I have a Cav MKII lower.  Bought the lower parts kit from a Cav Arms local Dealer off their list.  The Hammer pin and the Trigger pin are the same.  The Hammer pin won't go completely through my Cav!  Isn't the Hammer Pin supposed to fit flush on both sides like the Trigger pin does?  Do I need to find a modified Hammer pin and, if so, where might I find one?  JudoEd

Yes, the hammer pin should be flush just like the trigger pin.  What are you using to push the pin through?

Been using half of a plastic toothpick to push pins through and to seat stuff.  Also works to hold things in place temporarily.

Welcome to the boards.  It's been a while since I looked, but I'm 99.9999% sure that if you read the instruction sheet  that is usually tucked in the buttstock is addresses this issue.

Or you could just look at the CavArms lower and see that the receiver is much thicker around the hammer pin so there's no way for the hammer pin to fit flush on both sides.

My first guess is you're hanging up on the J-pin as you install the hammer pin... It sometimes takes a bit of effort to overcome the J-pin so you might want to save the plastic toothpicks for your next dinner party and use a 5/32" punch and tap it through...

Won the lower in a poker game.  No instructions.  But thanks for saying.

Have seated the Hammer Pin fully so that it is the same depth on both sides.  Just not flush.  Plastic works fine.  Doesn't scratch or dent.  Can drive it into a pine board so is strong enough.  Have used it on other projects.  Cheap and throw away after use!  Appreciate the comments.

Just where it should be.  You should feel the groove on the pin click into place with the J-pin in the hammer.

Ah, I see. I thought that you ment part of the pin was sticking out on one side
