I have used them before they were cool when utg lunched the over bore bipod, only in use them in my airforce long guns.. why .. ? That bipod when used appropriately will let the gun move straight back.. when my other bipods let the gun jump been a bit less acurrate.. keep in mind those airforce are doing 170fpe + . Don see no need for a non HP gun to use a over bore bipod.. even in my hp tuned uragans..my Accutac bipods work great.. those utg were in the $130 now they are going in the $170.. still way more affordable that's the joke $500+ Bipod that they are promoting for. The brand of the YouTube Boys.
 
Why ask about
Anyone use a top mounted bipod? Recommendations?
@Believer12 I recommend posing this question in the “All Other Equipment” forum. As for an answer to your question, there is a current thread addressing this very thing. I suggest checking the “Barrels, Moderators, and Devices” forum to locate it.
