5.56MM INSAS LMG KI SIGHTON SE WAQFIAT

 

5.56MM INSAS LMG KI SIGHTON SE WAQFIAT

 

Parichay

 

1.      5.56mm INSAS LMG lambi range tak fire karne wala bahut hi kargar automatic hathiyar hai. LMG se dushman ko adhik se adhik barbad kiya ja sakta hai jabki firers ko iski sights ka sahi istemal karna ata ho. Iski anya accessory sights ke istemal karne se  LMG ki accuracy badh jati hai. Iski open iron sights ke alawa iske saath telescopic day light sight (TDLS),  aur passive night sight (PNS) ka bhi istemal kiya jata hai.

Bhag IV :  Beta Light Iron Sight ki Jankari

 

25.  Aam Jankari.  Beta light iron sight dwara raat ke samay shist lekar LMG ko fire kar sakte hain.  Roshni deine ke liye glass tube mein bhare tritium gas ka istemal kiya gaya hai, jo ek radio active padarth hai.  Front beta light iron sight, gas block par, foresight ke piche lagai jati hai.  Ismen ek tritum filled gas tube (TFGT) laga hai.  Rear beta light iron  sight sight leaf hai.  Rear beta iron sight ke dono TFGT ke beech ka ilaka rear sight aperture ke line mein hota hai.  Donon front aur rear beta light iron sight flip type hai aur jab inka istemal nahin ho raha ho to inhen niche gira diya jata hai.

 

26.  Istemal  Raat ke samay istemal mein lane ke liye donon beta light iron sight ko khara karo,  rear beta light iron sight ke do binduon ke bichon beech front beta light iron sight ko milakar sahi sight alignment hasil karo.  Tgt par shist lo aur fire karo.

 

27.     Glass Tube Tutne Par Savdhaniyan.   BLS ki glass tube tutne par nimn savdhaniyan honi chahiye.

(a)         Tritum hanikarak radiation (Kirane)  kam matra mein paida karta hai, islie firer ki aankh ko koi khatra nahin hai.  Agar firing ke dauran TFGT tut bhi jae to firer ko nuksan nahin hoga.

 

(b)         Agar khule ilaqe mein TFGT tuta hai to iske hanikarak padarth kirne vatavaran mein ghul jati hai aur iska asar kam ho jata hai.

 

(c)         Agar TFGT kamre ke andar tuta ho to us kamre ke sabhi vyaktion ko bahar nikal diya jae.  Kamre ke sabhi khirki/darwaje khol diye jaen kamre ke andar ek ghante tak kisi ko na ane diye jae.
