    An AR15 is on my wish list, and I will probably purchase one in the next 18 months or so. This was a good walk through. Nice steal.

    I like the piston version better but thats just me.

    What is the lever thing above the trigger?

    They really don't do any thing for most. They are tacticool.

    Not going to find them on my guns.

    Occasionally the hammer or trigger will bind on the pin and cause it to rotate in the frame and wallow out the holes to an egg shape. On precision AR rifles that will affect the trigger pull and cycling speed of the hammer, as well as ruining a good frame.

    The locking style pin locks cut out the possibility of rotation in the frame and any damage that could occur.

    As a side effect, they are also made oversized if needed so that if you already wallowed out a egg shaped hole in the frame you can ream it round and tighten up the whole outfit and possibly restore some of the trigger pull crispness.

    I might consider them if I was using a poly frame, or if I screwed up while drilling a poly frame build.

    But like Batch says, on most guns they are for the taticool affect.

    Looking at the price I see that you can almost buy a new stripped lower for the price of those pins.
