Brass catchers

For all the catchers, it applies, that you receive it fresh from the printer and You will have to remove it from the printed protection-shield, drill the bolt holes up from 3.9mm to 4.0mm (unless you want the bolt to thread the holes, that is not recommended). Magnets is 8x3mm (I use these) and You need 4 for the picatinny models and 2 for the receiver models, You can buy them yourself or you can get them from me. Bolts are M4x60mm with a 8x3mm head, they are not included.

Ruger Mk III/IV
It mounts directly on the receiver, with a pair of powerful magnets. It will hold at least 120 22lr casings.

CZ 455
It mounts directly on the receiver, with a pair of powerful magnets. It will hold at least 120 22lr casings.

Picatiny models

Capture you brass in a PET bottle
Capture Your brass in a PET bottle, but with magnets (easy to remove the funnel to clear a malfunction).
Capture Your brass in a bag (not included)
Capture Your brass in bag, but with magnets (again, easier to clear malfunctions, and perhaps just that bit cooler)

This is how You will receive your printed catcher.

Ruger 10/22
Working on it! But there isn’t that much space under most optics for a picatinny mount and the receiver is not magnetic.
