ONTOS _ SBL _ Pump Front Grip _ Boom Grip

The cool Boom Grip modified for the ONTOS and SBL.

The picatinny recess going through the whole front grip.
It may also work with other pump-action blasters with a picatinny rail for the pump grip if they are not wider than the ONTOS or SBL.

Thanks to Chance for the file I could use for this remix.
