i was thinking of making a BBMG and I was looking at McMaster website and have 2 questions
1. Will 2" pvc rod fit into a 2" plug to be used for a vortex block
2. Will this stainless steel tubing fit a .177 cal bb in it
part # 44635K222
i think it will because the ID is close to the size of a .177 cal bb which is about .25"

1) Yes, it should
2).25 = 1/4"
Where did you get your numbers?

i was just looking at the package of bbs and it says 4.5mm

You should use a 3/16ths" id metal line. 3/16 = 0.1875, it's the closest i think you can get.

You can get it at any local autoparts store, it's brake line. Just cut the end flares off.

It is not that expensive 3ft. of 1/4" brakeline usually costs about 5 bucks where I live.

awesome! i'll start on it once I get all my other projects done like my 2" piston dual chamber cannon, CO2 tennis ball launcher, and backpack mounted spudder. That'll be in a while

Sounds like you have quite a list, good luck on all that.
