The Harris RotaPod - Rotating bipod adapter - RBA-3 is a great addition to any shooting setup. It allows for a few degrees of swivel from left to right using in conjunction with a Harris Bipod. And, as we know, the game usually doesn't come right up the barrel of your gun, so the adding the ability to swivel to the left or right is a must. The adapter easily installs on most guns, in particular any gun where you can or have mounted a bipod to. It does add a couple of inches in height - so give that some consideration when estimating the height needed with the adapter and bipod together. There is an easy lock handle if you want to lock it into place (no swivel). The unit is made by MIM Manufacturing, and is heavy-duty construction (will last forever). It is on the more expensive side, but a good add to any serious shooter's setup.
