Lube up and set the Front Site Base.. (FSB)
Measurements - the barrel come in at 15.05mm, the FSB at 15.03.
I would rather have a tighter fit... if only the FSB was 15.01 - 15.02mm
But this is not a big deal.
Set it in with a mallet
Check for linement again. I am really getting to like this laser checking. Its one of the cheap ones but projects a horizontal, vertical and a 90/180/360 degree self leveling projection!!
Remember to place the hydraulic ram on the barrel. We have NOT yet pinned the barrel and the RSB yet!
Now press in the FSB all the way. Check for Cant AGAIN.
Then press in the Gas Block to its final position.
