(adsbygoogle = window.adsbygoogle || []).push({}); When i reset my stats is it only my kdr and w/L that is affected or do i lose any gun unlocks?

Your K/D, W/L, and SPM are affected. Nothing else I believe. (At the bottom of your stats though, people can see your original stats. This only resets what is shown on the "cover" of your stats)

Nope, just your stats.

rank wont change either ,right?

You rank will remain unchanged if you reset your stats.

Adding to partypoker15's post, your accuracy stat will also be reset.
