Shortening AR handguards?

[Leg]

Does anyone know if it possible to shorten a set of AR handguards and plastic weld the front portion that inserts into the retaining ring back on? I have a short barrel (9.25" tri lug) that I want to keep fairly stock looking and CAR handguards are too long. I need to shorten them to around 4.75". If anyone knows anything about welding plastic, then I'd appreciate your help.

Your best bet is to just buy ( new or used ) the size you need,

Just keep checking the Exchanged forum, they do pop up from time to time,

If I could just buy a set of handguards that would fit then I would, however, they don't so I'm left to seeking alternatives.
