Same idea. Just done better.

The Deluxe Barricade Stop | Small gives you a compact solid contact point for barricades and props now made from aluminum for added strength and durability without unnecessary bulk.

It mounts directly to Q-Sert™ and keeps your rifle from slipping when you’re working positional shots. Small enough to stay out of the way strong enough to hold its ground.

If the polymer version works this just upgrades it.
