AIM Real Steel M500 Shotgun Top Rail Mount

"I bought this on a whim to see if I could attach a rail to my CYMA metal m870. The curve on the underside of this rail matches pretty closely, however there is not enough space inside the receiver to drill and tap for the included set screws. I used clear JB Weld to attach the rail and so far I am very pleased with the results.

"Bought two of these to attach to my Cyma M870, one to the bottom of the fore-end and the other to the top of receiver. The curved bottom is a pretty close match to the curves of the pieces mentioned. Not shown in listing is that four socket cap allen screws are included as is an allen wrench, with each piece of rail.

Very nicely machined rail.

I've only attached one rail to fore-end so far, with just the provided screws-they 'self-tap' into the nylon nicely if you don't go crazy with a drill.

Receiver rail will be next... :-)
