Okay guys, I apologize for jumping into this discussion. I myself have a V3 and am interested in getting the darn device off my barrel and possibly into one of these mounts. I recognize the benefit of not interfering with barrel harmonics, so you can grab velocity data while also shooting for groups.
So here's my questions, if you buy the V3 and then pay for one of these third party mounts, which seem to be several hundred bucks ($380 in the case of greyopscnc's option). You're well into LabRadar territory. Why not jut just throw down on a LabRadar not fuss with all the corded mess and adaptors?
