Great quality! ### ⭐⭐ WORKS, BUT!!!!! *by H***R on Reviewed in the United States on March 10, 2012* I bought the copper john (dead nuts 3 mark iii) sight (6 months ago), only to find out that it does not work right in the first place. The sight and the 3rd axis are somewhat flush but not perfectly. Apparently, this has been an issue with all of the dead nuts sights (I found this out when I took it to a shop yesterday to find out what was wrong with the wind adjustments). When I bought the sight, I took it to a different shop because it seemed like it had to be really tight or it would move around while on the bow (3rd axis and sight do not line up perfectly). This has been determined to be a flaw in the design of the dead nuts 3 sights and a common issue. Now, when you install the windage adjustments, it does not do much justice. The sight bracket and the 3rd axis bracket has to be so tight that, the windage adjustment cannot turn without EXTREME pressure and even then, it does not adjust up and down without loosening the main screw for the 3rd axis with an Allen key (isn't it funny that we buy the wind adjustments to avoid using the Allen keys and to make last second adjustments, and yet, we still need the Allen keys?). It will adjust left to right with extreme pressure and you hear the " Pop, Creak, Crank", noise. I messed with the Allen adjustments on the knobs and it does not matter because the problem is the sight bracket to the 3rd axis and the 3rd axis to the sight. I took it to another shop that I confide in for everything now. He sells the dead nuts 3 (therefore, not as bias as a shop that would not sell it). He said that 3 of his pro shooters (that shoot for his shop) tried it with the SAME ISSUES! They have a dead nuts 3 mark i that they tested and have been trying to sell for a year now. He said they had the same problem. He looked at my sight to check the windage adjustments and said everything was right. It was his conclusion (as well as other people) that it was a design flaw. $103 bucks for the sight (plus shipping, don't remember what I paid for shipping), $10 for the light (15 after shipping), $16 for the light bracket (after shipping), $22 for the adjustment kit (after shipping), and 10 for the 2nd axis (after shipping). So, $166 Dollars plus the shipping of the sight. What an expensive mistake! The sight is durable but, what good is it if it has to be cranked down and ineffective? ### ⭐⭐⭐⭐⭐ Highly recommend *by P***S on Reviewed in the United States on December 9, 2019* Worked perfectly --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.fr/products/5493650-copper-john-dn3-sight-light-bracket](https://www.desertcart.fr/products/5493650-copper-john-dn3-sight-light-bracket) --- *Product available on Desertcart France* *Store origin: FR* *Last updated: 2026-04-23*
