Vector Revisions

I know there have been revisions to the Vector over time to improve functionality and/or reliability. Here's what I am aware of:

• Updated bolt
• Barrel contour
• Barrel updated to chrome lined
• Slider
• Updated fire control group
• Hammer & Spur
• Stock release button
• Ejector block assembly
• Replace a small quantity of out-of-spec ejectors

If you know of others, please chime in.

TDI is now KRISS USA

I'm not exactly sure when in 2010 it happened, but Transformational Defense Industries Inc. has changed their name to KRISS USA.

While on the topic, their Swiss-based parent company Gamma KDG Systems SA has changed their name to KRISS Systems SA.

KRISS Baggage

If you like the KRISS "Super V Covert Carry Case", but don't like your "covert" bag labeled in red with exactly what is inside of it, take a look at the non-branded version from the manufacturer: Tactical Tailor. It's the same 32" bag, but without the embroidery... and it's about $50 less.

Original Magpul Sights

Before using the custom Midwest Industries sights that currently ship with the Vector, KRISS USA had worked with Magpul on a set of flip-up metal sights called the "DC/HM Sight System". These have a bit of a lower profile than the MI sights. Why the change? The MI sights are very high quality and were less expensive than the Magpul. (These are not the polymer "MBUS" that Magpul currently produces for the AR platform.) There is also reference of these original Magpul sights not staying in position very well for some folks. I don't know how many of these were produced for KRISS USA, but they seem to be somewhat scarce. I have seen these for sale "used" now and then ranging from $150 to $325+ on the web. The guys at Milspec Monkey have several pictures of the Magpul sights mounted on the Vector from SHOTSHOW 2008.
