What is the XM320?
The U.S. Army XM320 program was the first fully competitive
service-wide procurement for an add-on 40mm grenade launcher
since the U.S. M203 was adopted in 1969.
The XM320 could be fielded as early as FY06 and will be
deployed with current and future service weapons including
the M16A2, M16A4, M4 and M4 MWS.
The XM320 provides the war fighter with five main system
components: Side-opening add-on 40x46mm launcher, various
optional sighting devices including day/night/ranging sighting
system, detachable multi-position retractable buttstock,
carrying sling for stand-alone use and field cleaning kit.
The XM320 design allows attachment to the host weapon by
the operator in the field in seconds and without the need
The XM320 program successfully leveraged existing Commercial
Off-the-Shelf (COTS) technology and rapid acquisition procurement
methods to field the XM320 to the war fighters early.
The XM320 has proven to be a highly reliable and accurate
grenade launcher with complete system modularity to provide
operational flexibility for the user.
The U.S. M203 has been in service since 1969. It does not
provide modularity or stand-alone capability, is not compatible
with longer length special purpose munitions, cannot be
mounted by the operator and does not offer the first round
hit probability, day/night and ranging capabilities of
The XM320 will provide a common grenade launcher that can
be used on current and future platforms through the use
of various mounting adapters.
M203s cannot be used in a stand-alone mode for special
purposes that include riot/crowd control, firing from vehicles
or as supple-mental weapons for special missions.
The XM320 ensures improved first round hit probability
by providing accurate range-to-target data and 5 meter
aiming increments to engage and defeat enemy targets with
the first round.
High Payoff, Low Investment
The use of proven COTS subsystems, full and open competition
and accelerated procurement methods, ensures delivery of
a combat ready system with complete logistics support at
the best value to the U.S. government.
Preplanned Product Improvements offer enhanced capabilities
to include increased munitions range and target effects,
reduced felt recoil, reduced system weight, full solution
fire control system and pre-programmed air bursting capability.
What is New Here?
The procurement for the XM320 was conducted as a full and
open competition with all interested manufacturers free
to submit test samples for an optimal launcher.
