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(TM) 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. SPECS: Mounting System: Q-Sert(TM) Material: Precision machined aluminum Profile: Compact, low-profile design Function: Barricade stop for stability and control Use: Precision shooting, positional shooting, range work
