- In CF Europe, this weapon, along with Jackhammer-Halloween and Field-Shovel Halloween, was supposed to be added as an RP Capsule in 2011. The capsule, Capsule image and the items of what the capsule contains are still in CF Europe's file, but it was never released due to a last hour Halloween event.
- Also in CF Europe, 2016's Halloween was the year that we saw the release of either M4A1-Halloween and it's capsule. First, the Halloween Creative Event granted a chance to get the weapon who finished 1st and capsules who finished 2nd. And second, the Black Friday sales had the 2011's Halloween RP Capsule in a set for people to buy.
