Searching for a special use?? - Butler Creek Flip-Open Objective Scope Covers

I was looking for a lens cover for a pro-tac Streamlight m-loc rail light for my AR and after measuring its dia. found a flip-up lens cover from the meriad of covers offered by Optics Planet and this one although rather obscure seemed like it may do the job. They didnt have it in stock but I ordered it any way. After a couple weeks it came back "into stock" and you fowarded it to me express through UPS!! Thats service!! It did fit almost perfectly. I had looked everywhere for something to accomplish this and through your fantastically huge inventory was the perfect jury-rig !! This is why I always go to Optics Planet first So if tou are looking for protection from lead build-up for your lights lens this could work!!Remember though measure twice order once and "OP" will pull through through!!!!Thanks
