I bought this spacer to increase the LOP on an A400 Xplor
As you'd guess, the stock machine screws are too short to pass through the butt plate plus the spacer to an A400 with a KickOff.
The wood screws pictured aren't included and they wouldn't work in this model.
You will need a pair of metric machine screws 18-8, 5mm x 0.8mm x 45mm
It also takes a little reaming with a Dremel,
It works fine and my gun now fits.
Would you recommend this product to a friend?
