Mil-Spec AR buffer weight made of pure tungsten. 130% denser than steel.
Weight: 1.5 oz (41 g)
Normal AR carbine buffer has 3 steel weights inside. Replacing the weights with heavier ones (tungsten) can adjust the felt recoil and cycling speed of your AR rifle.
Heavier the buffer, slower bolt movement.
Instead of buying new buffers you can adjust them at home by replacing the weights.
