S&J hardware AR15/870 CQB system - Help needed

[statixstorm]

Hello,

I'm looking for anyone with the S&J hardware AR15/870 CQB system with the 20.75 inch top rail.

I was hoping someone would have the system and could provide pictures and preferably dimensions for the shim that sits between the stock adapter and the top rail so I can fabricate one myself.

Any help or advice would be greatly appreciated!

Thanks.
