The Off Set Arms are two "Extension Arms" arranged in a way to alter the alignment of the Racken Rest II to allow clearance for a Firearm with a large magazine or pistol grip.
They come as a standard length, but can be DIY cut down to size once the suitable length is determined by the user.
This arrangement does not alter the normal use of the Racken Rest II and can be used on the original Racken Rest.
To make this arrangement work, 2 x Extension Arms are required.
