Wal-Mart guns are what they are. Plastic springers and the odd plastic gearbox AEG that you can use to shoot paper targets and popcans in your basement or yard. They are not game-able.
The main focus of this forum is airsoft as a sport or as collectors of replica guns. Therefore, clearsoft has no place here unless it is a decent clone of a decent airsoft weapon (crosman tri-shot shotgun as TM M3 clone).
