[Guges Mk3]

Because this gun is new and people are still getting there hands on them, I don't know if the upgrades suggested by evike are appropriate.

I would ignore ALL advice from Evike on upgrades. They would sell you a stock barrel under their brand just for no reason other than to "make" money on the uninformed.

For internals I bought:
Prometheus 6.03 EG tight bore inner barrel - length 260mm. (i know it's originally a 255mm barrel, I have a tracer going on it)
Madbull Shark Blue 60 degree Bucking
Modified Baton Ryusoku Hard Bucking

I bought these two buckings just to have and was recommended to use the Modified over the shark, do you guys agree?

Who made those recommendations? Honestly 16 years out of date concerning Madbull Blue and 8 years out of date for Modify Baton Ryusoku. There are simpler more effective options ina Maple Leaf Packing/Rubber/Bucking and nub.

If the hop-up unit is anything like other Krytacs, the nub is going to be an issue. They use a captured nub.

Anyways let's get the meat of the question i'm looking to be answered.

Like all, I want my gun to be shooting further, faster, laser accurate, and further more be reliable where I don't have to be replacing internal parts due to wear and tear, what should I upgrade next if anything?

Upgrade...absolutely NOTHING. We and you don't know what is going inside this AEG. Why replace internal parts sight unseen with stock parts "rebranded" as an "aftermarket" part that may actually downgrade the durability of your AEG?

Quite honestly, You need to use your tool before you consider "any" changes. And by use, I mean 10 plus game days of use.

Changing your AEG even before you have a base line on how it performs makes no sense and is a waste of money.

If you want out of the box accuracy, use heavy weight good medium polish bbs and a good battery (Do NOT buy Tenergy or Titan packs). This will give you a base line on your AEG's performance.

AEG's from good makers last about 120K rounds in "stock" form before issues "may" arise.

If you use it for those 10 days of play and you burn one bag of .25's each day...your only at 25K rounds of use...that is a 3/4 of a year's worth of play.

You seem to be viewing your AEG as a Video Game Gun. I.e. where you snaps in parts A22 and get performance upgrade 50.

It doesn't really work that way. Maple Leaf 60 really means nothing by itself. 60 is the Durometer. But depending on the design it may fit on your barrel and it may not.

60 Super Macaron needs a wide Window to fit and thus work. Of which a stock Prommy will not work. Window is too small.

60 MR, will require a even larger window for this packing simulates R-Hop to 90% effectiveness with slip on simplicity and a larger range of adjustment.

I run 50 durometer because this means the packing is "softer" = more grip => less hop-up dial in => more fps consistency. However, it doesn't always play nice on all platforms with their components.

Couple this with a medium polish bb...my AEG's have little to no dial in to get 75 yard range.

Barrel IMHO is restrictive. I personally run 6.04mm or greater.

A brass barrel is not a bad thing in itself. BB is not supposed to touch the side of the barrel as it travels down it. Krytac barrels are stock 6.05mm (last I heard) and that is a good thing. It allows for flexibility in shooting lumpy bbs to maintain accuracy.

I still reiterate, buy nothing until you field test the AEG over 10 days.

A HT and HS Gear set may not stop over spin...there have been cases with certain HT motors, they still over spin on a HS gear sets. This is mainly due to the spring being so weak (M120).

And yet again, you need an established baseline, without knowing that and throwing in parts...you may think your get a good tune, but the stock tune could have been better.

Barrel window maybe to small.
Nub arm is a capture type.

Krytac Nub and traditional packing.

You can only use legacy split mound packing designs on the Krytac (that is what they use except for captured nub) without "modifications".
