Sako A7 Roughtech

Is there anything I can do to stabilise the forend of the roughtech stock. It's quite flexible, although I don't think it touches the barrel, but there are no open pockets to fill with stock stabiliser like in a tikka lite.

Hi David. Probably best to let Nathan reply for me here. However, Tikka makes an e/z add-on accessory for your fore-end - widening it substantially. I added it and LOVE it. I could very well be wrong but I believe it effectively helps my Roughtech be more accurate. Also added the accessory "grip." Just my .02.

Hi David. If you’re concerned it might be touching, you could smear some grease in the barrel channel, test fire it from all possible field positions, then examine the barrel. It would be easy to sand some material from anywhere it’s touching.

Re: Sako A7 Roughtech
Hi David and others, the following should be noted to avoid confusion.

The Sako A7 Roughtec features a Bell & Carlson stock made from fiberglass with an ali chassis. The chassis runs through the forend.

The Tikka Roughtec features a plastic stock (no chassis) with a 'Bell & Carlson lookalike' finish.

Most stocks will display some measure of flexing, even with a good degree of reinforcing, simply due to the very long area. Provided the stock does not contact the barrel, the main issue with flexing is that it can place the system under stress somewhat like a drawn bow limb, having a detrimental effect on accuracy due to differences in stress from shot to shot.

The simple fix, is to try to not place the system under stress - i.e., when shooting prone in the field - use a backpack, not a bipod.

But of course many of us would still prefer to minimize any potential issues regardless of how the rifle is rested when shooting.

If the stock is hollow plastic, I would normally recommend stabilizing but as I have stated in the stabilizing instructions, a main function of this is to provide a bedding surface so that one can apply bedding compound which then ties everything in. Bedding is the key.

David, your glass stock does not need any filling. It is also rigid enough for accurate shooting as is, provided it is not used with a bipod. The flexing is besides the point anyway, the rifle is relatively light and a bipod will simply create more bounce, regardless of forend stress.

You could set about bedding the rifle if you really want to. Bedding 1 inch into the barrel channel will remove most of the flex and likely improve accuracy as a result of the superior receiver fit. Having said this, you must understand that bedding the A7 B&C stock is rather complicated (I believe I wrote about this in Rifles - second edition), requiring removal of some of the chassis material. You must therefore decide how much you like this rifle. If it is a true pet rig that you absolutely enjoy walking with and shooting then sure, it may be worth putting time into it, But if on the other hand it is merely an OK rifle, perhaps lacking in magazine length (for hand loading), then most definitely leave it as is.

Hope that helps a bit.

Re: Sako A7 Roughtech
Thanks for the replies.
I like the rifle. It's easy to carry and shows potential at the range. It's in 308W and the way the gun laws are going in WA it's going to be too difficult to replace. So I guess that makes it a keeper.
So far it seems to like 150gr pills, but that may well be me not controlling the recoil with heavier loads. I still have work to do on my technique.
I might go to the effort of bedding and dropping in a recoil lug, aka, tikka style. I've successfully bedded a couple of tikkas and think I have my head around the surgery required on the Sako roughtec stock to achieve it.
Thanks all. Davo.
