[Hectic]

cant speak of that particular system but i can say all the after market hop ups for our vsr's do that (allow use of aeg barrels) and its a good thing as it opens up a bunch of variety for barrels, prometheus as an example without having to machine it or hunt fot the odd ones that are vsr cut, i know the laylax hop up i have in my vsr is much beter then the stock one.
[I] know the PDI stuff is nice so im sure its a good upgrade.
what other upgrades you have? did you go PDI or laylax? as far as i remember the PDI hop up (the original one i guess) only works with the PDI cylender head and such so just be sure its compatible with what you have alrdy


edit i look at the link so i see it works with the stock cylender head the two sided adjustment will be andy once you get it tuned in correctly but may be more hassel then its worth, i mean if the hop up and barrel are seated straight you shouldnt need this adjustment, i know on the stock hop up sometimes its a lil sloppy (the arm shifts side to side a lil) but once shimmed or changed to the laylax hop up i never had the left or right side fliers

not sure if i like the fact that you havve to use an aeg bucking, tho it does provide options
