It has been excellent. I wanted something ridiculous and that’s what I got. Almost every time someone new shoots it the first thing they say is “where did it go?!”

I had been looking for an adjustable stock for the C4 for weeks and was extremely grateful to find it here. There were a few things I printed from the set, all worked perfectly. I’ve already downloaded and printed more since yesterday and every piece has worked perfectly so I appreciate it very much.

The team at Frontline Foam are passionate about everything dart blaster and their customer service is evidence of that. They scrambled to get my order out last week and it arrived just in time for my match. Sporting a Frontline Foam Caliburn that day was like being Indiana Jones in the sword scene from Raiders of the Lost Ark (1981).
