Looking for an RK-4 or RK-5 vert grip. Prefer new, but used excellent or VG condition is fine as well. Willing to buy or possibly trade for what I need. PM any offers, thanks in advance 👍🏻 😍 1
Not sure if you’ve seen these, but these guys make very nice copies of the RK-4 and 6. Maybe check them out https://dauntlessengineering.com/product/de-4-combloc-style-foregrip-picatinny-base/
