Installation of composite ( plastic ) box

With models that have the receiver/receiver/hardware fit in a box, similar to the situation that is the place to be with models in which the stock and forend are separate. If there is no backlash in the joints of the hardware and the Lodge, this means that at any point in time when a paw shot recoil or the element on the receiver/the receiver will transfer the recoil momentum is always the same in a box and next to the shooter’s shoulder. And still provide the same force/reaction from the hand holding the box over the handguard or of any of the stop under the fore-end (bag, bipod, etc.) on the trunk. Again, if we don’t have a backlash where they’re not supposed to be.

The situation is reversed. Available backlash will increase over time, eventually contribute to mechanical deformation of the joint areas of hardware and lodges until the destruction of the Lodge (sometimes on the first shot), and deformation of metal parts (usually fasteners or subtle elements). It happens in serial rifles (especially those made in our time) the question of the fit of the Lodge is given very little attention or just put a bed without trimming/precipitation, but it’s rare for rifles rifles… how often does this tone come across. But again there is a caveat concerning wood and laminated boxes. It happens that the hardware is sitting properly, but with time again from extremes of humidity and temperature appears fatal gap, or may become loose stocks bolts and the receiver/the receiver will “walk” in the box and wooden/laminate bed pricked.

Again the problem is immediately to do everything right. To properly mount the hardware in our composite box. Backlash/clearance may not be noticeable when trying to push the hardware to the bed of the trunk. The receiver can sit tight in its place, but for example, the gap after the share return will be 3mm. Methods of installation that will be described below, are applicable not only to composites but also to the tree. But because the tree is susceptible to deformation and cracking due to humidity changes and temperature. Because there is no guarantee that the wooden Lodge, so will serve some time.

In the photo the rifle is Remington 700, we see the paw of bestowal and the force vector of the recoil that occurs when firing. Paw needs a maximum of its surface adjacent to the bed.

Photo composite rifle stock Remington 700 which has already made bedding. Ie made a full impression on the receiver.

So well done and bedding of these places, i.e. the trigger guard/triggerguard, it is necessary, if triggerguard stands sideways, shifted etc., because the screws stocks should stand perpendicular to the receiver. The same screws must not touch the walls of their holes in the bed.

In the pictures the walnut bed from CZ557. A dedicated site on which there are traces from the receiver, as if he filled the tree from giving in this place. Although the supplementary support under the paw of the impact is ahead. Should be checked for gaps.

In the pictures the walnut bed from CZ557. Frequently highlighted problem area on the receiver structures of similar geometry. There should be a gap between the iron and the Lodge, and then there are the disjoining force acting on the box. The clearance needed in the composite bed.

In General, the need to fit and place thereof, is dictated by the need to ensure a reliable contact “iron” which “flies” in the opposite direction from the direction of the shot and Lodge/stock, which is the “iron” to hold it. And the contact needs to be the right places depending on the design.

After the share return, and under it, the whole paw glued.

Receiver (receiver) must have full contact to the maximum possible area if possible.

The mounting screws of the stock or of the Lodge must always be tightened to the recommended pressure (check it periodically).
