Question

The weight of 7.62 mm SLR rifle is _________

• A. 5.1 kg
• B. 5.0 kg
• C. 4.2 kg
• D. 4.4 kg

Hint:

To remember the weight system of the SLR, keep this formula in mind: $$\text{Dry Weight (4.4 kg)} + \text{Loaded Magazine (0.7 kg)} = \text{Loaded Weight (5.1 kg)}$$

Answer 1

The Correct Option is D

Step 1: Understanding SLR Technical Specifications:
The $7.62\text{ mm}$ Self-Loading Rifle (SLR), commonly known in Indian service as the Ishapore $1\text{A1}$, is a standard combat weapon used for infantry training. Memorizing its technical parameters is a fundamental part of weapon training in the NCC.

Step 2: Differentiating Between Unloaded and Loaded Weights:
A rifle's weight varies depending on the presence of accessories and ammunition:
• Rifle Alone (Dry/Unloaded Weight): The basic weight of the weapon without a magazine, bayonet, or sling is approximately 4.4 kg (specifically $\approx 4.39\text{ kg}$).
• Weight with Full Magazine: A standard $20$-round box magazine filled with $7.62\text{ mm} \times 51\text{ mm}$ NATO ammunition weighs approximately $0.7\text{ kg}$. Adding this to the dry weight brings the total loaded weight to 5.1 kg.
• Weight with Bayonet: Attaching the bayonet adds an additional $0.35\text{ kg}$.

Step 3: Choosing the Correct Option:
In standard weapon training manuals, the primary reference weight of the basic weapon itself (without accessories) is listed as $4.4\text{ kg}$. Thus, option (D) is the correct answer for the dry weight of the SLR.
