Upgraded Feed ramp?
 

Do the kwa glocks come with upgraded metal bb feed ramps?

are you talking about the loading nozzle?

If I remember correctly they're exactly like the KSC ones, but even if i'm wrong it only applies to the older glocks (17, 18C and 26/26C IIRC), the 19, 23F and the new vertec glocks should have metal feed ramps installed.

And he's talking about the feed ramp, which breaks because it's made out of plastic on the older models.

Shooters Design makes a reinforced plastic loading ramp for the glock series. You can order it from UNC or WGC
