shotgun) or down (to raise the point of impact of the shotgun) then

ASSEMBLY/DISASSEMBLY OF SIGHTS

The STF 12 rifle has a B-045 front sight and a B-178-A ghost sight, both

removable.

1. Loosen the attaching thumbwheels located on the left-hand side of the

ghost sight or of the front sight (fig.15).

2. Insert the ghost sight and the front sight in the desired positions on the

Picatinny rail then tighten the side thumbwheels.

ASSEMBLY OF THE DOOR BREACHER

For the STF 12 versions with the door breacher, the shotgun can be used with or

without this accessory.

a- Without door breacher : An internal choke tube of the INNER HP type is

screwed into the muzzle of the barrel. It’s a CYLINDRICAL type (see

marking on the choke tube).

b- With door breacher :

1. Make sure that the weapon is totally unloaded. Engage the safety catch

of the weapon.

2. Put the choke key to INNER HP and turn the key counterclockwise to

unscrew the choke tube (fig.16).

3. Into the barrel, insert the specific choke tube E-311 for attaching the

door breacher and tighten it with the key (fig.17). Like the INNER HP

choke, this choke is a CYLINDRICAL .

4. Put the door breacher on the front of this choke, extending from the

barrel, and tighten firmly by hand, turning it clockwise (fig.18).

The door breacher has specific milling shapes to prevent it coming loose during

firing. Regularly disassemble the choke tube to clean it. Apply a little lubricant to

the threads to facilitate assembly and disassembly.

For more specific use of the STF 12, different choke tubes can be assembled:

IN/OUT HP, INNER HP, EXIS HP. Ask your dealer for advice.
