Perfect fix
This works perfectly to make the wobble disappear.

Wobble Reduction
Let's be clear, the shims REDUCE wobble, they don't outright fix it. If your stock is so tight that there is no movement when locked, you will struggle to take it off. Bren 2 requires removal of stock for basic field strip. This means that the stock must have some play otherwise you'll need a small mallet to get it to slide off (ask me how I know). Unfortunately, that's just the design flaw of the Bren and this product does a decent job of reducing the wobbliness, but if you want no wobble whatsoever, forget about toolless disassembly!

Fixed
The Bren 2 stock wobble is one of the few short comings of this incredible pistol. Thankfully this shim kit worked like a charm. Just a bit of trial and error to find the correct combination of shims and the wobble is 100% eliminated both vertically and side-to-side.
