Thanks for the reply,
Well again I must say, the gun's price was originally close to 200, neighbouring that of the Broxa and Kraken but was on sale for only 70 (I'm a sucker for deals) so I guess in a barrage of excitement as a cheap person I hastily bought it

(oops?). I found a review of it on ASC and it deemed the gun relatively adequate(?) but I am definitely thinking about touching the internals and modifying it mildly. As for the downgrade of the spring, on Op-For and today's Game Day (for example) the restrictions say 400 for aeg's; is there a reason you recommend this spring replacement?
EDIT: WOW I think I just made a bad buy...apparently the Aftermath Stunt300 is NOT the same as the Lycaon...wow what do I do..N00B move.
