M203 compatible rail system

[Clay82]

Could anyone tell me which rails that are compatible with the M203?
It would be better if pictures are also shown.

Thanks!

We attached the M203 to the M4 Barrels with KAC rails with no problems, all you do is leave off the bottom rail and attach the 203 first.

For the US military-Knights Armament RIS and RAS railed handguards. LMT makes an adapter so you can basically mount that M203 on almost any railed firearm. Look here: http://lmgtfy.com/?q=M203

LMT and KAC make 203s that are mounted directly to the rail, but the military's legacy 203s in inventory have the bottom rail removed and they're attached conventionally, like before M4s and 16s had rails on them.
