The Accu-Tac BR4 G2 is the smallest version of the Accu-Tac line of bipods. Perfect for airguns and more grounded shots. This guy is no slouch, 100% billet made from the highest quality aircraft aluminum available. It has a quick detach mechanism that attaches to a 1913 picatinny rail, which is not only very secure but also allows you to easily and quickly add or remove the bipod. This G2 model now comes with beefier heavy duty extension legs that will withstand the elements. The Accu-Tac BR4 G2 also incorporates the new lever system that makes adjusting cant that much more pleasant. Adjust and lock the legs independently at either 45 or 90 degrees, forwards or backwards.
