So I was wondering what is the different between a lower bolt and ra tech for mp7s. I want to lower the fps to cqb since its around its 400s. I heard ra tech requires taking many parts of the gun apart then putting them back together where a lower bolt can be replaced quicker.

Also, mp7 cqb bolts are like impossible to find in Canada so the only option would be to order from KWA, but is it legal to order airsoft parts from the US and is it going to cause problems at the boarder with the delivery?

Thank you
