Larry Vickers hinted at the pending limited release of Colt GAU-5/A/A carbines on social media today. Attached File
I anticipate that this will be the fourth release in Colt's 'Military Classics' series. Of interest with this release is the T suffix in the serial number. Some preliminary speculation is that this will be tied to the infamous SonTay prison raid some how.
The previous three releases in the series have been the M4A1 SOCOM (2018 specification), CRM16A1 (Limited to 2500) and the CRXM177E2 (limited to 2500). The CRM16A1 and CRXM177E2 had a V suffix to denote their design affiliation with Vietnam era weapons.
