    My incredibly expensive solution that has worked for near 60 builds is a 1" wide piece of 1/2" osb wrapped in duct tape- using the same method quib does.

    Simple and it gets the job done......

    Interesting. I've never oiled one. But I move the block a little over so that the guard is resting on it. I do this because of the fact that there is a little play between the guard and the two tabs. Using the bottom tab on the block can cause compression between the two tabs.

    I'm basically tackling one tab at a time. The first tab is impact neutral with the guard on the block under it, and then I move the block behind the bottom tab when the pin gets there. By then, you're pretty much home free.

    A paperback book, folded back to the proper page, works for me.

    Utilizing this method, the bottom triggerguard ear has support from the block of wood, preventing it from snapping off. The top ear is supported by the triggerguard itself, preventing it from snapping off.
    I use the same procedure Quib.
    As a note it also helps to roll the leading edge of some of the roll pins that are sharp or square.This aids in getting the pin started and snag free install.As far as lube on the pin,I use a bit of grease on pretty much everything going into the lower on initial assembly.

    Yup. Another good tip. I've done this assembling AR's, as well as on aircraft components and installs.

    It's amazing how many small mechanical tips or tricks there are that can take the headache out of assembly.

    I haven't had a problem yet with compression of the ears, in my experience the triggerguard seems to fill that space between the receiver ears pretty well. But you have a valid point and that is certainly something to keep in mind.

    This. It works quite well if needed.

    I've found squeezing the pins in with needlenose pliers easier than hammering them in. Thats how I've built the last few lowers.

    I haven't had the problem either, but I always assumed that's how guys were breaking lowers.
