G&G Toptech MP5A5 Handguard?

[rjmcgough 4]

Hi, another question about my Toptech MP5A5. It came with a tactical handguard and after seeing people with the more classic mp5 look (triangular? Handguard) I was thinking of changing it.

 

The problem is the current handguard looks nothing like the ones I am seeing for other brands of MP5.The toptech handguard has an extra bit at the back. Anyone know of a handguard that will fit this gun?

 

I am looking for a normal triangular handguard or the one with an in built flashlight. Don't mind which.

 

Thanks in advance.
