATO cartridges. In contrast, the 5.56 NATO chamber is a standardized design adopted by NATO countries for military use. It has a slightly larger diameter of 0.226″ and a 1:7″ or 1:9″ twist rate. The 5.56 NATO chamber is designed to fire the 5.56x45mm cartridge, which has a slightly longer case length and overall length compared to the .223 Remington. The NATO chamber's freebore is typically longer than that of the Wylde chamber. . This gun is chambered in 5.56 (not .223 Wylde) so it will safely shoot both 5.56 and .223 . Stay safe & have a great day!
