The IsoTac ThumbHook is our low profile solution for controlling muzzle climb on SBRs and rifle-pattern pistols.
Our ThumbHook can be mounted in a single MLOK slot, at the 3 or 9 o'clock position to be used as a ThumbHook for mitigating recoil and controlling muzzle climb - however the Thumbhook can also be mounted at the 6 o'clock position with the flat side forward to be used as a barricade stop, as a hand stop, or to prevent the support hand from pushing off the forward end.
The size and profile were designed to fit a wide variety of hands without being too large to get in the way.
