RA-Tech Maple Leaf Precision Hopup Spacer / Tensioner for AEG Hop-up Units

"I tested this nub with an R-hopped PDI 6.01 455mm barrel, lonex aluminum hopup, prometheus flat hop purple bucking, .28g EMG BBs, at ~350FPS.

Measured after a game to see how far my confirmed kills were out to, and the results were about 250 feet. I was not angling my replica to make these shots either.

Tested the same setup with a different nub and the results were similar, but my accuracy was ever so slightly worse. I had a flier every ~50 shots. I can confirm that this nub does in fact make a noticeable difference.

"It gives it a lot of hop for .20s with the bucking the previous owner had on my G&G SCAR, and thats a good thing.

As far as consistency goes, it works fine considering the barrel its in pretty bad shape and with the misterious bucking with a W mound that the owner previouly put in.

So far, im pleased with it, considering that it gives it great consistency on the hop and could hop .32s with ease

"Works and fit great. No issues. I like it better then any other style of nub, including my flat hop. It just makes more sense to me to have a curves nub then anything else. Will buy for all my hop ups
