Questions & Answers

Bill N : I am confused is this for a Remington 870 or an ar15, I need a Rem. 870 12 gauge receiver extension. It looks correct in the photo however the description talks about it being for a ar15. If this is correct for my 870 and also has a rail built into the bottom of it that would be totally awesome??? thanks for your help.ANDREW R : I'm not sure I understand your question. The manufacturer's website indicates that this image is correct for the model listed. The manufacturer indicates compatibility with AR15 rifles only.
