MCX DREM BUILD
as the cost of the base rifle. When real
CTSFO were seen with suppressed rifles
this rail also became a must-have and
then the search was on for a suppressor
with the right “look” for the impression.
A small number of similar looking dummy
suppressors were CNC manufactured
by JTac Custom Ltd. The “cans” had the
ability to accept the Xcortech XT301 tracer
unit as well as some foam discs, so that
users had the option to use tracer BBs in
game.
Fast-forward to 2019 and with the
discontinuation of the Cybergun MCX,
SIG SAUER® announced that they would
be taking the control of the Virtus MCX
in-house, under the ProForce banner and
customers were then eagerly awaiting the
release of the new AEG rifle. When SIG
decided to stop making the older model of
MCX (now known as the “Legacy” MCX)
the new model would be called the “Virtus
MCX”. (For an in-depth review of the
Cybergun MCX, check out Scott’s report in
the April 2018 issue of Airsoft Action.)
THE SAME, BUT DIFFERENT
There are a few differences between the
Cybergun “Legacy” MCX and the ProForce
Virtus MCX AEGs:
• Gas Block: this has the new Virtus
looking gas plug.
• The outer barrel is longer than on
the Cybergun Legacy MCX by 75mm
(3”) difference. The Legacy was fitted
with a 195mm outer barrel (and also a
removeable 10mm extension), whereas the
Virtus comes in at 280mm. It also has a
flat portion on the top of the barrel, which
nicely addresses the problems with the
Cybergun rifles where it was a nightmare
to get a battery to fit. The battery storage
on the ProForce is also helped by cutting
down the mock gas piston would be and
was on the Legacy rifle. For those who
really prefer the battery and wiring not to
be seen, wrap them in fabric tape and they
almost disappear inside the rail. A good
feature with the outer barrels on the AEGs
is that they are interchangeable between
the Legacy and Virtus models. There is
also an option for a 6.75” barrel which is
available through Virtus Training Systems
Ltd.
• A huge difference in the rails is obvious,
as the Legacy was Keymod and the Virtus
is MLok. Another big difference is the
overall length of the rail. Legacy comes in
at 203mm and 41.5mm wide, where the
Virtus rail measures at 262mm long and
43.5mm wide. The Picatinny rail on the top
of the receiver is also changed to mirror
the differences in the real rifles. The Legacy
has a rounded profile whereas the Virtus is
the standard flat in the same
way you’d see on something
like an M4.
Small differences between
the two versions are that
the Virtus has the addition
of “Exeter-NH-USA” under
SIG SAUER INC on the
receiver, while the ejector
cover is slightly set back on
the Virtus model and also
has nice “Virtus” and Logo
engraved on it. Looking
underneath the rifle around
the trigger guard, we can
see the Pentagon with
“F”, which means it will
be accepted in Germany,
provided it is converted to
semi-auto only. There is also
a warning on the base of
the trigger guard to “Wear
eye protection – this is
not a toy – Read Owner’s
Manual” etc.
Other than those
differences that have been
noted, it is essentially a
common lower, gearbox,
controls etc between the
two models.
Usually I am one who
may change a hop rubber
and stop there, but for
this Virtus MCX I decided
I would “upgrade” a rifle
and then make some side
by side comparisons on the
range.
Dan, from Tactical Parts
in the USA and the tech
behind the excellent Black
Swan Dynamics custom
builds, has completed a
similar upgrade build for
my KWA T6. Here he lays
out the upgrade work on
my ProForce MCX.
The MCX “Wolf
Mod”
This upgrade is based
on previous work with
upgrading a KWA T6 for
my colleague at UK’s JTAC
Custom, something now
colloquially referred to as
the “Wolf Mod.”
Distilled down to the
nuts and bolts, the “Wolf
Mod” is a full makeover
of the internals with a

ratio, upgraded motor
