Scopes are great. Iron sights are great. Problem: You can't put both on the same rail.
Well, now you can. These angled wangdoodles turn a short segment of rail 45 degrees, so you can mount a tacticool secondary scope or sights.
I used this in my Caliburn Sniper build, as the scope isn't useful in close and medium range.
I found the regular version perfectly strong and usable, but you may want the flexibility of the split version. Either way, print it on its side for strength.
