I have used these with the X-impacts and was satisfied once I learned you have to use epoxy and not insert glue to put them on or they will come off in the target. I almost quit using your arrows because of this problem.

Needed to replace a cracked head on my insert screw so decided to get a dozen and have extra outserts and screws.

This is my experience with the focos pieces-please feel free to let me know if other's have seen/experienced the same. I have seen youtube videos that corroborate. I love the low profile shape of the steel outsert and the lightweight of the aluminum insert. The problem: both break. the aluminum insert is too weak, and for some reason the steel outsert has a tendency to crack at the bottom. Too thin there? Or could you use a stronger steel? of course, if you did, there would still be a problem with the aluminum inserts breaking so I find myself having to use the aluminum outsert and steel insert and it may be the best/strongest combo without being crazy heavy. However, could you make the aluminum outserts less bulky/chunky at all?

Great to have extras on hand. Fit is perfect, just as original.

Product fit perfectly.
