getting all the parts together to send my barrel in for a pin/weld, and I know I need the barrel nut and gas block on prior to the pin/weld , my question is do you want the flash hider already tightened and timed or do you prefer it loose when its shipped to you?  other items will already be on of course.....


thank you

Doug Hunt

Doesn't matter, we have to remove it to drill it anyhow.

thanks for the quick reply, loose it is...
