Hey Savage Shooters, I just converted my bottom bolt release "trigger guard model" to a top bolt release, with no drilling grinding jury rigging none of that, all I did was change the trigger sear to the top style "it is part of the sear" get this for the grand sum of $12.55, I got it from Numrich I used part # 139590C, there are prefixes all the way though K, I don't know what differences are so, I just went with a model 10 part number.
