Murat,
There are 3 type of teak kits u can instal on a MT series.
01. Floater wing, small sweet wing on top of pistol grip
02. The round pizza near the muzzle aka Stab Wing Kit
Both above can be installed on all models.
03. ONLY ON MT-5 Solid Teak Wing Kit, this is like the Blue Water full length wing kit but not laminated teak, so only half the price.
Rig,
I think with the new aluminum muzzle, ur MT4 with 4 x 5/8 band is already in the entry level blue water gun. With ur 3/8" shaft and even with Ice Pick you still can shoot deadly from 18 feet. Just beware of the kick. A pizza wing kit at the muzzle will slow ur vertical aim, horizontal not much effected, it does absorb the muzzle flip in a gun as long as MT4. Floater wing kit (mini), I do not have, so me don't know if it will float ur MT4 when aluminum muzzle installed. If you can get close to 10-12 feet of ur fish, at 4 bands probably you will shoot thru ( enough 4 the ice pick to work ) anything u find in ur water. This I am certain, unless you are after some 250# plus giants.....me can't even imagine that far...ha ha ha ha. Let us know what happened if u mod ur unit.
If luck is on my side, I can tell you something of the mini floater wing kit + aluminum muzzle on an MT#0 early next week. If on an MT#0 it can float the gun w/o shaft, it should do better on MT4 which is supposedly not a sinker with plastic muzzle. However I can not tell you the heavy muzzle effect of aluminum muzzle cause MT#0 is only 81 cm long and at this short length, I think this is a PURE mid handle cause the pistol grip is located some 40-45% from the butt.......must be a dream to handle and swing. Just wish me luck.
