Dan Gregory
Great unit

The only negative thing I have to say is that shipping was on the slow side. Both packages took 3 weeks to Tasmania.

Outstanding slingshot rifle for the experienced hunter

Very tight grouping at 50 yards out.

P. Durham
Very powerful

Went together smoothly, no drama with setup. Well made, but pricey.

Expensive rifle but construction is solid

The slingshot has a lot of power and easily reaches 60 yards+

Thom W.
Best in its class

Consistently impressed with the demon performance. Literally zero complaints after 100's of rounds. It's accurate and super powerful. Devastating at short to medium range.

G. McGuinness
Solid choice for hunting totally worth the purchase

Was easy to get setup and was very close to sighted in right out of the box. Paired the slingshot rifle with a 3-10x42 laser scope

First and foremost, I received the unit it 2 packages. Surprisingly, it arrived from overseas very quickly. Recommend following the assembly video, overall, very straightforward. The GT is very sturdy and well made. I used a small amount lubricant to the bearings inside the main trigger house, which made it glided beautifully. Brad at customer service is amazing. Very quick to respond to emails and he addresses all issues that might arise from owning this beast. I only have 2 issues with GT, the rear shoulder rest is not fully retractable, for easy storage or to carry and there is no way to add a foregrip or handle for better aiming stability. I know the previous model had that capability but was eliminated in the 2023 version. The GT can be customized with scopes and picatinny mounts and accessories. Extremely powerful unit with a ton of potential for hunting and/or fun. I waited for 2 months for it to be back in stock to purchase one. Overall, the GT and the customer service with Brad at HammerSurvival is a win/win for all slingshot aficionados.
