Don't know if anyone has come up with this before but I have had problems with my rifle falling over while I'm out shooting - waiting for Squizzers can sometimes take an hour or so and the easiest thing I find to do with my rifle is lean it against a tree - but several times my gun has fallen over and then I have needed to disturb the peace by checking zero. After a little thought I tried putting an O ring over the silencer/mod, about 1/2" from the muzzle - get a thickish one with an I.D. about 2mm smaller than your silencer dia. and push/twist it on....problem solved the O ring almost sticks to the tree...so simple. Hope this is of some help to someone
