Nice addition

Makes this badass gun look even more badass!!!

very solid and well made. I chose to only install one was I felt this would make actual use and penetration much more effective.

Perfectly "Intimidating"

I placed these on the KSG along the the choke adapter and the weapon looks better than the one in the John Wick movie.
Easy installation with fantastic results.
M-CARBO is my "go to" place for upgrades and assistance.

Salt Lake City

Great product. Love the look. Is it needed...who knows...love them personally.

Phoenix, AZ

One spike has terrible chatter/machine marks and looks partially deformed.

I like the concept and functionality of these items. The extensions look nice and feel nice and one of the spikes looks and feels nice but the other has an insane amount of machine marks and looks like a high-schoolers first project. I'm pretty disappointed by it. I also feel like they should have made the spikes flow into the extensions so they don't always look misaligned but that's just a small detail.
