TPX Fiberglas Freak Back

Hi,
cause stock Tippmann(A5 Thread) Freak Back´s still don´t work that well i build me a cheap and much better one !!! ;)

Just need for building the form: Fiberglas, Bolt, Breach, Barrelcover, Freak insert(i took a .682) some paper, some tape and use grease for anti stick and fill Areas where you don´t want fiberglas.

I have checked:
The Bolt O-Ring seals in the area before the Little gap between Barrel(Insert) and Breach starts. (I´ve fiberglased without the bumper Bolt O-Ring, so the bolt could move deeper than it ever would do). The bolt would push the ball easely complete into the insert, cause of the form of the bolt tip there is still material behind the O-Ring.

Cause the new Barrel is that nice and short i cut my old cartrige cap(the not adjustable one, cause it´s a TPX) to make the front in one line also it´s looking much better than stock i think !!!

Just Need to fix the look of the front view. ;)

Cause i´ve build me a second one for cocker threads i went on:




Here the 3rd one i´m going build for my TMC(98 Thread) also cause the stock Freak backs for A5 and 98 are ... (cause of the Long way to the insert)

There i got some pics of figure out which is the best Position for the insert in the back. ;)

hammer on pin uncocked Position, not pushed:


hammer pushed, the pin is complete down to valve body:


Insert in ideal Position:




There are three solutions make the bolt fit well into the bolt dive into in area in the Barrel:

1st: Cut a Piece of my .697 insert and put it behind (fits well to bolt O-Ring)
2nd: Use a bigger O-Ring on the Bolt for getting up to the insert Diameter
3rd: Build the back like original and secure the insert on top by a tip

Here the finished pruduct shure not a Beauty but it´s working, which is most important i think ! ;)
