I imagine several folks here have a Swiss K31. I just obtained one late last year and will be getting to the range with it for the first time this coming weekend.
A discussion started in another thread regarding the use of a loop sling with a K31 (which also probably applies to many other older 3/4 or full stock rifles). The forward attachment for a K31 sling is at the 9:00 position on the stock rather than the more customary 6:00. Applying tension to a sling attached this way while shooting is said to torque the barrel and result in unpredictable POI. This seems entirely plausible.
Apparently, some folks refit the sling attachment so it is at the 6:00 position. The claim is that this alleviates or at least reduces the effect of applying force to the stock/barrel via a sling compared to using the 9:00 sling attachment. I fail to see what difference this makes as nothing has changed except the direction in which force is being applied to the barrel. You are still torquing the barrel, right? The torque is just being applied in the vertical rather than horizontal plane.
My understanding is that the Swiss don't use the sling as an assist in steadying the rifle. The rifle was designed such that the receiver/barrel only contacts the stock at three points: the rear of the receiver, the front of the receiver and the front of the stock. The rifle is "tuned" by adjusting the screw at the top of the rear receiver tang. This results in changing the tension (or absence of it) on the stock between the rear of the receiver and the front of the stock; the front of the receiver acting as a "fulcrum" for this tension.
Any K31 experts here with "real world" experience?
