This rail section will fit the TAC-41 polymer stock :

- SBA-STK-31BK: silverback-airsoft.com/stk-31bk
- SBA-STK-31FDE: silverback-airsoft.com/stk-31fde

It’s mounted on the lateral MLOK slots with 4 Nylon lugs. A rubber pad pushed by a grub screw will help you to adjust the vertical alignment (canceling the free float effect, we suggest mounting the bipod on the tripod mount if you are using this accessory). CNC aviation grade aluminium construction, 155 grams (hardware excluded).

This rail will give you 295 mm of picatinny rail aligned with the receiver rail, and 8 Mlok slots at 45° angle (4 on each side). It will help you to fix any accessories at the front of your scope, typically light amplification for night shooting or scope cam.

Please note you must remove this rail before to attempt a barrel swap.
