It is time for some "can it take a K26?" action!
I was looking for a T-Handle for my Nerf Roundhouse, so I modified shmoey's Charging Handle for the KRONOS.
Because of the upper screw post of the priming grip there was no way to just slide it onto the rival rail of the priming grip. Thus, I split the handle in half and added two more screw posts for M3 screws. You can attach both halfs from the sides and lock them in place by screwing them together. I also replaced the rival rail on top of the charging handle with a picatinny rail.
HARDWARE needed:
3x M3 Nuts.
3x M3 x 30mm screws
To lock the nuts in place I found it helps to take the left side of the handle and tighten the screws in on the nuts so that eventually they are pulled into their posts.
The picatinny design is originally from Captain Slug's Caliburn.
