My first gun is beuchat hero 110 with roller kit.Haven't tried out invert rollers yet.
For rollers I got several on the list
1. Picasso Cobra Roller 1302. Pathos roller sniper 125
3. salvimar hero 125
4. MVD roller 120
don't know if it is overpowered.
Use in taiwan, for visibility often 10meters or more in the summer time.
any other suggestions for the guns let me know
