    "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

    "Increaded my consistency drastically on my ipgraded vsr10. 100% must have item if youre using the maple leaf bucking and an upgraded hop up chamber.

    "Besides the bucking, this is the most important part of your gun. And this is the best nub on the market. Be sure to glue it to your hopup arm so that it is centered perfectly.
