2.3.5. LONG RAIL ADAPTER

optional long rail Adapter can be used if the firearm has a short
scope mounting rail which prevents the installation of the PS-40
forward of dayscope (Figure 2-3).
2.3.6. B.A.M. SYSTEM
optional B.A.M. system (Boresight Attachment Mount) is used to
install the PS-40 and dayscope on the rifles having short mounting
MIl-STD-1913 rail.
There are three advantages of the system:
• Low position of the sight and dayscope (36 mm above the rail).
• Incline of the axis of the dayscope and the sight on 20 angular
minutes for long range firing.
• Resistance on the rifle with vigorous recoil.
Install the PS-40 with B.A.M. system as follows (Figure 2-14):
1. Slightly loosen the two fixing screws [1] on the mount base [2].
2. Place the base on the mount of the fire arm [3].
3. Tighten the fixing screws of mount base.
4. Install the halves of plastic inserts [4] in the rings on the base.
NOTE:
There are two sets of inserts for scopes with 25.4mm and 30mm
tubes diameter.
5. Cradle the scope [5] in the rings (inserts).
6. Install the top halves of the inserts [6] and the rings [7] and tight-
en each ring's four screws [8] to finger tight.
7. Install the top of the mount [9] and tighten four screws [10] to
finger tight.
