Hakkotsu M40A3 Internals & Lefty Mod Compatibility

I have read the recent post on modding a sniper rifle for lefties by whisper/TheBauer, and I was simply wondering if this: http://www.redwolfairsoft.com/redwolf/airsoft/Sniper_Rifles_Hakkotsu_Hakkotsu_Hakkotsu_M40A3_Style_Black.htm is compatible. I understand that the mod was made for guns with VSR/BAR 10 type internals. If you can't tell already, I'm a complete newb and only just joined.
