Owner’s Manual 2016

Ammunition

The FN PS90

Carbine should only be used with 5.7 x 28 mm

ammunition.

This is indicated by the inscription engraved in the rear left side of the

barrel support.

The barrel and the breech block of this carbine have

been made with substantial safety margins in order

to be able to cope with the pressures developed by

the 5.7 x 28 mm ammunition especially conceived

by FN HERSTAL.

Nevertheless, FN HERSTAL / FN AMERICA cannot

assume any responsibility for incidents which result

from the use of rounds of different caliber or not

fabricated according to the FN HERSTAL standards.

EXAMINE EACH ROUND BEFORE YOU PUT IT IN

YOUR CARBINE !

Safety features

The fire selector is the only apparent external safety device of the

FN PS90

Carbine : when this fire selector is at the position ‘S’

(safe), it is impossible to operate the trigger.

The FN PS90

Carbine has however also been provided with an

internal safety sear which ensures that, during the forward

movement of the moving parts, the hammer is blocked until the

breech block has reached its most forward position : this avoids

any risk of accidental firing when the carbine is (involuntarily)

dropped.

The safety features of the FN PS90

Carbine ensure that the

carbine can be carried safely and that it nevertheless offers a

permanent, rapid firing readiness without having to carry out

complicated manipulations.

Please note that failure of a safety device can occur when the

carbine is subject to extreme forces or conditions normally not

encountered in a normal use environment.

Only use specially coated factory loaded

ammunition.

The use of any non-factory loaded and coated ammunition

can result in pressures leading to personal injury as well as to

damage to the firearm.
