Dear Guys,
It seems to me that the initial controversy over the adoption of the Type 95 versus the older Type 81 came when the older users tried out the new rifle. Aside from the usual teething problems when you introduce a new piece of ordnance (or any military gear for that matter) there was the fact that at the same time they introduced a new cartridge (the 5.8 mm) to go with it.
What follows is just my humble opinion.
An experienced rifleman, coming from the Type 81 rifle firing the 7.62x39 mm Bloc cartridge will experience relatively weak blast effect during firing due to the following : 1) the intermediate cartridge has less propellant, 2) the Type 81 barrel is longer than its predecessor the AK-47 and, 3) the conventional layout means that the muzzle is farther away from his face.
When that person switches to the Type 95 rifle, he will experience typically more muzzle blast due to: 1) the choice of a magnum cartridge with more propellant, 2) the smaller calibre hence a higher operating pressure, and 3) the bull-pup layout, ensuring that the muzzle is much closer to his face.
As the greater blast effect is a new experience to him, he will probably flinch and this will effect his accuracy and his comfort with the weapon. Also in the bull-pup layout, the distance between the front and rear sights is less than in a conventional layout and as a result, accuracy (over open sights) is typically less.
The advantages of the bull-pup layout is a shorter weapon (invaluable in close quarters like the interior of an APC/IFV) and less weight for the same barrel length. That is you get a more compact weapon, and the weight saved can go into other things like more ammunition, etc.
The choice of a small calibre bullet (the 5.8 mm) would in most circumstances result in improved accuracy as the lighter, smaller bullet would have a flatter trajectory and would generate less recoil. The layout also produces straight-line recoil with less muzzle jump. Unless of course you have soldiers flinching when they shoot. The smaller calibre has another virtue - it is cheaper to make than the larger one.
Like many issues with regards to small arms, taste and individual preference enter into consideration. I believe that when a generation of soldiers with no experience with the Type 81 rifle enter into service, the will find the characteristics of the Type 95 to be perfectly normal.
