Swiss Arms Classic Green problem

I don't care what you guy's call that because I call that
Do tell Cyanide Ride, you like or dis-like this set-up. In your view what are the advantages or dis-advantages of having a rig like this?

Thanks Joey (and sorry for the thread hijack sorta)

What I don't like about it:

Not many, but if I had to complain, the mag release is bit of a stretch, thus, needing me to adjust my grip to reach.
With the scope setup, you do need a cheek rest and a riser to clear the stock irons.
With a scope, the front handguard is nearly impossible to get off. (something which I solved by purchasing a B&T carbine rail, it is pricey, but the takedown procedure is MUCH easier than the factory plastic)

The good:
The 556 lower has a much better trigger than the typical SAN rifles, lighter but with the usual takeup.
Readily available cheap mags!
Lots of different adjustable stock options
Length is very handy (I think perfect for me)
It is more accurate than I can currently shoot

In my clumsiness, I shot these two groups at 50 yards:

Do I like it? yes I do.

What do you need to do to your upper to fit a 556 lower?
Mill this part below the charging handle:

Mill this part behind the front takedown pin (the most milling needed)

And the rear fitment for the rear takedown pin needs to be rounded off somewhat:

I bought the gun already setup so I didn't really have to do much more than set it up. This is one of my favorite setups.

Would I buy another one? no, I'd buy a 20" NR and have that milled to fit this lower!

Wouldn't it make more sense to mess with the lower seeing as that is not a controlled part (and made from aluminum)?

Just to go off-topic a bit but ATF won't allow me to import my Swiss Arms rifle into the US because they said the fold in the metal above the bit of metal pictured in the second picture in the above post is an auto sear slot. I kid you not. I tried to explain that it wasn't and the metal was there to prevent someone from trying to install an auto sear and it wasn't a converted automatic but they won't return my calls.

If someone could take the time to apply for a Form 6NIA for their Swiss Arms rifle (with a barrel of more than 16") then I might be able to re-open the conversation with them and get them to change their mind, as they are clearly wrong.

(Note to people who do not understand US import law - temporary imports of these rifles into the US should be okay, they are only prohibited from permanent import under 18 USC 925(d)(3)).

If you want to fix the "Sig Wiggle" as you guys call it, seperate your receiver halves and put the lower in a vice, centered on the front pin/mag catch area where the metal cross/plate is. Squeeze that, then test fit. Squeeze again, test fit. Once you squeeze it enough, you will have NO wiggle. My rifles has absolutely NO wiggle at all. However magazines are a little harder to get in and out (require and bit more force to shove in and pull out), but that's not a big deal. My buddy has done this as well.

I'll keep my wiggle thanks! Looser tolerances are there so that when the rifle is dirty it can still operate correctly. Crushing them out with a vice is not the best idea.
