Will be using a 22 inch SS non fluted HBAR contour thread .750 at the gas block. That length should get all the velocity out of the 7mm-08. Dead shot will include installed gas block, gas tube, complete BCG and head space the bolt for $464. Aero Precision M5E1 upper, and handguard and featureless lower will complete the build. Yes I live CA and proposition 13 keeps me here-42 years same house. I have never done this before. Why 7mm-08 Remington? I have over 720 rounds of new Hornady ammo and have not be able to sell it . I do not want to give it away or die and leave it to the wifey. I would welcome any advice, including "don't build that caliber". So, proceed to rip me a new one, I'm all yours.
