Fantastic upgrade! I have a Mav88 with standard wall thickness barrel. As I expected I had to sand down the bottom of the new bead sight a little and it took me a little longer than Dawson shows in the vid as I needed to remove a little more for the thinner Mav barrel, but I used 320 grit paper too so a lot finer than what he uses in the vid. Finished with 1200 grit too, then polished the bottom of it as well. Im a perfectionist, which doesnt help. Not a problem though I like everything to be just right, so no one else needs to go to this extent :o) Have a bad neck injury at present, so wont be at the range to try it out for quite a while, but it is a WHOLE lot better to look at down the barrel at this than the standard bead. Used a long straight edge and the bottom of the ball lines up perfectly with the line of sight looking down along the top of the receiver. Its going to work brilliantly. Cant wait to see the difference in the field I have no doubt it will really help compared to the standard factory smaller and lower height bead causing high shots. The Defender Tactical one is a lot easier to see as well with my nearly 60 year old eyes. Thanks again Wesley and Dawson !
