Bolt carrier cam pin

TDP spec cam pins for AR15/M16 bolt carrier, 4340 steel, heat treated with manganese phosphate finish.  What is different about these cam pins, which also explains their lower than average price, is each has been test fired while installed on our phosphated SBCG, they are thus technically used.  We use SCP (SOTAR Cam Pins) on our SBCGs, these perfectly functional cam pins used for test firing became extras. These cam pins are similar to the nitrided SCPs, except they are manganese phosphate coated and do not have the dimple.

SCP, or SOTAR Cam Pin, has a dimple machined on one side of it to help the user reinstall the cam pin in the same direction each time, more info can be found here: https://www.forwardcontrolsdesign.com/SCP-SOTAR-Cam-Pin_p_206.html.
