Strike Industries SI-2017 MP5 Thing

Or a possible 3rd option or even more. No one ever imagined option 2 was even an option until the guns were released and everyone gasped.

Well that's true too. The point is that ATF is not likely to allow a HK roller delay pattern firearm that uses a HK lower with a front pushpin without blocking FA function somewhere in the upper receiver. ATF has long held that the front pushpin = MG. Look at the mp5s converted by Vollmer that had a registered sear with the receiver modified into pushpin. The registered sear is forever married to the receiver, because the hole makes the Machinegun. That said, I was very surprised that ATF allowed the MKE/POF in with front pushpin at all. So are there possibly other ways around, absolutely. One possible way is to make bolt rails a different geometry, such that they require a carrier specifically milled to fit and will not accept a FA bolt carrier. Or a carriage block similar to the Swiss SIG 55x which prevents installation of a lower that has the FA sear release lever. Or a much longer shelf behind the pushpin, though ATF has disallowed drilling the hole in the past on guns that have the full shelf. I'm sure there are others. I don't believe these other ways will include a front pushpin without some integral (or welded) block within the upper to preclude FA conversion.

In any event, I wish SI well as this is a cool project.

I'm sure if they write a letter explaining why it should not be allowed, or asking "Is it really true?!?!" they can get BATFE to either:

1) Reject it from the jump
2) Reverse any approval

This is why we have neckbeards actually bracing their neckbeard-brace against the beard of their necks these days. This is why an eccentric brake is considered a suppressor, even with no tube. This is why a forward-mounted magazine holder is zapretov, whether you put your hand on it or not. This is why we have dudes who successfully Form 1'd Machine Guns not too long ago and then called up to see why the BATFE complied with their request and granted the stamp.

This is why it does not pay to innovate.

This is why we are doomed as a nation.

I think that's actually the purpose of the neck beard.

I'd tap that.

The weak link, I see, is the SIG stock.

Not only because everything SIG sucks, but because the comb is too high and it costs $300.

If they just kept inventing parts, and they came up with a 1923 mounted sidefolding stock (or if Stormwerkz made a 1913 mounted version of their excellent hinge), they would own the (dwindling) market for MCX and MPX too...

Looks like a modular mag well. Which is nice.

If it's HK spec it's easily fixed as any K stock would fit including the ones made by B&T.

Yeah, looks like it can use a K stock.

It looks that way, but I doubt you'd get other mags to feed from the HK bolt head.

Yes... I'm sure the usual crowd will wish it took Glock mags, but I don't see that happening.
(Nor do I see the advantage...)

Hahaha... so save $25??

I was thinking more about a 1913-end Stormwerkz hinge + the Manticore stock for ~$150 and you have a much higher quality stock to boot.
