Hi guys, these should be ready for order at the end of this week, to ship next week after the Black Friday orders are cleared out.
You can modify a W-3 to use the CTR mag, it's the same procedure, make the magwell rectangular instead of tapered and then swap in our TRG mag catch.
We will continue to make the AICS mag version, the CTR is a limited run for now depending on how well it does. Thank you,
Justin
