Bought this for an AR10 I am building for a client. Hope this works well along with an AR10 buffer I bought. This is the second AR10 I have put together and AR10 spring are much different than AR15. This spring fit the spec's.

Does not fit in S&W MP10. I guess the MP10 is a rifle, not a carbine. My bad.However, the spring's coating was indeed smooth. The tensile spring action was slightly stiffer than my OEM spring and my spring only has about 50 rounds through it.
