I was just informed that the CAV15 MK II lowers are no longer being produced!
Upgraded models are in the works!

(from the GWACS Armory home page)

We are thankful for InRange TV’s WWSD project expanding the interest in the GWACS CAV 15 product. With this expanded interest we have virtually sold out of our MK II product line.

This year the CAV-15MKII turns 15 years old and unfortunately during our last production run our injection mold reached its end of life.

We are currently finalizing the design of the CAV-15 MK III that will maintain the same strength and durability as the MK II while including the most requested new features. We have incorporated some features recommended by Russell Phagan aka SinistralRifleman.com who has been involved with the CAV-15 since 2001. These improvements assure the future CAV-15 models are in line with the needs of the modern firearms market.

We will be announcing the availability of the CAV-15 MK III and MK IV later this year!

We want to thank everyone for the enormous support of the GWACS Armory CAV-15 MK II.

Sort of wish I had bought a few more - especially at the price I got these for.
Looking forward to seeing what they do to "improve" them.
