Leupold mark 4 riflescope tenebrax ard for leupold mark 4 mr/t 2.5-8x36 mm, (mpn 62875) - Leupold Mark 4 Rifle Scope / Spotting Scope Tenebraex ARD Anti-Reflection Devices

I purchased one of these ARD's for a Mark 4 MR/T 2.5-8X26, M2, Ill, Model 112633, scope that will go mon MK12 Mod 0 build.The objective lense on these scopes are threaded, but the photo here on OP depicts the ARD as being a snap-on/push-on type ARD. The MPN I purchased for my particular scope was 62875 (36mm). When it arrived it was the correct threaded version. Once screwed on you have approximately 1" that is added to the objective end of the scope. These ARD's do come in a grayish black color that maybe discolored in some sections. However, once you put your flip up cover on (if you choose to) only 1/2" is exposed. The objective flip up cover will be loose and come off easily. What I did was cut 6 1/4"X1/4" strips of black electrical tape and layered them in 3 sections on the end of the ARD then slid my Leupold objective flip cap on and its very tight. If you want it even tighter you add another layer to the 3 sections. With this improvisation the flip cap stays on very tight, will screw the ARD off if you start turning it and I'm still able to utilize my OEM objective flip cap effectively. For me the ARD serves two purposes: 1. it serves its intended purpose as an ARD and as a 1" sunshade (looks cool too). It does add 1" to the end of the scope, so if you purchase a Leupold scope cover get the large model 57868 (larger) instead off the medium 57866. The medium scope cover fits very tight with an ARD and its a pain to get off and on. Leupold makes great scope covers that are slightly thicker than the Scopecoat XP6 models. Lastly, these are very expensive but no one has them cheaper than Optics Planet and you can use a 7% off coupon or ask for a deal and get 10% off with free shipping and no tax depending on your state. I'm pretty happy with the purchase and 10% off and recently purchased a second one for a MK12 Mod 1 build. I hope this review helps someone make a decision on the their purchase.
