Good fit, needs instructions - Elftmann Tactical Anti-Rotational, Anti-Walk Pins

These pins are easy to install, but instructions, as noted by another reviewer, are NOT included with the pins, and the website link for the full instructions on the Elfman Tactical website did not function for me. Easy enough to figure out with what could be seen on the main page, but still, would it be too much to ask for a small, folded piece of paper inside the ziplock bag that the pins came in? Jack up the price by a dollar if you have to. It'll pay itself back, trust me.

For me, these pins were purchased to secure a Timney Targa 2-stage inside an Aero Precision M5E1 lower. They fit, but ONLY when I left out one piece of the pin kit. I decided that I would leave out one side's retainer clip. So in total, I have one metal plate and the anti-rattle soft pad on one side, and the other plate and one of two retainer clips on the other. They fit nice and snug, especially when paired with the two set screws in the trigger assembly. I strongly doubt these pins will fall out unless I want them to.

I have given a four out of five mostly for the lack of instructions. That just seems like a silly thing to not include in what is clearly an out-of-the-ordinary trigger pin set that many people will likely be unfamiliar with. The fact that not all parts were utilized in my application is, for me, a non-issue, as the pins are still very secure. My lower receiver is likely thicker than a standard mil-spec AR15 lower receiver in that area. It is already a fact, per Aero Precision, that this lower is thicker at the take-down and pivot pins, so being thicker around the trigger pins would definitely be possible.

Overall, a good buy. When I build my next lower, I will definitely consider another set.

A note to buyers, be VERY careful when you install the retaining clips. Keep a good hold on your screwdriver or you run the risk of scratching up your lower.
