GBRS Group

GBRS Group is not currently in stock at Xtreme Tactical. The Hydra mount is bought for one reason — getting a red dot up to a taller sight line on a service-pattern or straight-pull rifle — and these are the live categories that do the same job:

• Red dot sight mounts — risers and plates from co-witness to 1.93 in
• American Defense red dot mounts — quick-detach risers that return to zero
• Rifle scope mounts — one-piece cantilevers and QD levers
• Straight-pull rifle optics — the optics these mounts usually carry

Height is the decision that matters here: see our red dot mount height chart and co-witness heights explained.
