None.
Different features than other markers, and durable.
Marker Setup:
GT-2000 w/ ANS Jackhamer LPR. 14" Tru Flight Rifled Barrel and 10" Taso Elimanator Barrel. Ring Trigger and Java Grips.
Recommended Upgrades:
I would buy a Low Pressure Regulator. This will cut recoil, and noise and gain better accuracy.
Strengths:
Dependable, Fast, Accurate even with stock barrel. Use "Zap" paint.
Weaknesses:
Stock grips feel rough. Pull these off and rubber undercoat them.
Review:
1. Start with a LPR. This will give better consistency on this marker. This should be the
first upgrade done. Why 90% of us use Co2. Want more consistency, here it is.
The "ANS Jackhammer 1 or 2 will do, or a "Palmers Rock, etc".
2. Then get a 14" barrel. I would try a carbon fiber or ceramic barrel. Have not tried
these barrels on this marker but know a J&J would kick balls. "aka paintballs".
3. Lighten the trigger springs. Buy a spyder trigger spring kit of the net .
Go to Ace hardware, etc and get lighter springs. If they are a little to long but feel
softer cut them down a bit. This is a cheap way for aftermarket springs. I am
working on a trigger mod for this marker soon. "So check back in a while".
The first mod is the best.
Second a barrel will do athough I am shocked for it being this good stock.
Third I have played pro ball with Micro Cockers, etc. I know about paintball
and knew and played with the Doom Troopers years ago. I play rec ball now.
I have played with all types of markers from PMI, Kingman, WGP, to crap markers
Nelspot and Splatmasters.
When you get good buy a Mag or Cocker. These are the best bang for the buck.
And they have been around for years with a proven track record. Although the GT
2000 will compete with tourney style markers if set up right.
Remember use only Zap paint.
GT+ZAP="NO BREAKAGE".
Conclusion:
Best marker next to a Icon.
One last time very accurate and dependable.
You put a cocker LPR on a blowback as an inline?! Never heard of it being done before...but cool that it worked out. You could also have used a direct Stabilizer...
