Like many others, I was having issues with my Labradar and my 7STW with a muzzle brake. Some have said they have no issues, but I did whether I placed behind the muzzle, in front or even with the muzzle. Not every time, but enough to be a real issue with me. Based on a thread from this site, I called Ryan Cheney at FTW Coatings, Wichita, KS and got on his que for his Quad Pod that he cranks out on his 3D printer. I just got mine last week. Bought a 10 ft section of 1.25" EMT electrical conduit, cut 4 each 24" legs and went to the range. Placed the Labrador on top of the objective lens and shot under the Labradar, set the offset to 18" and went to work. It worked flawlessly on my 40 shots today. If you are having issues with yours, might want to consider putting your name in the que for this device. You won't be sorry for the expenditure.
