- mgc m645 is cyclone barrel （not a rifling barrel）--- 12 indent grooves. --- accuracy is good but low power.
- 六硏 is rifling barrel --- 8 indent groves （simply like realsteel）. --- good accuracy but low power also unless your gun is upgrade to over 「8 banana」.
- still have polygpn barrel and single grove barrel in 90s.
- 6 straight indent grooves barrel for 6mm bb also.
