    Hey guys,
    I'm putting my lpk into a stripped receiver and I had a question that I haven't been able to find an answer for so I hope that you all may be able to help out. When I'm putting the pins and FCG together in the lower is there any special consideration that needs to be given to making sure everything is properly lubricated. I would assume that you should be putting some sort of gun oil or grease in all areas where metal meets metal however most research I've been able to find only relate to oiling the upper and Bcg. Any help to steer me in the right direction would be appreciated!

    Thanks!

    I like to put a drop of lube on the engagement surfaces (sear, disconnector), and to drop some lube on the end of the trigger and hammer holes where the pins will slide thru.

    My Geissele trigger has specific instructions on where to lube, and even came with a small vial of grease to use just for that purpose.

    Haven't had any issues yet.

    I put synthetic motor oil on the pins, hammer and disconector before installation. Here's a pic showing the lubrication points.
