Model: TAC 4.5.
Materials: Plastic with some internal metal parts.
Weight: 3.5 pounds (1588 grams).
Barrel: 12 inches, metal non-rifled.
Propulsion: 12 gram CO2 x 1.
Action: Semi auto, double action only.
Ammunition Type: 4.5mm BB's.
Ammunition Capacity: 21 round metal stick magazine.
FPS: 417.

Trigger Pull: The double action only type trigger pull on the ASG TAC 4.5 CO2 Air Rifle is not too heavy but it is rather long so really quick rapped fire shooting will require some finger work. The trigger reset is right at the begging of the pull so you need to make sure you allow the trigger full range of motion or you may miss the odd shot.

Accuracy: I haven't done my Field Test Shooting video just yet for the ASG TAC 4.5 CO2 Air Rifle but hope to do it soon so stay posted for that video. ASG claimed the fps to be right around 417 but I have a feeling it shoudl come in a little bit higher than this since there is no blowback and the barrel is close to 12 inches long, With the fiber optic front sight and fully adjustable rear peep sight I shoudl be able to get some decent rounds on target downrange and hopefully get a nice grouping.

Build Quality: The ASG TAC 4.5 CO2 Air Rifle is mostly plastic but feels pretty good in the hand with decent fit and finish. There are some metal internal part along with the outer barrel but for the most part the ASG TAC 4.5 CO2 Air Rifle is all plastic including the trigger and front and rear sights.

Realism: The ASG TAC 4.5 CO2 Air Rifle is not a replica of any modern rifle that I know of but it does look a bit like a Beretta CX4 Storm especially the back half of it. The flash hider and top and bottom raise add to the realism.

  • Very customizable with rails top and bottom.

  • Comes with a rather nice Bipod.

  • Front and back Iron sights are very usable.

  • Safety switch is in a great location for right handed shooters.

  • Integrated laser add on is a nice touch.

  • Solid construction.

  • Rubber Butt Pad is nice and thick.

  • Removable barrel to reduce size for easier transportation.

  • Also come in Airsoft version.


  • DOA Trigger pull is a bit long which will slow down rapid fire shooting a bit.

  • Mostly Plastic Polymer build.

  • Why not a longer inner barrel for possible more fps?

It's nice when a new action shooting air rifle comes out on the market since there are not a ton of them. The ASG TAC 4.5 CO2 Air Rifle is a nice addition if you're looking for a BB shooter for plinking around the yard. You can also get an Airsoft firing version too called the ASG TAC 6 CO2 Airsoft Rifle if you want to shoot some rounds that are a little bit less destructive and more game friendly. The ASG TAC 4.5 CO2 Air Rifle offers a lot of customizability with its top and bottom rails for accessories which allow for the placement of the included removable iron sights and Bipod. I would recommend adding a red dot sight and perhaps even a tac light to really dec out this modern looking air rifle.
