Availability is good: it was in stock at one retailer or another nearly every time we checked in October 2026, but today only Primary Arms has it in stock. It dipped to $18.99 at Primary Arms for a stretch in October 2026, well under its usual $22.99, so sales do come around. Buying today, the lowest price is $18.99 at Primary Arms, which matches the best price we saw in October.

Really like this SBI vertical grip. My wrist feels way more natural on my 16 inch 5.56 build with the mid-length gas system. Mounts up tight to M-LOK, no wobble at all. Only thing is I wish it had a small storage compartment for batteries or a spare bolt, but not a deal breaker.
