This barrel band-like attachment for the Hatsan Flash QE provides expanded function of the integral underbarrel Picatinny Rail, allowing side and top mounting of additional accessories around the barrel, toward the end of the grip, while retaining the ability to mount accessories in the underbarrel area.

Full assembly instructions and materials required are provided in the “Instructions and Materials.txt” file.

Assembly requires at-minimum:

• 4 x M3x10 screw
• 4 x M3x12 screw
• 2 x M3x45 or 50 screw
• 10 x M3 hex nuts

A file for an angled foregrip is included, but any foregrip can be attached to the underbarrel slot so long as the screw positions are no wider apart than 3 slots. Should you chose to use the included angled foregrip, 2 x M3x30mm screws and two additional M3 hex nuts are required. The included .3mf version of this file comes with Fuzzy Skin mapping done in PrusaSlicer to improve grip around the front-end. 

Two 40mm x 15mm strips of 5mm foam can also optionally be used to improve attachment clamping force around the barrel and provide an amount of impact dampening.

All picatinny rails in this system provide 3 mounting slot positions. Longer accessories may require longer rails. Included rails are 44.75mm long with a hole spacing of 22.375mm, the holes themselves being 3.2mm in diameter, should you wish to design your own, longer picatinny rails for this system.
