Caliburn Bull Ram

If you have broken more than one Ram2oe, whether due to a slam fire (dropping the bolt sled while open, or a sear failure), or excessive dry firing, try this remix.

The Bull Ram adds about 5mm of print material above the existing Ram2oe screw holes, which consistently broke under the above conditions.

The Bull Ram has been slam fire tested 20 times consecutively with no loosening of the priming arm screws or significant damage to the Ram. Dry firing will not significantly damage the Bull R
