JUST FOR FUN I ALSO DID A 0.680 LAPCO FUSE TO COMPARE TO THE 0.691 LAPCO FUSE

About Efficiency:
Comparing the Lapco Fuse in 0.691 (0.695 actual) and the Lapco Fuse in 0.680 (0.683 actual) there is a 15.3 fps difference. It is hard to say which is the exact order of efficiency on these barrels because they are all different bore sizes but it can be estimated with the data here. Just some notes. The Furious does get really good efficiency but not because of the angled porting they claim. It is because it has a much smaller tip than the rest at 0.695" and the porting is much later in the barrel.
If I had to put the efficiency in order I would say:
Best Efficency to Worst:
Lapco Fuse
Disruptive Deathtouch
Furious Lotus
Critical 100g
Dye Ultralite
Macdev Shift
