I have been reading and looking at all pics about the barrel removal and see that there are 3 springs that surround the barrel.
1 (visible) at the take down push button to remove the reciever from the stock.
1 Visible long spring that surround the barrel and pushes the bolt back and forth.
and 1 ( small not visible ) that I take it surounds the barrel and is covered by the barrell shroud.

My question is about the last small covered spring
What is its purpose and where is it located inside the shroud?

Is it located near the front of the stock where the Shroud starts, or further up towards the flash hider

Also when installing SBR barrel is it reccomended to use Lock tite on the threads of the flash hider
