Description
Designed for HPA builds, the Lambda SMART .12 uses a wide-bore 6.12mm design to create a stable air cushion around the BB. This reduces contact inside the barrel, improving shot consistency and long-range accuracy—especially when running heavier BBs. While it requires higher air volume, HPA systems easily compensate, making it an ideal choice for tuned DMR and precision setups where consistency matters most.

- Square cut hopup window suitable for R-hop
