The Nitrofin requires some serious milling/filing. Once it is fitted correctly though it is pretty sweet to use.
Hmm. I thought there was some minor fitting with the nitrofin, didn?t think there was milling involved. Do you have experience with trying one out? I?ve Been debating doing a SAO in one of my SP-01s or an S2 for LTD.
