ah another question on mag barrels

[zacbot]

do they come with the nubbin and the orings pre installed?

[Head knight of Ni]

mine didn't I had to put the o-rings on and the nubbin they were in a little bag with the barrel.

[zacbot]

koay so they are their, but i have to install them and calibrate them/

[Head knight of Ni]

I just threw 'em on and slid the barrel on but I did have the nubbin pushing one oring up which jammed the barrel in there. So get proper nubbin placement and just twist n' lock.

I have a question about twist lock. If you have level ten and twist lock do you have to adjust the level ten for each barrel or doesn't it go in that far or make enough of a difference?
