ar15 barrel extension

[heavenIsAlie]

apparently the ones I selected from brownells cant be shipped to canada and the rest of my order shipped before they told me this. where can I get some m4 ramp barrel extensions in canada?

I've sourced some from questar in the past... There are probably not hard to find, it's a pretty common item.... Check with BAdBoyBesson, they make barrels so they should have extensions. See also ATRS and every vendor in the banner above.

iirc they were not very expensive.......

what are your plan, if for use with a SS barrel this will work, if your going to install then parkerise then this will not work will for you
