Anybody know what size hex key to use to replace the front sight? all of my keys are either to small or to big, I am worried about stripping it or breaking the key being its so small. I bought a green fiber optic off RRAGES but it didn't come with any key to take out the original bolt.  

thanks for helping a noob out

Didn't your rifle come with the little plastic bag with the replacement front sight posts come and an alan wrench in it?  This is from memory, but I'm pretty sure mine came with those items.

Remember, German manufacture....metric screws. The 1.5 mm Allen wrench seems to fit.

Thanks guys, actually after trying like 50 keys I found a star bit that fit.  I had a bag with a key and extra nut in it, but that key didn't fit the one on the sight, anyway problem solved, just took a couple of days of going through all my tools.
