Ok. Here it is.........
This comes right From the Carl Walther Gmbh company post. I will copy paste and then follow up with the link if interested. Gmbh is German for German Private Owned Company. This is the information for the Colt M16 SPR . I do not know about the other versions as this post is for the SPR. And here it is copy paste. I only copy paste a small portion. To get the full post, visit the Carl Walther Gmbh site with the link provided. I did not want to violate any of the Walther German copyright laws by copy pasting the page. Not sure it would anyway since it has to be for gain. but .. anyway.. Here is a small portion...
Colt M16 SPR Rifle , Under the brand name COLT the legendary models of the COLT M4/ M16 series are produced in Germany by CARL WALTHER in caliber .22 l.r. in TOP quality. Same as on the original the upper and lower receiver is made of high-quality aluminum as well as the milled Pica tinny-style rails of the different fore-end variants.
All variants are supplied with a 30-round magazine as standard. According to the different national laws 10-round or 2-round magazines are available, too.

■ Tactical Railing: Made of CNC machined high-grade aluminum to accommodate a wide variety of tactical accessories with Pica tinny-style mounts.
■ Safety: External, manual safety for safer handling during inactivity
■ Sights: Flip-up front and rear sights, adjustments for windage and elevation

This is straight from the Carl Walther Gmbh site. This is admission that Walther does make this weapon. Since I go to Germany every year, I will swing by the plant and Visit with Carl Jr then next time I am there and double check that these are not copied in Violation of Copyrights and Patents from Carl. The Germans do take offense to those that would use their name without written authorization. My take is that there is in no way any of these models made anywhere except in Germany by Walther. I will check other Walter Models for the ULM or NEU ULM stamp on metal as I have not heard this before. But now that I own one, I will research it more and let you all know. Here is the link to the Carl Walther Gmbh page for this weapon.

Note at the very bottom of the page... Since I did not copy paste in whole the content. Only a part. This should be fine.
