As someone who has had some amount of play time with both, let me tell you that the problem with the msmc is not one of reliability. Its one of ergonomics. The gun has a terrible weight distribution, and should have been much lighter for the size, Its hard to point up. Nothing impossible, but for sustained periods where exhaustion comes into play, you're going to have troubles.
Its not small/light enough to be fired with one hand at short ranges either.
The mciws is a different ball game alltogether. For one, its not engineered by the ofb, but rather by Alpha tech Ltd., a private firm based out of bangalore i think. Only the barrel is made by the ofb, and is similar to the insas in certain terms. That shouldnt be a problem,because the latter has a beautiful barrel.
I've had to remove my video, as i was contacted by higher ups to take it down.
But as someone who has had a few chances to play around with it. Dont be fooled by its rather simplistic looks.
This gun is more ergonomical than a tavor, and easier to point than an ak.
A the moment of writing, 7 protoypes exist, and a sum total of ~12000 rounds have been fires under range conditions, with problem being due to faulty ammo. THe ia has a sure winner on their hands
