Yes but they get loose after 10 shots or so...
A couple of tips for using flats on a frame like this:
1. Use strips of scrap latex or Theraband about 5" long and about .25" wide for fork ties. DON'T USE RUBBERBANDS, they won't hold.
2. Wrap the tie around the fork tip twice before you put the bands on. This gives the band something to hold on to besides slick stainless steel.
3. Wrap really tight!
Follow these tips and you won't have any trouble. Hope this helps!
