They are not a exact clone. The bolt handle on the Defiance is straight as opposed to the angled handle on the Remington. The bolt handle notch in the stock will have to be extended to the rear to get the Remington action in it. It will have a rather unsightly gap in front of the bolt handle. The bolt release on the Defiance is at the top line of the stock and the stock will have to be cut to accept that as well. It can be made to work, but it won't be perfect.
