    Results: 160ft shooting an A4 sheet. 360FPS

    "I have used this nub in two different guns already. First in a sniper rifle with a standard VSR hopunit, barrel and maple leaf bucking. I have also used it in my Tar-21 Elite version in conjunction with an S-hopped black python barrel and a ryusuko flat hop bucking. Both guns shoot straight and true. The work great with heavy weight BBs. I have a new M4 on the way and will be shopping that barrel with this nub as well. I expect good results.

    Works best with flat hop and S hop builds as far as I have tested.

    Make sure that you have NOT modified your hopup arm for any sort of M nub or eraser nub previously. You WILL need the prongs on the hopup arm for this spacer to be seated properly
