    thinking of building an SBR upper in 5.56 and was very curious as to the best barrel length for this project and why it is so.

    i have read that the 7" barrels will knock your fillings loose so i was kind of leaning towards the 10" barrel.

    thnx in advance!

    I would recommend 10.5" or longer. Mine is 12"
