The GSG-5 in cal. .22lr is a product
of German Sport Guns (GSG), with its
location in Ense-Höingen / Germany.
The GSG-5 was designed and
constructed by a team which use 3D
Cadcam Technology.
The trigger on the GSG-5 is very similar to an
MP5 trigger-- in other words, long and somewhat
heavy. The rear sight is a rotating disk like on
HK rifles. Along with the wide front post, this
sight setup isn't great for precision. However
the construction of the GSG-5 is not identical
to the MP5. The GSG-5 comprises two aluminium
upper receiver halves which are joined together
with a series of screws. The bolt assembly is
captured. Here the four screws that hold the two
clam-shell sides of the upper receiver together
are visible (three left, one top right) inside
the upper. The lower receiver is moulded plastic
and contains the trigger group, which is not
interchangeable with MP5 trigger groups. The
stock, lower receiver, and fore-end are held on
with three large pins which screw together much
like the rotation joint on an FN-FAL. To save on
weight, the barrel diameter is pretty thin. It
is not exactly free-floated, however, it only
contacts the rest of the gun near what I'll call
the trunion, where the forward extent of the
aluminium upper receiver is joined by three
screws, and just under the front sight base.
Standard-capacity GSG-5 magazines hold 22 rounds
of .22LR and the follower can be retracted to
make loading easier. The GSG-5 operates by
direct blowback; the bolt is not locked in
battery. The bolt locks back on an empty
magazine, and the GSG-5 has a magazine
disconnect safety.
Only a few potential problems exist with the
GSG-5. The first was that several screws came
loose, specifically: (1) the screw that holds
the magazine follower together (side to side);
and (2) the rear sight screw. The former
comprises a very small nut and bolt, and either
would be extremely easy to lose. The one on the
demo gun fell into the snow and I was very lucky
to be able to find the approx 0.10"-wide nut. I
would recommend going over the GSG-5, make sure
everything is tight, and then use removable
loctite to secure the fasteners. The other small
issue was that the cocking tube was peening
slightly on the outside surface of the notch
which locks the bolt back.
