This is a very good quality rail. The fit and finish are exceptional. Goes on easily and tightens down snug. I have been very impressed with the Monstrum products despite having only recently come upon them. If you're looking for a nice Remington 870 rail, this is it.

Another well built rail from Monstrum. Made of very high quality, high machined aluminum. Looks very OEM. Mounted to my Remington 870 shotgun easily, holes perfectly aligned. My Picatinny accessories fit and hold perfectly. I would recommend this rail to others.
