Just replaced the original 1/8" pins with 5/64" on 2006 vintage pMags. The ordinal pins looked fine, but replaced them anyway.

The 5/64" pins are a real PITA. After a few trial and error attempts, this process finally worked - but it was still amazingly hard:
- Trim the 5/64" pin to final length before inserting. Note that for his application, the folks at emag want the both pin legs to go around the castle nut, not one leg bent over the top. Reason provided was accessory case clearance.
- Use a file or Dremmel tool to ease the pin ends.
- Verify the castle nut torque and make sure you get the shaft pin hole center of the castle nut fingers. You will need a helper for this step - and a good strap wrench.
- Carefully bend the pin so that you can get it started. Push in until you get to the bend. Ease the bends as you continue to push it in (various tools are needed BUT DO NOT TAP THE PIN IN).
- Once in bend the legs around the castle nut.

I sent a note to Brad at eMag recommending he make a You Tube video of the process - like Dynon does for autopilot servo sheer pin replacement.

Sharpen the ends so they start through the hole(s) easier.

No, doesn't look like it to me. I have received replacement pins from both E-magair and the slick pins from ACS. The slick ones have one leg that is significantly shortened that I dont think is going to be long enough to secure in the castle nut. The ones from E-mag are significantly longer, and will probably require trimming to aid in installation.

Default Broken Cotter Key

Be VERY careful on how that cotter key is installed into the P-Mag or MAG. As shown, it may come in contact with the case wall behind the ignition. I installed one this way (as shown) and it scratched marks into the case wall, resulting in aluminum particles in the filter. I was told that the cotter key should be wrapped around the hex flats of the nut instead...
