anyone in vancouver with dremel/rotary tool?
 

Need help filing down buffer tube my approx 2 threads length and mag catch by a few millimeters, please lemme know.

head to kent building supply, talk to one of the employees, see if they have a cut shop. if they do, bring the parts there and have them make the cuts for you (at most will cost like 10$) that will likely be your fastest solution, either that or head to a tool rental shop.
