I don't know where you could find one in stock, but different brands/RIS/RAS/regular handguards all have different dimensions of it, so it's not guranteed to fit right in.

that par is not needed on theys models it serves no propuse but i belive you can also get them form ehobby asia and airsoftparts.ca but for the model you have it bears no purpose.

Heres a metal one... http://cgi.ebay.com/King-Arms-REAL-H...QQcmdZViewItem

the problem with king arms ones is that they wont fit tm handguards but hey if its just to make your ris/ras unit look cool then go with king arms!!!!

Wrong, it does serve a purpose. If he had a RAS it wouldn't matter because they are free-floating. But he has a RIS. Notice he has a delta ring assmebly the same as you would with a normal non ris or non ras (just the round hand guard). He does need that item to keep the lower half of the RIS in place.

I used the KA cap for my TM ris/ras and it fits fine with no slop.

ujiro your exactly right! without the part my lower handguard falls off.

If its a TM ris/ras the KA cap will fit, I have the same thing with the lower that comes off. but the upper is mounted with brackets that atach to the outer barrel.
