Army Officer is partially right, IA use good Captured AK also the ammo, One more thing many Member may dont know that IA men use entirely
AKMs not AK-47, AKM are better..
Here some comparison:
The AKM:
AKM: 3.6 kg (7.94 lb) with full magazine
http://en.wikipedia.org/wiki/Gun_barrel
Improvements: Compared to the AK-47, the AKM features detail improvements and enhancements that optimized the rifle for mass production; some parts and assemblies were conceived using simplified manufacturing methods. Notably, the AK-47's milled steel receiver was replaced by a U-shaped steel stamping. As a result of these modifications,
the AKM's weight was reduced by approx. 1 kg (2.2 lb), the accuracy during automatic fire was increased and several reliability issues were addressed. The AK-47's chrome-lined
barrel was retained, a common feature of Soviet weapons which resists wear and corrosion, particularly under harsh field and ammunition conditions.AKM was fitted with a slant cut
muzzle brake that helps redirect expanding propellant gases upward and to the right during firing,
which mitigates the rise of the muzzle during an automatic burst when held by a right-handed firer.
The AK-47:
AK-47: Weight 5.21 kg (11.5 lb) with empty magazine
The Problems: The first production models had stamped sheet metal
receivers. Difficulties were encountered in welding the guide and ejector rails, causing high rejection rates.
http://en.wikipedia.org/wiki/AK-47#cite_note-18 Instead of halting production, a heavy machined receiver was substituted for the sheet metal receiver.
http://en.wikipedia.org/wiki/AK-47#cite_note-Poyer_9-19This was a more costly process, Once manufacturing difficulties had been overcome, a redesigned version designated the
AKM (M for "modernized" or "upgraded"—in Russian: (
Ðвтомат Калашникова Модернизированный [Avtomat Kalashnikova Modernizirovanniy]) was introduced in 1959.
Note: The AK-47 usually handed over to J&k Militia who were using 3O3 for home defense, These AK are manufactured mostly in Afghan villages in Pakistani borders, Like Peshawar, These AK have limited life as the barrel is low graded compare to IA AKMS...
