I have a SW MP 15-22 Upper Receiver with barrel and forend, no bolt/charging handle. We sent back just the lower, and SW sent an entire gun back. $150 plus actual shipping.
Hi, I'm thinking about purchasing the forend adapter off of mp15-22.com. I want to know whether or not the quad rails of most companies forends will line up after the conversion. I'm assuming they will since the 15-22 is the same size as a regular AR, but would love to hear if anyone has done it.
