- Bolt release / bolt catch combo button: HK 416A5, Remington RGP, PDQ.
- "Ping pong" bolt release / bolt catches on both sides of lower receiver: LWRC Individual Carbine, S&W M&P 10.
- Bolt release button and mag release/bolt catch combo: AXTS AX556.
- Bolt release/catch at bottom of trigger guard near mag well: Bushmaster BAR-10.
Pretty neat, if you ask me.
