Guys,

I have a friend who runs his dad's CNC shop. Things are slow in MI. I pitched the idea of a side fed/paratrooper upper to him yesterday and came up with a list of reasons WHY it would be a good idea:

1) nobody's doing it and it would be wayyyy cool
2) rounds would eject out the magwell and into a brass catcher for reloading
3) lower prone height
4) Shouldn't need an FFL as the recoil spring is in the lower
5) can be made to work with current gas piston conversions if people want them
6) nobody's doing it and it would be wayyyy cool

So, he'd need to come up with a new upper, the parts for the mag release, and a new bolt carrier. I think it's do-able, just can't see why it hasn't been done before.. My guess is it's too much work for most shops who want this kind of product but don't have the ability to do that kind of work. It would look awesome with a PRI carbon tube and ACE stock..... Very WWII ish, but modern!

For the same reason no one has made a top-fed. No one would buy it. What advantage does it confer?

Top fed doesn't work for everyone (lefty's like me), and you'd have to move the gas system to the right side of the reciever... Lot more work to do this.

There have to be advantages to it, or they wouldn't have designed paratrooper subguns that way in WWII.

This isn't about having something "mo' betta", it's about something different. Frankly, I'm staring down another AR build with a pretty ho-hum attitude about it.

You'll notice no one uses that sub-gun design anymore.

If the AR is starting to bore  you, do an FAL build.

Somebody makes a 5.7 AR upper that takes PS90 magazines. It is top fed and ejects out the AR magwell. It is pretty new and I can't for the life of me remember where I saw it, but it does exist.

Where the recoil spring is doesn't matter.
On the FAL, the buffer tube is also on the lower, but the upper is what is considered the firearm.

So what determines it then? The Shrike and 5.7 upper feed from the lower....

I based that statement on BATFE opinions about uppers used for M11/9's where one can get them to fire by pulling the recoil spring back. I know, we're talking open bolt guns, but the only way to get an AR upper to fire is to put something in the bolt carrier and hit it with a rock.

Since I presume Dave is talking about the British Sten SMG, here are a few facts about the Sten:



- The British paras nicknamed it the "Stench" because they had such disdain for it.



- There were very serious binding problems with the side feeding magazine (made worse by the bad habit, which was near universal, of using the mag as a grip while firing).



- The whole design was just an emergency expedient that was adopted and rushed into production because the British had no suitable domestically made sub gun in 1940.



Side feeding magazines were abandoned with very good reason, guys.

None of the engineering that goes into modern firearms design is based on how "cool" the finished product will look.

It would work, but we all know what force cases are flung out of the ejection port. The former magwell would have to be steel lined to keep the lower from getting worn away.

The Sten was disliked for a number of reasons, having poorly engineered magazine interface was one of them. You can't say the same about the Sterling (still in use today in many parts of the world BTW), the Lanchester, the MP28, the FG42 etc.

Maybe I am clueless; if you didn't intend to offend me, you would have just asked if I knew what ATF considers a firearm. Given that other uppers that have their feed mechanisms for AR's and are kosher, I think we're good to go.

But you have a nice day.
