FAQ

Can I use this with MagnaSwitch™ gear?

No, this adapter is only for Disc-Lok™. If you’re running Javelin, SpringBok or Valhalla, you will need the MagnaSwitch™ Q-Sert Adapter.

Will this adapter fit other rifles?

The Q-Sert adapter is only suited to fit rifles with Q-Sert slots like The Fix and Mini Fix from Q.

What makes Disc-Lok™ different from MagnaSwitch™?

Disc-Lok™ is a mechanical locking system with a positive latch. It’s designed as a semi-permanent attachment, which is ideal for users who want their bipod or tripod locked in for a full session. MagnaSwitch™ uses magnetic engagement for quick attachment and detachment.
