    Hey all,
    I have a KWA KM4-A1 that I converted to a DMR, and want a better hop up unit such as the Madbull Ultimate Hop (It uses AUG Hop I'm pretty sure)
    I'm pretty handy with a dremel, and need help with where to mill out the lower receiver to accept a 1 piece. Thanks!

    Im not sure on how to do that but ive had better results with my kwa hop up then with a prowin hop up. I know this isnt what you want to do but i would say stick with the kwa and either flat hop or rhop.

    Have you already purchased the Madbull one-piece hop-up? If not I'd stop and look for a two-piece hop-up and save yourself the unneeded headaches. If your cuts or sandings are off, your shots will be effected.

    No, I haven't purchased it yet. Does anyone know of a decent aftermarket 2 Piece Hop up?
