Echo Nine Three has added a Services section to their website. There you will find a growing number of the gunsmithing services that they offer including their CAV-15 Lower Receiver modifications. If you have been reading JTT for a long time, you have seen these services mentioned before several years ago and seen them in use on the Sub 6 with a Twist Build. Now, for the first time ever, these services are officially listed on the Echo Nine Three website which is great because I have received several inquiries about the modifications over the years.
The CAV-15 Receiver Modification package includes cutting the stock to the customer’s specified length of pull, fitting a new butt pad, undercutting the trigger guard, and stippling the grip. If you think about what it would cost to the change the stock and grip on a standard lower receiver, this package is quite reasonably priced and I can testify to the fact the work is very well executed. It completely changes the way the GWACS Armory CAV-15 MKII Receivers handle and goes a long way toward reducing the weight of an already lightweight lower.

The CAV-15 MKII tends to get lumped into the same category as all the other poorly executed polymer lowers and that is truly a shame. These lowers are bull strong, lightweight, and handle very well – especially with the E93 Modification Package. You give up some parts standardization and some ability to easily swap/adjust parts but the price is right and it would take you a few life times to wear one out or break it.
