I have a bergara crest and was wondering if anyone has used the Hawkins featherweight rings on it. I am not exactly sure if I need the mediums or the highs because I have heard different opinions. Also, any reason I should not trust these rings? I would be using most likely a 50mm objective. Also, has anyone changed out the aics for the Hawkins obendorf M5 style kit. I picked one up because I am not a fan of the aics but wanted to see if anyone had any input before I get into it. Thanks
