I have a Tavor X95 300 BO, and lost the sight adjustment tool. I emailed them about getting a replacement (paying for it).
The response:
"Hi Charles,
I have some spare sight adjustment tools here, I'll go ahead and send one to you free of charge to the address you provided. If you have any more questions feel free to give us a call!

BTW Taurus went back to lifetime warranties.
