New to AR10 need a question answered please

[iSmxtty]

Is there a difference in the size of stocks used on AR 10 and an AR15 I have tried looking up AR10 stocks but keep ending up being offered at 15 stocks. Is there a difference?

Buttstocks are the same but you have two different size tubes, a commercial spec and a mil spec. the commercial is slightly bigger around. make sure what tube you have before you buy.
