The double feed DB Alloy has made its first shots!
This uses an unmodified CZ scorpion evo magazine with a specially designed Mac upper and bolt made by myself.
This upper will be able to work with any double feed sub gun magazine out there.

Put together something special for my favorite Mac lower, the DB Alloy!
The engraving was quite the trick to pull off, as was the color. But I think it was worth the work!
You can all get these engraved side plates too!

What lengths would you guys want Mac barrels in other than standard length (5.375")
We are going to be making 5.375 and 16 inch but open to other lengths, let us know!

I think its safe to say our bolt and feed ramps are full semi auto rated. Might take some more practice to get the rhythm down on the binary trigger. But the bolt and feed ramp functioned great!

Hardened stainless steel mac n cheese feed ramps will be an option soon!
Aside from gaining a nice color they are twice as hard as the regular stainless steel ramps. This will further help with wear resistance.

In the beginning we were supplying aves with all of their G17 and G19 front rails, as well as developed the mac bolts they sell. On top of all that

Our shipping is also free rather than 7 extra dollars.

The only thing I want to do is make 3DP guns more accessible for everyone, and since I am a journeyman tool maker I think the best way I can do that is by machining the metal parts we need to assemble these things. That's why I do it.
