Does anyone use the boretech action cleaning tool kit who has a zermatt arms origin action? I'm wondering if the molded rubber wiper would break or damage the control feed extractor, especially when pulling it back out since the extractor will catch? Also what size brush do you use to clean your 6.5cm chamber? I really like the boretech idea of cleaning the raceway as well as the recessed lug area with the molded rubber wiper but don't want to spend 75 bucks when it won't work with the controlled feed extractor. Any chamber and lug area cleaning tips would be greatly appreciated. Hope you all had a good Christmas amd new years and got in some shooting.
