Got the Kar98 for my brother. It was a slight challenge to put it together but he really enjoyed it.

Great project for my son who loved this piece. Purchasing was very easy and it arrived on time and packaged nicely too!

I built this with my own lego's it worked really well I used the Koenigsegg Jesko technic and Bugatti bolide set's and others to make it, glad I did it works good rubber tension is very excellent! I highly recommend this build thank you.

I'm a Deagle Kit winner of Kevin183's giveaway event. Here's my Real-review of the building kit.

Advantages

1. Bricks included
It's convenient because I don't have to pick out the bricks I need from the bricks I have.

2. Delivery is fast
The tracking of the shipment was quite slower than the actual delivery process, so we were able to receive it much faster than the expected delivery date. I think it's pretty quick in about two weeks for international shipping. Plus, there were no issues during the delivery process.

3. Mechanism rubber bands included
It worked perfectly with the "mechanism rubber band" because I've already confirmed that Kevin183 is working normally. (In my case, I replaced it with my own personal rubber band later.)

4. Brick quality
The quality of the brick was much better than I thought. Some plates and axles are a little stiff, but they have been assembled properly. Also, the lift arm looks rather more durable than the original Lego brick.

5. Friendly service
I contacted Kevin183 about 3 times until delivery because I had an inquiry and he always responded kindly.

Disadvantage

1. There was one missing brick
I had to replace one "LEGO ID: 242001" brick with my brick.

2. Too much force seems to be applied to the trigger part
So I invented a new trigger and replaced it. But I think this problem can be improved later.

Conclusion
Design 10/10
Brick Quality 9.5/10
Delivery 10/10
Service 10/10
Performance 10/10
Durability 9.8/10

I really like this build (everything works) but when I shoot the rubber band and press the trigger the rubber band get stuck on the rod
what do i do
