Interesting 5.7x28 AR upper

[kako911]

I did but you missed it !

Not me! I saw them at SHOT 2008.





You didn't mention the best part.
NO MAG CAP RESTRICTION ON RIMFIRE!

I'd rather have a bolt gun in 5.7... looks like it could be something that would be in the same ballpark as a hornet.

5.7x28 is centerfire.

5.7x28 is centerfire.

Yep, hence my 5 round comment.

Waste of money unless you already have a PS90, and are already stockpiling ammo for SHTF and then unpin the mags.

17 hmr variant would be great.

More ammo in the mags
cheaper ammo price
better availiabily...
and honestly better penetration.

Was that there all along? Damn, distracted by my own photo!

Yeah - these have been out for a couple of years now. Shells eject down through the mag well. Too bad 5.7 is so expensive....

17hmr would be the HEAT!!

Designed a couple of years ago, but only available last fall. I need a lower rear take down pin before I can try mine.

I would prefer a ps90.
How much are they, does anyone owns one?

There are a few in Canada, seem to go for 2500-3000. Can't get any more because the US will not issue an export cert for one.
