I have a factory Aimpoint 39mm spacer for sale (screws not included), which can be used with the factory base mount that comes with an Aimpoint T-1 or H-1, or can be used with Aimpoint’s LRP mount. In either case, you will have absolute co-witness with the iron sites.
Paid $70, and selling for $50 shipped via Paypal Friends & Family.
