IWI Vented Front End Cap Features The IWI Vented Front End Cap is machined from steel and finished in a durable black Cerakote coating that resists wear and corrosion through repeated use in the field. Its vented design bleeds off excess propellant gas at the muzzle end which reduces the back pressure sent rearward into the action on over-gassed AR-15 and Tavor pattern rifles. Less back pressure means less gas blowback in the shooter s face and a noticeably cleaner-running action over a long session. At 6.4 inches long and 1.74 inches in diameter this cap is purpose-built to install directly onto the IWI IWS6 suppressor system. This cap is a direct-fit component for IWI s own suppressor lineup so installation is straightforward for anyone already running an IWS6 can. Choosing the vented version over the non-vented cap is a simple way to tailor suppressed performance to a specific host rifle s gas system without any permanent modification. IWI s decades of small arms manufacturing experience back the fit and finish of this accessory. For shooters running a gassy AR-15 or Tavor variant suppressed this front cap is a straightforward upgrade for cleaner more comfortable range sessions.
