Built around a two-position short stroke gas piston, the all-new IWI ARAD 5 is an enhanced M4-pattern rifle chambered in 5.56 NATO. It utilizes IWI's patented CamLok quick-detach barrel mounting system and features a semi-monolithic upper receiver. The ARAD 5 is optimized for both suppressed and unsuppressed shooting in even the harshest environments. And with M-LOK attachment points at the 3, 6, and 9 o'clock positions, this modular rifle can be configured for any mission. The 4150 CMV barrel is threaded 1/2x28, so shooters can easily direct thread suppressors or use their preferred QD suppressor mounting system.
