Probably one of the most overlooked advantages of the AR-15 in law enforcement is the entirely inline system, where axis of the bolt carrier, buffer and recoil system goes directly to the area where the carbine mounts on the shoulder. When a shooter puts the hearing protection on and fires a few rounds downrange with a carbine, there is a distinctive captured spring sound as the buffer is forced down the stock tube. I can only describe firing the TR-15 in an intangible way: It seemed to cycle smoother than its mass-produced counterpart.
Thor Global Defense Group recommends a tactical latch as an upgrade to the basic model. We would add the GG&G-1006T MAD Flip Up Rear Sight with Tritium, a low-profile flip up rear sight, a Leupold Mark 4 1–3x14mm CQ/T scope and a 5.11 Tactical VTAC 2 point sling. This combination would cover all potential shooting situations for a tactical carbine.
Overall the TR-15 was … well … boring. That is, the rifle did what Thor said it would and didn't do what it said it wouldn't. This is a testament for a carbine that is available in the individual officer-purchase price range.
Why do I recommend the product? Simple: Vested interest. Thor Global Defense Group does for a living what we want a firearms manufacturer to do: it uses its gun. This is akin to a climbing rope manufacturer using its products on company expeditions. Does anyone think they will use lowest bidder parts?
