    Engineering shop to mill Stock extensions

    Having spent an afternoon with someone who knows a little bit about shooting it appears I need to lengthen my stocks.

    Anyone know of any engineering shops on the North Shore who could machine something up out of plastic/nylon/whatever?

    Both stocks synthetic.

    I need about 40mm increase.

    4cm is a lot, are you very tall?

    The cheep option is thick plastic cut with a jigsaw then sanded
    You can use anything from a chopping board or 20l containers or anything that's accessible to you

    40mm sounds like a lot to me, never had to lengthen one that much. I use 20 or 25mm clear or bronze acrylic for lengthening a wooden stock, much easier to make a nice unobtrusive job than trying to match a new piece of timber to an original stock. I cut it slightly over size, fit it to the rifle, tape the butt with masking tape, several layers,and then grind to fit using an old shearing grinder. I have the grinder low and a white sheet on the floor so I can look down and see that I'm following the line of the stock. Then you have to fit a bigger butt pad and repeat the exercise. After its all nice and fits well, I use fine sandpaper, or wet and dry to finish it off. If you want to make it even nicer, polish off the acrylic with "brasso" or some similar cutlery type polish and it polishes to clear so you can see right through it.

    The procedure for a synthetic stock is similar, theres a heap of different "plastic" type stuff available from suppliers and you can get black to match the stock. You will need to anchor a 40mm extension firmly to your plastic stock, and that will need a bit of work. Then you fit a larger butt pad to the new piece.

    Routed a spacer out of 25mm Acrylic (I think).

    Feels really good in terms of LOP, but heavy and slightly unbalances rifle.

    Will drill holes through the centre to remove weight, and (possibly) put a better finish on the outside.

    This was reasonably easy as the end of the stock is straight. Bergara is curved, might well try find some one to mill that for me.

    Fitted a 4-12 x 50 Nikko Panamax to it which needed higher rings, got this group at 25m, so getting there slowly.

    The one through the bull may also have been part of the group, can't remember. The other holes were from zeroing the scope.
