Q

This type of firearm has a magazine under the bolt. The tubular magazine is one of the
types of compartments used for its cartridges. To open the breech, move the bolt handle upward, then draw it to the rear. Bringing the bolt handle forward, allows the bolt to carry another fresh ammunition and load to the chamber. Finally, move the handle downward to lock the breech and
prepare for the subsequent firing.

22
Q

This type of firearm can be operated through the manipulation of the for-end. It can be
done by bringing the for-end back and forth. The backward movement of the for-end causes its bolt to be dragged backward. Likewise, this motion results in the extraction and ejection of the empty cartridge out from the firearm through the ejection port. On the other hand, the fresh ammunition from the tubular magazine will be carried by the bolt towards the chamber when the for-end is brought forward.

A

Slide Or Pump Action Type

23
Q

The trigger guard of this firearm can be moved up and down The downward
manipulation of the trigger guard, opens the breech and further moves the bolt mechanism to the rear. This motion also extracts and ejects the case from the firearm. Fresh ammunition will be loaded to the chamber as the trigger guard is raised. This condition is now ready for firing

Caliber, Number of lands and grooves, Width of lands, Width of grooves, Direction of twist, Pitch of Rifling, Depth of Grooves

29
Q

it refers to the characteristics that are even before the manufacture of e firearm. These are factory specifications and within the control of man. These serve as e basis for identifying a certain group or class of firearm.

A

CLASS CHARACTERISTICS

30
Q

This refers to the diameter of the bore which can be determined by measuring the two opposite lands. The land are the basis for measuring the caliber of the firearm since they are the remnants after rifling operation. The manufacturer could have met the actual caliber of the firearm prior to this phase in making the barrel

A

Bore Diameter or Caliber

31
Q

There should be an equal number of lands and grooves in the barrel regardless of the manufacturer. If the bore has six lands, then there should also be six grooves.

A

Number of Lands and Grooves.

32
Q

The elevated portions inside the bore of the barrel.

33
Q

The depressed portions inside the bore of the barrel.

Q

The ridges of metal between the grooves in a rifled bore

38
Q

This can be determined through measuring the distance from the edge of the land to its opposite edge.

A

Width of the Lands

39
Q

It can be determined by measuring the distance from the corner of the groove to its opposite corner.

A

Width of the Grooves

40
Q

It refers to the twist of rifling in the barrel. The twist of rifling may either be left or right. The examiner can identify the twist of rifling in the barrel by viewing either from the muzzle end or breech end since the results are the same

A

Direction of Twist

41
Q

The act or process of making spiral grooves

42
Q

A system of spinal grooves inside the barrel of a gun causing a bullet when fired to spin about its longer axis.

Q

This is always equal to the height of the land. To determine its measurement, take first the diameter between land to opposite land and groove to opposite groove respectively. Next, subtract the measurement of land to opposite land from the diameter of the groove to the opposite groove. Lastly, divide their difference by two (2). The result is the depth of the groove or the height of the land.
