The CDX-40 SHDW action is designed to withstand the extreme needs of military and ELR shooters for the 375 EnABELR, 375/408 CT class of ammunition. With its 1.60” diameter and 10” length, this action can handle the heaviest barrels out there. The bolt features a 3-lug design with an oversized extractor and double ejectors to insure solid lock up and consistent ejections every time. The CDX-40 is designed to feed on a Cadex magazine making for fast follow-up shots at extreme distances. Actions come with a 20 MOA rail secured by 10-32 oversized screws and machined in a recoil lug to prevent any movement. The CDX-40 action is a proprietary Cadex footprint, we do offer CDX-40 bottom metal for traditional stocks as well.
