    It shipped pretty fast and I’m super happy with the U Caliburn, excelent performance and is by far the most accurate blaster I own. Excelente build quality and service!

    Barrel and ram alignment off by 1-2mm. I don’t recommend U caliburn because we can’t really adjust the alignment much due to the U channels locking every parts into a fix place. After filing the priming bars and screw holes. I can only align horizontal but vertical alignment still off by 0.5mm. Buy a normal caliburn and add the options that helps in rigidity will be much better.

      Yea, ram alignment is a known issue with the U Caliburn. I’ve found making sure the ramscrews are tightened down can help a ton. Also swapping to a machined base can also help the ram drooping problem since the printed bases can wear out.

    I love my U-Caliburn and with a k14 it hits like a truck! Excellent performance (hitting in the 350’s with a k14, brass barrel + ram, and worker gen 2’s) but cumbersome and a bit hard to prime (also because of the k14). If I used another spring like a k25, the prime weight would be perfectly fine. Occasionally, the ram and the barrel misalign when priming as well. If you do decide to gear your U-Caliburn to higher spring loads though (like a k14/k25 + k31), I highly recommend aluminum parts to add durability. If I ran my Caliburn with a regular PLA sear and a k14, I’d be a tiny bit nervous that the intense load on the sear causes it to break and the Caliburn to misfire.

    Definitly love my first U-CaliBurn, running a Turf pro26, 18′ Barrell and Scar hitting over 225fps very accurate. Didn’t had a missalignement yet. Highly recommand the metal parts.
