Great upgrade - Forward Controls Design AR15/AR10 Buffer Retainer

The Forward Controls Design buffer retaining pin is quality made, and the tip is just a little bigger than USGI. I use these in every rifle. The only issue is you can’t use these with the buffer tube with the extended lip and slot cut in it, because it won’t fit. I don’t use those buffer tubes anyway because if the bolt carrier got frozen and couldn’t split the upper and lower, you can’t just unscrew the buffer tube to fix because it will be locked in place. Great upgrade for an item that everyone overlooks.
