Back in January (2005), DefRev published a short article on the recently-introduced DSA Z4-GTC (Gas Trap Carbine). At SHOT Show 2005, we got a chance to view and handle the weapon. Unfortunately, we didn’t get a chance to test fire it. We hope to remedy that soon.

The Z4-GTC is a piston-driven semi-auto carbine in an AR-15/M4 Carbine configuration. It’s the result of a partnership between DSA, Inc. and P.O.F-USA. (Patriot Ordnance Factory, Inc.). The Z4-GTC (Gas Trap Carbine) utilizes the POF-USA P416 w/C.R.O.S ™ (Corrosion Resistant Operating System) gas-piston upper receiver group, which does away with the AR-15/M16’s direct gas-impingement mechanism/operating system, and that system’s inherent problems. The Z4-GTC also makes use of POF-USA’s AR-15 Predator P4X free-float tactical rail system for mounting optics, lasers, tactical white lights, vertical foregrips, etc. DuraCoat finish is optional.
