I continue to thank my lucky stars that in the United States one is allowed to “manufacture” their own firearms for personal usage. Without that key provision, many an aspiring firearms enthusiast and designer would be otherwise dissuaded from pursuing innovative designs or personal dreams which in the case of ECCO Machine is a bit of both.

ECCO is a fantastic little shop that uses manual machines to create some intricate little firearms, primarily focusing on rimfire weapons. I’d like to repeat that – ECCO uses manual machines, which is incredibly skill and time-intensive.

Recently, Mark Serbu (of Serbu Firearms) spent some time with ECCO machine taking a look at some of their latest creations. One of the first to be shown off is an ultralight 22 rimfire rifle which TFB has covered previously. Interestingly, the bolt-action 22 is manufactured of ABS plastic which was polished by leather.

However, starting at about 6:34, the “Tease of the Century” was debuted as a mini repeating AR-15. While still a work in progress, the little weapon shows what ECCO is capable of and while not shooting due to minor issues, is a semi-auto work in progress.

Here’s to hoping that ECCO decides to go get a manufacturing license and productize these little wonders!
