So it is no secret Griffin is having trouble getting things like the taper mount brakes to market. Rather than spending too much on a device that works/ and is in stock, but is not what I want, I'm hoping some of you could provide the dimensions of the fixed spacer. OD, ID, and most importantly the length. Thank you all in advance. This is just a temporary solution while I wait for a good device for my purposes and will let me shoot my optimus with my 10/22 while they get their manufacturing going. This is not intended as a slam on griffin (41p hurt us all), I'm just looking to not spend $30 + shipping on a simple spacer tube that will cost me a buck of round stock in the lathe.
Thank you all.
