Special thanks to Captainslug for the great design. Design used with his permission.
Original Vanguard ram concept by Van James and a portion of sales of the ‘Vanguard’ upgrade will be paid to him.
We’ve modified our Caliburn slightly from Captain Slug’s original to give you better performance. Significant changes include:
– Rambase modified for a tighter fit making for a better airseal
– Plunger and frontbutt modified to be K14 compatible
– Plunger o-ring slot widened for better plunger airseal
– Top railgasm modified to take barrel adapter for tighter barrels
I had Frontline build me a top of the line Caliburn. .509″ ID 18″ barrel, Carbon fiber, Pro26, Aluminum sear, ram, and plunger. This thing is a work of art!
I owned a previous Caliburn, but Frontline’s print quality is considerably better. The finish quality is top notch. The prime is super smooth and there’s no twist or creak to be heard. I’d put this up against anyone’s Caliburn in terms of build quality and finish.
Through the whole process Derrikk and his team were responsive and answered questions and even made updates for me mid order. Build time took ~3 weeks, but I don’t think that’s excessive considering this is an entirely custom build. Build came exactly as I had specified.
My setup with “bamboo” darts is hitting consistently 245-250 fps (darts are getting a bit old), but some as high as 260-280. The seal isn’t quite perfect, but I can clearly hear it leaking from the barrel and ram mate area. So I might just try some different o-rings, but performance really isn’t suffering at all.
Love the blaster! Thanks for a great build!

The Caliburn is the best foam blaster I’ve ever seen. The ability of Frontline Foam to let me choose custom colors for 25+ different pieces of the gun makes them stand out among other sellers. The ability to easily break down the blaster to swap springs for different powers is amazing. I tried the K25+K31 double setup and the half length darts come out of the blaster like lightning. Frontline Foam was very fast with communication and production of my blaster making them again stand out from other sellers. Highly recommend this seller and will watch for future products.
