Better than expected!

An absolute must have! Accompanied by the spring upgrade available, this thing is amazing.

Installs like a charm, super worthwhile.

Amazing print quality. Easy to install (I'm a bit of a novice, but I figured it out on the first try). While I love my proud papa, and plan on getting a mighty momma... This just adds to that eco-system.

Nice upgrade

Great part, turned my Fate into something usable. It was very easy to install.
So far, it works great with every LR barrel I've tried. It's great with the Mega XL, in particular.
The only issue is I believe I heard Luke say in a video that it worked as a 3-shot inline clip. Without the sniper barrel, I can only get it work with 2 rounds. With the sniper barrel, it does work with 3 rounds. Not worth deducting a star, since I want to use the sniper barrel anyway, but a little confusing.

I seem to have received the wrong adaptor. I was able to make it work by using a Dremel to shave down the tabs on the barrel, and using a combo of duct tape and Teflon tape on the end I put inside of the breach. It is stable and works well, seeing the other review I am guessing that is the what it is supposed to look like. I use the shotgun barrel as seen in the image and was surprised to find that the spread got tighter when I put the stronger spring in the blaster. I can alter the spread through what darts are used, however it will not get as wide as it would with the stock spring.

I have a 2nd fate and wish to do this mod again, however I want to make sure I get the adaptor that is specifically for the fate. If I leave the 2nd fate with the stock spring than I can use them both and whenever I go to shoot, I have more variability in spread just at the cost of the range and speed of the dart.

To all other customers make sure you know what the product is like instead of impulse buying like me. I heard about this choose to purchase this of the frantz foam as I wouldn't have used each of the barrels and ammo types. I just want to have the fate as a shotgun pistol, so paying for the other barrels was not to my liking.

Adapted for more fun

The adapter fit perfectly in the notches inside the shell and does not even wiggle once installed. This piece replaces the whole front barrel and breech, it is not a barrel insert. The breech is eliminated but it can front load an elite or up to 3 half lengths. Mine fires 2 half's on the second shot. Depending on color choice there is not much orange left. It is so much fun to fire anything I find.
