Well I think that this statement is absurd!
Let’s think of a Parker Hale L82 (C3) sniper rifle, their mount has 4 very small bolts that are attached to the receiver which is 3mm thick!!
So peter are you saying that these rifles are badly engineered (I don’t think so) they give suburb service to Australia, New Zealand and Canada
.
I do agree about the Pecar scope the ZF69 was the pick of the lot.
