Bought czh2003 with vz58 fab defense already attached. I bought wood furniutre to swap it out. Having issues with upper handguard. Took off the heatshield clip. From an installation video, i see its just suppose to slide over but its not. Its very tight and wont budge a bit. Am i missing something? Any help would be apprecaited? Worse case... Anyone local by kitchener area willing to swap for me and can toss a few bucks to.
