+1. I would get rid of this weapon. combat ineffective for close quarters use. if youre sticking with it, fine, but one things for sure: a tightbore, especially a TK twist, is a complete waste of money for this application. You can expect a slight fps increase with it, and you will not notice any difference in terms of accuracy. You want to be spending money on Systema Turbos and deans connectors if this is an indoor gun. Run an 8.4, that should keep the rof down to a reliable level.

No, It's MOST effective at that speed, it doesn't STOP working after it.

yea it does, I had it in one of my pistols that shot inconsistent FPS, when it shot over 330 it did these wierd spirals and went all over the place, under 330 it goes dead center on what im shooting at

Thanks everyone for the help. This is my only gun other then a pistol
Here is what I have gathered so far:
-TM original spring or a 90 spring
-Metal bushings(if it doesn't have it already)
-Prometheus or Systema hop up
-Sorbo pad
-Dynamat installed

Anything else?

you don't need a sorbo pad; the mechbox is strong enough and the only effect will be a duller "pop" noise. If your just using it as a CQB gun, you won't need a new hop-up, the TM one is good enough, and you won't NEED metal bushings, although you may want to install it just in case... Depends if you want to trade of a TM shim finish for metal bushings.

Thanks yuhaoyang for the heads up/tips
