Wouldn't know if all the problems have been rectified or not. If you look at the link I posted above, one user (jonahpach) who had an opportunity to evaluate it over the years, posted his views in page 8
on the recent INSAS model, which is the improved version (Granted that his views may only pertain to the examples he was shown of course).
The rifle was almost brand-new 2010 model black INSAS straight from the factory. Quoting from jonahpach's views:
Fact : 1
Out of the box, the Insas is almost impossible to operate! The police armourer has to use sandpaper on the piston heads as they are very tight and tend to jam on a shoulder at the bottom of the cylinder pipe.
The rifle we tested was practically ‘brand new’ with approximately only about a 100 shots through it. Cocking handle was very stiff and tight. It actually made me feel like I was cocking an airgun! When one manages to actually fully pull back the cocking handle, one has to let go off it suddenly and with a bang otherwise the cartridge in the magazine cannot load properly. (More of this later)
This issue seems to have been around for a while. The same problem was seen when he tested the brown INSAS in 2007 as well. And he's not the only one -- a couple of other articles have also mentioned that the IA armorers often have to disassemble factory rifles and hand finish some parts, to make them work properly. While this problem can be rectified by the end-user (i.e. IA personnel), they shouldn't really have to do this extra work, when the responsibility of manufacturing is with the OFB.
Fact : 2
With the INSAS enemies have to be engaged only beyond 200 meters. The M-16 copy adjustable rear aperture sights is a flip over type and is marked at 200 and 400 meters! I know it is ‘out of the box’ and hopefully the sights can be tweaked. But at 200m adjustment, the foresight is barely visible as tin sheet clamps on the piston cover cannot keep it in place without it bulging out and hiding the line of sight!
Again, sounds like more adjustment issues for the end-user, which should really have been handled by the OFB.
The latest INSAS looks cool.. yup! Switching to black coloured furniture from the orange coloured ones was a good move. What with the modern looking seethrough plastic magazine and dull grey phosphate coating (OFB seems to have mastered phosphating finally) This batch arrived a couple of weeks ago and is fresh from the factory. The finish is much better than the ones I have seen with the BSF and as shown by Cottagecheese. (maybe they read his post, the crude dot matrix type lettering is still there but no more trying to enhance it by rubbing it with paint) The flash hider looks really mean and is probably the best machined part of the rifle. (I bet it is being outsourced)
This seems to agree with what was mentioned in other sources as well: the issues with the original plastic magazine have been resolved and some of the finishing issues as well.
Fact : 4
All spent cartridges are automatically deformed
This is an amazing adaptation! All spent cartridges automatically get deformed thus defeating all ideas of reloading of spent INSAS cartridges. I guess this enables the armed forces to immediatedly sell the spent brass as junk without having to go through the hassles of having to manually deform them by having a road roller go over them. Jokes apart, It looks like the empty cartridge slams against the rear lip of the ejection port thus getting deformed in the process of ejection. This would mean there is a timing fault in the ejection mechanisim. Spent cartridges get thrown 15 – 30 ft. infront of the shooter. Also as can be seen in the photo, the lip of the magazine is too far down and as the mouth of the chamber is devoid of any kind of channel, The armourer claims that cartridges often hit the mouth of the chamber and get deformed thus leadin to loading problems before they enter the chamber.
Sounds like a quality control issue.

Scrap grade cast aluminium Butt plate.. Needs a heavy screwdriver to pry open up the tool recess!
Kinda defeats the purpose of the tool-recess if you need a tool to open it in the first place!
