SOCOM Gear Reinforced CO2 Output Valve for SAI BLU ISSC M22 Lonewolf & Compatible Airsoft Gas Blowback Pistols

"So, there's not much to say about this one. It's a valve, It lets air out on demand... It's the only way to replace the green o-ring, which is the part that is the most likely to fail by a long shot. Good that they have this, I guess, what with the magazines it fits in being rather unreliable, espeacially if they're a Co2 newbie's first. Also, I'm not sure what's "reinforced" about it, since it's an OEM replacement.
