The bezel looks good, but as the assembly received varies from one customer to another, I could try it on my rifle. I received a necklace for 16mm rail, the seller does not specify what size it provides. Some customers receive 16mm, 11mm the other. I contacted the seller, but he says it is impossible to send me the free necklace 11mm, but wants to sell me by Amazon.de 9.99 8.99 + postage. So a little disappointed by the lack of clarity on what is provided. I'll buy a Seben 11mm mounting on sale on Amazon for 10.
