Techt TPX MRT bolt and Springs?

Timber_Ghost · 12-22-2011, 04:23 PM

How many of you use them? Do you actually see an increase in efficiency? If so, how much?

Also, the Techt website states that you shouldn't use both the springs and the bolt, because the bolt will hit the breech too forcefully. If this is the case, should I go with the bolt or the spring kit to get the best efficiency out of the TPX?

Thanks.

Anyone? I'm interested in also knowing a good barrel to upgrade to. I would really like to try to get 4 magazines off of a 12ie at 270ish.

I use one and my buddy Kirk does as well. I did notice a slight increase in efficiency. He saw a bigger increase, but he chronos at about 260 or so.

I get nearly five off one. I use the springs and if you can use both I would just go with that cause it is so much cheaper. I use the lightest spring that come in the kit. the only time you might run into an issuse where the bolt is better is when you use brittel turny paint. But i have not had any issuse with that.

I'm just using the MRT bolt not the springs. I'm also using a J&J ceramic barrel. in 60° weather I'm getting about 30 shots per 12 gram.
