Item shipped on time and arrived without issue. The barrel was easy to install and works incredibly well. I paired it with the Orange Mod Works upgrade kit that includes a metal trigger and hammer in addition to an 8kg spring; my Hammershot is now more powerful and the cylinder rotates every time without issue. The included photo is a shot of the front of the blaster after the cylinder has been installed.

The Hammershot kit came in a couple of days ago. I LOVE IT! This upgrade kit from Gavin Fuzzy is well worth the purchase. I appreciate the inclusion of the front axle portion, so I didn’t have to take the original cylinder apart. It went from original to fully upgraded in about 10 minutes. Great kit!

I bought this kit to make my hammer shot worth using. It was very very easy to install, the only problem I came across with mine was, the plastic arm that when you prime the blaster slides and moves the cylinder was too big to slide down the track. I got the Dremel tool out and with slight sanding of the nub to make it small enough to slide down the track behind the cylinder. Other than that it’s an amazing blaster. And if you have read this far, you can double load short darts and it turns it into a pistol shotgun, with the added spring spacer the performance goes back to stock when you use two shot short dart shot gun. I want a 9 shot cylinder for my ultra two now!

This was the first 3d printed item that I have bought for Nerf. After looking at various Youtube reviews, I decided that this was the best option for my Hammershot build. I am really happy with the quality and finish of this cylinder. Dart fit is excellent and it feels solid. Installation was easy and it came with 2 gears, the rotation nub (yay not having to pry the old one off!!!) the cylinder and the spacer. Shipping was all right, but I ordered it before Christmas during Covid so I didn't expect it to get her quickly. I would highly recommend this and am stoked to own one.
