Product reviews for HD-501-580 Barrel Bushing

I just installed one of these along with John's HD-231-S Gov't Model recoil spring guide and USGI Spring Plug. The fit of of the barrel bushing is amazing. My stock one was loose and sloppy and this one feels as if a gunsmith custom fitted it to my barrel/gun. In fact, for the first time ever I needed to use a bushing wrench. The bushing is breaking/settling in very nicely and I'm thrilled with the lockup. I wish I would have done this sooner. I can't wait to see what this does to my groups. Go John! Thank you!
