Hey there. Just joined this forum hoping to gain some knowledge. I'm changing up my 10/22 to tactical style. Been looking for a bull barrel for it and keep coming up with "Out of Stock" every where I look. I've checked Tactical Innovations, Midway USA, Green Mountain and all are OUT OF STOCK. Anyone know why? Is this mod that popular that they can't keep them in stock? Anyone have any recommendations? Thanks for helping a newb.
