BudsGunShop.com - Handguard change

Yes. Anything's possible with enough duct tape and JB weld. But what you're describing would be relatively simple, straight forward, and should result in a factory appearance. Good Luck!

Gary - since this is already a free float hand guard, it would be pretty easy to change out. If you get the same brand, you might get away without even loosening the barrel nut. That's "easy peasy".

Gary, yes Sir. The current 9" Diamondback M-LOK Handguard can be switched relatively easily Sir.
