This seems to be an issue with U.S. guns so far, not sure about the ones direct from Czech. Whatever monkey was installing the handguard had zero instruction on how to apply Loctite and so they used the adage "more is better" and it is now a huge problem on some of the guns when trying to remove the front hand guard and barrel plates :

This sucks. If you plan to remove the front hand guard for any reason and you are having issues with getting those Torx screws to budge this is most likely the reason....

The US "pistols" are directly from Czech, they are the same thing it is just how it enters the US.

Put it on a drill press and have the drill pressed on the torx driver to prevent slippage. Then manually crank the driver.

When putting them back together, the 4 torx that fasten the receiver to the barrel trunnon need to be torqued equally to 70 in-lb. 50 is no bueno. if they are not torque evenly or torqued with "guesstimation" , there will be issue down the road. You need to break out a torque wrench and make sure all 4 torx click at the same value.

yes, these things are a major pain. Toying with the handguard and the torx should not be a regular exercise. They are not meant to be "operator changeable".

It's the best idea. heat is the best. did you try to loosen red lock tight ever? you probably don't know what is it anyway

This isn't our first trip to the rodeo, lol. Been there, done that. The screws are not the finest quality and because the copious quantities of Loctite have coated the underneath of the countersunk head it has far more grip than you would think. Heat is the trick and what we have been using but it will also discolour aluminum and just generally mess things up. Not every one comes out exactly the same if that makes sense.

End of the day this is just ####e workmanship from CZ. I expected better from an expensive, combat ready rifle. Where the hell is my AR.....) :

I found some screws received a lot of loctite, some screws do not have any at all!!!
 
Mine all came out readily enough with a correct Torx bit and some elbow grease applied to a screwdriver. The amount of Loctite varied with each screw, no rhyme or reason. Definitely worth the effort to install the Prentiss Precision Rail Kit for a proper NATO Military railed "Handguard"...
