CZ858 Loose Upper Handguard?

[harbl_the_cat]

I'm looking to setup something like this (black one, on top):

But I'm concerned after a high round count that the upper handguard will start to shake loose and thus render any handguard mounted optic useless.

I have the same handguard shown there, and I'm worried since I bent that metal tabs that were originally holding the stock handguards in place, and the only thing that keeps the handguard in place is a tight fight (i.e. friction).

Does anyone have any thoughts on the matter?

I have the same setup. I havent had any problems with it whatsoever so far with fairly high round count. That said, next CZ i get (cant have just one...) im going to go with the NEA system I think.

Its kinda funny but the FAB handguard hold up really well. It is largely a function of the FRN they use, the Nylon absorbs a lot of impact and the fiber reinforcement makes it strong.
