RT Pro and Hyperframe

[Tim Taylor]

I have had a Hyperframe and classic valve combo working great for some time now. I thought I would try the Hyperframe with a LX RT Pro valve I had. I am having quite a challenge getting it to work correctly. I have a no rise body and an am/mm rail with the standard RT on/off. What is strange is that if I make the front and rear rail screws tight I only get about 2 or 3 shots per sec (no barrel leak). As I loosen the rear (and partly the front) screw I am able to shoot faster and faster but there is more and more leak down the barrel. Once I am able to get a good walk on the trigger, the air leaks out so fast that the next thing I know the tank is empty.

I am sure I can get some help from you folks at AO.

Sounds like what is happening is that when the screws are loose the sear is unable to properly catch the bolt, and you are "riding the sear". this can cause all kinds of bad things to happen like worn out sears, chunks being taken from the bolt and a full auto runaway marker. I would keep the screws tight, thats the way it was meant to work.
