Battle Proven Rail System
Specifically developed for the US Navy E.O.D. Groups (Explosive Ordnance Disposal), the CASV-EL has become a Battle Proven rigid mounting platform, respected by all end users. The CASV-ELS is a variation for a user
with special optic needs. Like all CASV systems, the CASV-ELS relies on
"piggy-back" mounting to the top of a “flat-top” M4 upper receiver. But what
makes the CASV-ELS different is its forward “Stepped” top rail portion. This
forward rail allows the optic (such as most EOTechs) to be placed at the same
plane/height as the weapon’s back-up iron sights, i.e. “co-witness”.
Co-witnessing allows the end-user to sight-in the optic to the back-up iron
sights or vice-versa. This means less time at the range, while sighting in the
Like the CASV-EL, this model is a “drop-on” rail system for a Carbine-Length
gas system that is equipped with a fixed sight-tower/gas block system, as
commonly found on most 10.5”, 14.5”, and some 16” barrels. The system also
features a removable lower handguard, which allows the access of an M203
barrel-mounted grenade launcher. The smooth body construction allows multiple
rail mounting points, adaptable to any mission needs. Each CASV kit features
various lengths of removable rails and mounting hardware.
Like all CASVs, the CASV-ELS relies on the use of the Delta Ring for a more
secure mounting point. Vltor does not recommend that any CASV handguard be used
without the standard Delta Ring assembly. This CASV chassis is made
entirely of aluminum, with the exception of the stainless steel mounting
The installation of this handguard does not require any modifications to the
firearm except for the removal of the sight tower sling swivel (if your carbine
is equipped with one).
The CASV-ELS contains the following Items:
6-inch Accessory Rail
Qty.2 4-inch Accessory Rails
Qty.13 10-32 x ˝ Flathead Hex Drive Screws
Wrenches for Mounting Clamp and Accessory Rail Installation.
The CASV-EL is one of the simplest rail systems to install, requiring no special installations tools. All that is needed is to remove the pinned in sling swivel located on the front sight tower assembly. Each handguard assembly has a rigid continuous rail section along the top, and comes with removable rail sections that allow the user to install rail sections where needed.
Fits all flat top receivers, carbine length gas systems M4 AR15 carbine series system. This system will not work with Mid-Length or Rifle Length gas systems.
