all right so kind of continuing on my little refocusing um genre here i'm too cheap to pay for some of the other refocusing devices and a buddy of mine actually sent me a tutorial i already spoke to you guys earlier about how you can turn these butler creek um scope caps into uh simple flip covers for your p this is a mod 3 bravo by the way it's uh essentially it's just you can turn it into two pvs 14s or a bridge tool tube night vision it's kind of irrelevant basically it's a pvs14 uses the same glass so pvs14 whatever other you know uh 18s or anything else really that uses 30 millimeter tubes this will be applicable for anyway i will link the products just in the description of this video you can just grab them on amazon which is a really nice change but um essentially i already have the butler creeks with a small hole drilled in them that i was using for refocus which is awesome but
