Ratings & Reviews
Very high quality

This is a must for polymer lowers, plus you don't lose 7,814,356 detent and springs as well as breaking 2 fingernails and making your fingers sore trying to install it like mil spec takedown pins, only downsides are it's a bit expensive and it isn't retained so be sure not to lose it, fit is great and very secure, a bit more difficult to use than mil spec pins (after install of course) but not hard by any means.
