Yeah but it's a rehash of a MAC 10, A gun with ergonomics worse then any gun in history.

There is another manufacture working on a semi rifle AR style in it though and it will use the FsN magazines.

Is that Excel Arms?

No, Excel Arms is a different company

Excel also has an AR style 5.7 rifle.

Rifle and pistol

Doesn't both of masterpiece arms 5.7 weapons use the fsn mag?

I know one of them does. That info is probably in the other thread previously linked

But it does not use the FsN magazine, it uses a propriety magazine.
This new rifle uses the FsN magazine like their entire line of AR style rifles that use pistol mags.
