Welcome! sorry to hear about the fall/damage. Looking up that particular model online, it looks to be a standard AR/M4 style rifle. Whilst standardisation in airsoft can be a little hit or miss at times between manufacturers, I would be very surprised if the majority of rail systems sold for M4 style rifles wouldn't fit. The world is your oyster! It is likely that a new rail would come with a different barrel nut too. This is the large (usually cylindrical) nut that slips over the outer barrel, and then screws onto the threads at the front of your guns receiver, thus clamping the outer barrel to the receiver, and providing something for your rail/hand guard to fit to.
Some examples here: https://www.18airsoft.com/collections/rifle-handguard?sort_by=price-descending
You need to be looking for those that are noted as being for AR or M4 type.
