Well, I installed my systemA goodies today.Single Piece Metal Hopup: $29.10 US
•Quality: 8/10 - just a few burr lines
•Ease to install: 3/10 - you have to cut up your TM body! WTF! And
the included plastic gears blow, ended up
using my TM ones from the original hopup.
•Gains from Upgrade: 7/10 - I can fire full auto with my mechbox now
Total Score: 6/10 - It is very strong but the installation and
junk parts really ruin it, better be prepared
to do some work...SystemA 6.04 Inner Barrel: $24.50 US
•Quality: 9/10 - Very well polished inside, cutting could be
polished a bit more
•Ease to install: 10/10 - Duh... slide it into your hopup...
•Gains from Upgrade: 9/10 - Nice accuracy, slight FPS gain
Total Score: 9/10 - A very cheap and worthwhile upgrade...
