Hi I'm an approved Master Rigger to retrofit Sigma & Vector 3 sport rigs. Retrofit a sigma or a V3 Micron is a Master Rigger work & ONLY a Master rigger who was trained at RWS/UPT can do that. If the Master Rigger is approved by the RWS/UPT he will have the spec. instructions. Retrofit a V3 Micron is an additional training & if a Master rigger is approved to retrofit Sigma h/c it DOES NOT mean he is certify to retrofit V3 sport rigs. Gus, you should not send the spec. sheet that we the approved Master Riggers have to other rigger which you do not know if he is approved for that. The Master Rigger should contact UPT/RWS for that. No other can approve him/her or provide the paper work. Safe Rigging !!!
