Steel BBs can ricochet. The shooter and everyone in the shooting area should wear safety glasses when a gun is being handled (even if it's unloaded). Remember to remove all pets from the area- as rebounding ammo can hit them- too. Never shoot steel BBs at hard objects (including metal targets) or water- as that increases the chance of ricochet.

Looks awesome, good balance , very silent and affordable.

Scope is blocking the magazine making it difficult to insert and remove. Very easy to miss and load more than one pellet, clogging the barrel. Design and built to prevent service by the owner. Feed magazine not always go smooth.

By rhettUSAOctober 29, 2017

Great gun for the money. My son loves it, accuracy is ok. But hey, it's a BB gun.. Tons of shots per co2!

By JohnApril 3, 2017

I love the ASG Tac 4.5 except for it's velocity. It loads easily and is very efficient with it's use of gas. I just wish it was a little more powerful.

Loads easily, quality built

Weak velocity

So far this bb repeater has been satisfactory for its intended use. Seems to like Daisy Premium Grade ammunition. Holds an honest two inch grouping at 25 feet. This is not a tight target shooter however, it will not throw rounds all over the intended target. The trigger does not pull real hard and helps you with accuracy. For the price, it is well made and seems like it should withstand normal wear and tear very well.

1. Shot one hundred eighty rounds on one co2 charge. All shots were full power and held on target. When I pulled the co2, there was still a substantial amount of gas left, sufficient to have reached and exceeded two-hundred rounds. Apparently, the non blow-back design promotes excellent use of gas. 2. Reasonably accurate. 3. Nice trigger pull. 4. Good build quality. 5. Has take down capability. Separates at the barrel shroud and the stock making it easy to transport in a compact fashion. No noticeable loss of accuracy after take down and re-assembly. 6. Good balance. 7. The bipod is nice for bench shooting. 7. Affordable. 8. Fun to use.

For the price, I cannot complain or fault this bb repeater.
