The peg was a bit small and fits extremely loose into the 5mm holes of every TF figure I tried; Quickslinger, Metalhawk, Voyager Cyclonus, Springer. I had to build it up using epoxy resin. This was the Frosted Ultra detailed, so it might be different with the others. Otherwise, looks great. Made a good back piece for a custom IDW Verity Carlo armor using titan master loudmouth as the base.
