Questions & Answers
Will this fit in an AR10 rifle buffer tube (not carbine butter tube) ?? Expert Answer

No, this Guntec USA AR-10 Chrome Car Stock Spring is carbine length and will not fit rifle length tubes. I would recommend the JP Enterprises Tuned And Polished Buffer Spring, found by using the link below:

Chrome spring by SP, Verified Owner, December 28, 2016
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 by 5, Verified Owner, March 10, 2021
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.
