Mid-Cap 140 BB Magazine for LC-3A3 (Plain) Replicas

Solid magazines. I've had no issues with weak springs as previous review mentioned. All my LC3 mags lifts .30g without issue.

These magazines are nice in the sense that they would survive a nuclear attack however they don't feed except for 0.2 g BBs. You need to change the spring in them for heavier BBs. Which is not the easiest procedure, these mags don't have a back door to put the spring in, you need to split the internals and put the spring in from the front while carefully holding the two halfs close to each other.
