Pros:

• Perfect option for close range engagements and room clearing
• Wider spread compared to the narrow spread of the 40 Mike means good news for you
• Further reach compared to standard airsoft grenade shells
• Muzzle velocity is lower than the 40 mike (it won't hurt as much!)
• Compatible fit in all 40mm airsoft grenade launchers

Cons:

• 10ft diameter blast at 20ft
• 60ft range
• 220 FPS muzzle velocity
• 100 BB capacity

Comments: Built with the same concept of the 40 Mike, the new Master Mike tends to be a bit more comfortable and practical for closer range engagements. It features a much wider spread (10ft spread at 20ft distance) than its predecessor at 220 FPS and comes slightly shorter (93mm length) to fit a wider range of launchers.
