In the process of converting my airsoft spring powered to nerf darts, it will still be able to fire airsoft with a barrel insert. Inner barrel is 17/32" K&S brass tubing with 9/16" sliding over that and 1/2" plumbing copper over that, all a perfect fit. First test fire show this has some power, way more than my CedaS it seems, going to get my homemade chrono hooked up again when it's finished. Also added some Drillium.

Got it finished, my homemades chrono shows 140 fps for it and 115 fps for my Ceda S in comparison. To charge and load is two seperate actions but is no problem.

Nice! My Ceda does around 130fps if I recall. Did you check the piston for lubrication? Sometimes they come totally DRY from the factory. Some lithium grease or silicon grease can help. Mine was actually lubricated but I added some extra.

With some lube this is now shooting at 160fps, full length darts will also fit.

Noice- seems ripe for a pump-grip for priming, provided it wasn't too awkward to hook up at both ends.

Tried that with a smaller version and there was too much twisting torque on the handle to get a smooth operation, would need some linear bearings like this one.

The airsoft barrel slides inside the Nerf barrel and clamps at the front, changed the front grip and the charge handle again. Orange muzzle.

Will put a foam dart into single layer corrugated cardboard.
