I use the Beman MFX Real Tree arrows with 100 gr field tips for a total arrow eight of 405 grains. I shoot G5 100 gr broadheads. I must have 20+ arrows and would like to make them a bit heavier plus have a higher FOC %. I tried heavier broadheads but they were not only heavier but larger and just did not fly well.

Is there anything on the market that could be installed inside the arrow from the nock end to make the tip heavier? See my set up below.
