Mags
 

This might be a stupid but I want to learn as much as possible.
high cap=?
real cap=?
mid cap=?

What are the values for the different capacities? Also I read that real cap and mid caps have no feed wheel on the bottom. How do they feed into the guns?

High cap have a feed wheel to mechanically raise the BB's into the gun.

If you are from a paintball background, it's like an upside down hopper.

Real and mid-cap are spring fed like a real magazine, so BB's are fed one by one.

High caps can hold hundreds to even thousands of rounds in the case of box and drum mags.

Real caps hold the same amount as the real-steel equivalent.

This is used for hardcore milsim.

high cap = mag tickler/300+ rounds
mid cap = 100-150 rounds
low cap = 68-90 rounds
real cap = 20-30 rounds or whatever the real steel counterpart carries.

Ahhh...that makes sense now. Cheers.
