42, 43 and 44 VI. Weapon Maintenance 1. Overview 22 Each shooter is responsible for the maintenance of his rifle. The Group and Section Chiefs as well as Unit Commanders of reserve units are responsible for periodic weapon inspection. The group and section chiefs will perform an inspection and comment on all maintenance issues such as the condition of the barrel, cleanliness and so forth.
44 (cont), 45 and 46 29 Barrel cleaning is performed by means of a cleaning cord, after having removed the bolt and the magazine. For Mq. 31 the locking sleeve should be re-inserted in place to ensure that the ejector does not snag the cleaning cord. The cleaning cord is inserted through the receiver.
46 (cont), 47 34 If a major inspection is required, contact the responsible officers. A major inspection should take place at least one time during short time active duty and once every two or three weeks during prolonged periods of active duty. This inspection is composed of the following elements: a) b) c) d) e) f) g) h) i) j) k) l) m) n) Remove all cartridges, the bolt and the magazine.
48,49 VII. Scoped Rifles A. Scoped rifles 1931/42 and 1931/43 1. Overview 35 There are two Model 31 Scoped rifles: Model 31/42, scope power 1.8X Model 31/43, scope power 2.8X The scope is set offset in the model 31 rifle. Because of this the regular iron sights can be used as well as the scope. The nomenclature of the different parts of the scoped rifle is outlined in fig. 19 and 20. The scope reticle is shown in fig.21. 2.

51, 52 and 53 After shooting, the mobile objective must be lowered into its slot in the stock and lower the elevation slide to 1. If the objective remains raised, it can be easily bumped. The thickness of the reticle crosshairs is 0.5 0/00. The thickness of the auxiliary crosshairs is 2 0/00 . The visual field of Model 41/42 (magnification 1.8X) measures 1250/00; The visual field of Model 31/43 (magnification 2.8X) measures 800/00. Fig. 21 B.
53 cont, 54 Additional infor mation 40 The scope can be removed. A bayonet can be mounted to the barrel. The rifle can be aimed with the iron sight with the scope mounted to a distance of 800 m. Compared with the Mq. 31 the Mq. Lu 55 has a smaller target dispersion pattern due to the weight of the weapon and the barrel muzzle brake. A good marksman, using the bipod, and after sighting in, can achieve 95 points in 10 shots at a 300 m 10 point target. The weapon is adjusted to a 300-meter zero.

57,58 For the scoped rifle, it is important to pay attention to the following points: Use the weapon with care to avoid impacts, wet and dirty conditions. If the scope gets wet, dry it at room temperature, not next to a heater on not in its case. The lenses should be cleaned with a clean lens cloth or a chamois. Sand particles should be removed preferably beforehand with tweezers. Metal scope parts should only be lightly oiled. The lenses should never come in contact with grease or petroleum based oils.
59, 60 Fig. 27 29 Countersunk screws for windage adjustment (loosen 1 turn) 30 Elevation knob 31 Focus ring 4. Sight adjustment procedure 43 As a general rule, the scoped rifle will be fired using the bipod; or per the situation, perhaps supported on sandbags or on a window frame Before each shot, the diopter adjustment will be inspected. For the Mq. 31, small corrections in windage and elevation are made by changing the sighting point; the procedure is the same for the Mod.
61, 62 For this reason; one should not, as a general rule, adjust the knobs unless the impact point is at least 0.5 0/00 off center or is at least 15 cm off center at 300 m. 5. Weapon Use 44 The Scoped Rifle Model 55 is a weapon for advanced marksman, with which small, important targets can be engaged at long distances. The success of an elite marksman equipped with a Scoped Rifle is dependant on the following conditions: Only marksmen who have proven themselves extremely competent using the Mq.
63,64 a) Supports The fundamental rule for shooting, sitting and standing, is to put the left side of the body forward and in general support the body against a solid mass (tree, wall etc.). The sling can be wrapped around the around to give the weapon greater stability. In order to shoot more accurately, the bipod and other supports that permit the shooter to have a selection of good positions.
65 Fig.
66, 67 The shooting program should contain the exercises mentioned the Chapter 8 and can be developed according the circumstances. Where it is not possible to shoot over an open field, camouflaged targets mu st be used. In this situation, only sight in on the center of the target. In normal situations, the choice of shooting positions should change; shooting in a sitting position should be practiced as well as other positions.
68, 69 Part 2 Munitions I. Overview 47 Ammunition for long rifle, musketoon (short rifle), Automatic rifle, and machine gun are delivered to troops ready to fire. They are all the same. The cartridge is composed of the bullet (projectile), the propulsive charge, and the case. The bullet is inserted into the neck of the case. In order to hold the bullet tightly and seal the interior of the case, the case neck is crimped into a circular groove near the base of the bullet.

Common Ball Cartridge 11 (Fig. 29 and 30) 48 There are three types of ball ammunition: -Common Rifle Cartridge 11, 7.5 mm caliber -Armor Piercing Cartridge, 7.
72, 73 Exterior Characteristics: No color code on the base of the cartridge. 2. Armor Piercing Cartridge 50 The armor-piercing bullet is similar in shape to the common bullet. The cylindrical part is slightly longer. A specially hardened steel core and wrapped in lead is found inside the bullet. The armor piercing cartridge is used shoot lightly armored targets that it can perforate at short distances. The penetration power diminishes rapidly at longer ranges and if the bullet hits the armor at an angle.
74, 75 Fig. 31 Handling Cartridge Blank Rifle Cartridge Blank Automatic Rifle Cartridge Blank Machine Gun Cartridge 53 Shooting blank cartridges labeled “Blank Automatic Rifle Cartridge” (with a green wooden bullet) and “Blank Machine Gun Cartridges” in a rifle is prohibited. 54 On the exterior the special cartridge for the Pz-WG. 44 and Ex-WG. 44 resembles the Blank Machine Gun cartridge. This cannot be used except with the short rifle for use as the propulsive charge for antitank grenade.
76, 77, 78 V. Packaging 56 The charger with 6 cartridges and the package of 10 cartridges are the smallest available Packages.
78 cont, 79 60 When choosing a storage location, an uninhabited and isolated place should be chosen, if possible. Good storage locations for munitions will be dry, easy to aerate and provided with a floor. Storing munitions on rock or dirt will damage the packaging. If the packaging becomes wet and impossible to transport in cartons, find a dry floor and ensure that there is sufficient aeration in the storage area. Stacking cartons more than 5 cartons high is prohibited.
81, 82, 83 -Place the left thumb over the loading slot (fig. 36) -Open the bolt with the right hand, and push the exposed cartridge downward into the magazine with the right thumb. -Remove the magazine with the right hand and lower the rifle, bolt open, and lean it against the body. -Take the magazine and the empty charger in the left hand with the points of the cartridges toward the shooter, -Transfer the cartridges from the magazine to the charger (fig.
83 (cont), 84 While bringing the weapon to the shoulder, the shooter will calmly inhale and exhale, set the rear sight in one click, hold his breath, sight and pull the trigger with the index finger until the weapon discharges. After firing, the shooter will stay for a moment in the same position, asses s the shot (during training, the shot execution is announced out loud after firing) and observe, if possible, the effect on the target. He then will reload per section 63.
85, 86, 87, 88 Every rifle has it’s own aim point, that can vary depending on the eye of the shooter, the resolution of the target as well as other factors. If the distance off target is small, the shooter will adjust the aim point by himself to adjust for the distance by observing where the shots hit the target. Otherwise, if the shot distance off target is large, then the front sight should be moved or changed.
88 (cont) 9. -When shooting toward or over friendly troops, the friendly troops should not be more than 100m from the weapon and in all cases at a shorter distance than that of the target. -When shooting over friendly troops, the trajectory should pass 5m or more over the troops so the same are not found at a “dead angle”.

110, 111 Appendix IV Instructions for avoiding Small Arms Damage Avoid Weapon Damage! Shooting foreign ammunitions or non-issued ordnance with your weapon can destroy it
112, 113 1. How do you avoid barrel bulging? -Never plug the barrel of your rifle with cleaning patches or grease. -Ensure no dirt or snow gets in your barrel, especially while not in combat exercises. -Never attempt to clear a barrel blockage with another discharge of ball or blank ammunition. -Before each shot, make sure the barrel of your weapon is clear. Remember That: Shooting with a plugged barrel will cause the barrel to bulge. If a barrel bulge is to occur, the barrel will be changed at your cost.
114,115 Shooting with a blocked barrel will cause a barrel bulge Bulged Barrel Fractured Bulge Blocked, exploded barrel Exploded Barrel Before each shooting session, check to ensure the weapon is not blocked! Barrel Inspection Before each shooting session, especially under combat conditions, make sure that the weapon is not blocked. By performing this inspection, you will avoid a barrel bulge, in other words, unnecessary expense to the State and to yourself.
116, 117 The barrel must be replaced if it is bulged 2. Take care of your weapon! Manage your weapon to ensure wise treatment and proper handling. -If you shoot when the handle is not all the way forward, you run the risk of breaking the cam follower pin. -Incorrectly disassembling the magazine will break the spring. -The extractor should not be disassembled unless necessary. If this is required, do it correctly. -Entrust the adjustment of the sear to a gunsmith, who has been trained in this repair.
118, 119 Take care of your parts! Broken Cam follower pin Incorrect Correct If you shoot when the handle is not all the way forward, you run the risk of breaking the cam follower pin Magazine Disassembly Broken Magazine Spring If you pull the magazine plate out like this it will break the spring Rock the plate and turn it out
120, 121 Losing a Magazine! Loss of a magazine due to poor placement in the weapon. When inserting a magazine into your weapon, check to make sure it is locked into place. This way you will avoid losing it. Removing the extractor The extractor should only be removed when necessary WRONG! You will deform the extractor removing it in this fashion. Correct! Lift lightly to remove.
122, 123 Sear adjustment Troops in the field are prohibited from adjusting or tampering with the rifle sear. Only gunsmiths may adjust the sear of a rifle. Forcing or grinding the sears damages your weapon and runs the risk of causing and accident. Rounded Sears You will damage in this fashion, the parts of your weapon, parts that will need to be replaced. Avoid damaging your rifle stock The butt is not a sledgehammer.
124, 125 Stock disassembly for the Mod. 11 Removing the hand guard WRONG Correct Do not forget to raise the sight leaf vertically and remove the hand guard by turning it perpendicular to the barrel. It is not prudent to lean your weapon against a wall, a fence or a door. If it falls it will be damaged. You will damage your comrade’s weapons by carrying them this way.
126, 127 3. Cleaning and greasing the barrel -Take care of the barrel of your rifle and avoid oxidation by proper cleaning and greasing. -After each shooting session, immediately grease the barrel with the help of a cleaning rod and brush. (The barrel should still be warm.) -As soon as you return to base, clean the barrel by means of a cleaning cord. Pay attention to pull the wire mesh through in the correct way. The wire mesh should be well greased. Inspect for cleanliness and regrease the barrel.
128, 129 Take care of your cleaning cord! WRONG! Without the locking sleeve, the cord will snag on the ejector as it passes Correct! Insert the locking sleeve
130, 131 Ovalization of the muzzle Using this cleaning method will ovalize the muzzle of your barrel. A barrel with an ovalized muzzle, loses its accuracy. Ensure the cleaning cord is always pulled down the axis of the barrel. Normal Muzzle Ovalized Muzzle Avoid scratching the inside of your barrel! Sand will scratch the interior of the barrel. Keep grease and cleaning articles clean Before inserting the cleaning rod into the barrel, clean the rod with a clean cloth.
132, 133 4. Shooting with a reducer tube If you fired the weapon with a reducer tube, Please note the following points: -Upon completion of shooting, remove the reducer tube from the weapon. -Thoroughly clean the barrel and the chamber. Remove all powder residue or lead. -A deep cleaning of the chamber is very important. While shooting with a reducer tube, an amount of residue will be deposited in the chamber. If cleaning is neglected, there is a risk of malfunction (jammed case). Reducer tube for Mod.
134, 135 5. Using the Muzzle Cover -Protect the rifle barrel with a muzzle cover. -Aside from issued muzzle covers, other cover are authorized for use, such as celluloid, bakelite or other soft material or metal, providing they fulfill the following conditions: 1. 2. 3. Weight not greater than 1.3g Held to the barrel by slots that provide space so the barrel is not hermitically sealed. Will not cause the barrel to be sealed by grease or a patch. (risk of barrel bulge) Bakelite Steel 6.
136, 137 Weapons where the impact point is offset should be sighted in. Sighting in is a gunsmith’s job The gunsmith has in his equipment, several types of front sights that will allow him to adjust the elevation of the impact point. The windage adjustment is accomplished by moving the front sight. If moving the front sight will not change the impact point, for example while shooting during off-duty. Refer to the cantonal arsenal that is closest to your domicile.
