Defiance Machine has a new Deviant Controlled Round Feed (CRF) action for sale. While the CRF is an older style of action made famous on the Mauser, this is a new take on the design. Keep reading for all the details.


Bolt Actions @ TFB:


CRF actions have a cult following among some shooters. Unlike push-feed actions, which push a loose round into the chamber, controlled-feed actions hold the cartridge case with the extractor as it moves from the magazine into the action. This keeps the round from getting lost on its way to the chamber or from “short stroking” the action and jamming a second round into the chamber. This style of action is preferred by dangerous game hunters for that added margin of safety.


Unlike older controlled feed actions, the Deviant CRF is not harmed by single loading and having the extractor snap over the rim while the round is in the chamber. It also incorporates a Winchester-style 3-position safety. The MSRP for the Deviant CRF action is $2,995. It comes in short, medium, and long action lengths and with standard or magnum bolt faces. Head over to the Defiance website to check it out.

From the manufacturer:


"The Deviant CRF is a controlled round feed action designed with a rotating claw extractor that improves the reliability in feed and cartridge extraction when you need it most. Since the round is controlled throughout the cycling of the bolt, there is a reduced chance for feeding failures. Unlike a traditional CRF, however, this action will allow for a cartridge to be single fed into the chamber as well, if the need arises. We built this action for dangerous game hunters and any shooter that needs to ensure proper feeding and ejecting in the highest stress situations. The Deviant CRF is your ideal action when mechanical failure cannot be an option."

    Holy Hell, I like the idea, but for $2995, I would rather sporterize turkish mausers.

    One of the best target rifles I ever owned was a sporterized and converted mauser in .300 Win mag.
