More like baby-proofing.
Don't get me wrong, the Kalashnikov platform is a masterpiece design; that however is more a statement about the army it was to be used for.
The loose tolerances are to make up for an MIC where, due to stalin's unrealistic quota systems, shortcuts were bound to be taken in production. A mechanism designed to operate without the need for in depth maintenance was both to make up for a logistics system that was unlikely to regularly supply necessary maintenance equipment and expendables, as well as retarded conscripts who were likely to have never handled a self-loading gun before.
There is a reason why the Kalashnikov is an evolutionary dead end, and every attempt to have it directly compete with the AR platform or the like fucking fails to catch on; the design has perfectly achieved everything it was intended to be, and that is to be a dead-simple general issue assault rifle. All attempts to meaningfully "modernize" it or specialize it or add on shit generally fails because you are taking a "perfect" design (as in one that has completely achieved the original intention) and make it do things it was never meant to do, which at best results in something imperfect that costs way more than the thing it's trying to imitate.
