McGowen #3 Contour (approximately .705" at muzzle), Recessed crown, 18" Long


I emailed them and asked what the lightest contour would be for a 450 bushmaster. That's what they told me to order. In the order notes I specified I wanted the lightest 450 contour they could come up I with.


It looks like a heavier barrel...but a .45" hole through it doesn't leave much.
