True, the SPG (Tactical Rifles' Special Purpose Grendel) looks the part, but does it do the job?  In a word, yes.  It functioned exactly as intended by consistently and repeatedly putting accurate hits on the target.  Tactical Rifles.net guarantees the SPG (like all of its precision rifles) to deliver 3-shot, .5-inch groups at 100 yards with factory ammunition.  My test rifle more than fulfilled that claim (three-shot groups ran in the .30-inch range) and, when I did my part, the rifle was capable of putting five shots inside that .5-inch mark.  Having tested several Tactical Rifles’ products recently, I expect this level of accuracy, but let us not forget this is a semi-automatic rifle with numerous moving parts, not a precision turn bolt.

"Besides being accurate, the SPG was also quite shootable.  It was the only rifle I’ve ever test fired that shot better groups from a bipod than a sandbag rest.  Since a bipod is undoubtedly the way this rifle would be deployed in the field, it’s great news for the user.  Recoil was virtually non-existent, resulting in a video-game-like experience of pulling the trigger and watching rounds hit the target.  Using the Nightforce Velocity reticle, hits on steel discs at 500 yards were as simple as choosing the correct aiming point and squeezing the trigger." -Keith Wood, Shooting Illustrated
