We were fortunate to test
M16 Clinic’s new product, the M16 VIPER entry upper.
When we first opened the box and saw the M16 VIPER,
everyone had that little, bad-boy giggle working. The
upper impressed us immediately due to its size. The
quality was as expected, very high. Our Department has
dealt with Greg Leaf at the M16 Clinic in the past and
we are very impressed with his commitment to quality.
The fit and finish of the M16 VIPER is excellent. The
finish so impressed us when we matched it against other
manufacturers’ uppers in our inventory. The results were
predictable. The quality of the M16 VIPER was superior
to that of all the others.
Day One at the range.
We conducted dry vehicle assaults and simulated building
searches with the M16 VIPER attached to a conventional
M16 full auto lower receiver with CAR (collapsible)
stock. The compact design of the M16 VIPER allowed for
more efficient vehicle assaults. When the operator
approached the vehicle, he was able to attain a better
dominant muzzle direction at the vehicle.
building clearing and room clearing, the M16 VIPER’s
compact size again provided the operator with more
mobility and control. Operators (MCSO Special Response
Team members) commented that they felt more confident
because they were not “telegraphing” their movements as
much with the M16 VIPER, compare to a conventional
length barrel. The short design benefits the user if a
struggle ensued, causing a weapon retention scenario.
Day two at the range. Our first live fire
exercises with the VIPER were done in semi auto mode. We
found that the weapon held accuracy very well out to
fifty yards. At the one hundred yard mark we were able
to hit five-inch paper plates with almost every round.
We currently use 11.5” barrels on our M16s that were
accurized and tuned last year at the M16 Clinic. We saw
no difference in accuracy between the M16 VIPER and our
11.5” tuned uppers. We put over five hundred rounds
through the M16 VIPER in semi-auto with no malfunctions.
We then did two shot bursts, three shot bursts,
and full auto. Due to Greg’s design, the M16 VIPER
performed as we had expected. We were able to get two,
three, and four shot bursts in the full auto mode. The
weapon was so controllable, we easily fired one round
shots on full auto. The shot groupings of the bursts
were within one inch of each other from three feet to
thirty-six feet. Going to full auto, we put one thirty
round magazine through the M16 VIPER at three yards. The
operator was able to keep all thirty rounds inside the
five-inch paper plate. The control of the weapon was
very smooth. The M16 VIPER performed without any
In closing, M16 Clinic’s M16 VIPER
upper receiver would benefit any tactical team.
