Fx Crown from Italy

A questo punto, per aumentare la potenza del fucile, è necessario ottimizzare il flusso d'aria dal serbatoio al pellet, aumentare la pressione del regolatore di pressione e, di conseguenza, appesantire il peso del martello e mettere un molla più robusta. ... Giusto? Le mie domande allora sono queste: meglio comprare un TP in ottone, con doppio foro, da Huma, o per allargare il foro di un TP uguale a quello originale? Calcolando che la mia corona è in cal. 25, il TP di Huma ha i due buchi giusti o devi allargare anche questi? Un altro passo per ottimizzare il flusso d'aria è di lavorare la sonda di spinta del pellet. Qual è la forma migliore da dare alla sonda? Ho letto che alcuni utenti di AGN mettono resina epossidica per chiudere il condotto della sonda di spinta a pellet .... Questo lavoro porta qualche vantaggio?

From your direct experience, on a crown. 25, what can the TP and the pellet push probe work as an increase in power?



Per ora mi fermerò con le domande,

That's very nice work you got there, love to see learn on how you make them, will you be doing a crown stock ?

Yes, within a few weeks I will start a new national solid walnut stock for my FX Crown. I have yet to decide what line it will have ... The presence of the 480 cc tank makes work more difficult and the line is less streamlined.

Good morning to all guys

... A question about the crown. I disassembled all my Crown to proceed with its tuning to increase the power and I found a mechanical detail that surprised me, as I do not understand its usefulness. In the Crown plenum, obtained in the aluminum castle, there is a very long screw that crosses the whole cavity of the plenum. This Allen head screw is screwed into the recess in which the pressure gauge which measures the regulated air pressure is screwed. I tried to remove the screw and then shoot, but the pressure marked by the pressure gauge and the power have not changed.

As I wrote before, I don't understand the usefulness of this seemingly useless screw. Moreover, looking at the exploded view of the crown, there is no trace of this piece. My rifle comes from Spain and a friend (also an Italian) has a crown from Portugal, and both weapons have this long screw inside the regulated air pre-chamber. In words it is difficult to explain everything ... I hope that the photos that I attach explain what I wanted to write. Since there are many Crown owners in Airgun Nation, I would love to have your opinion and if you too have found this "oddity" in your weapon.

The TOP would be a very kind response from FX USA.

Thanks to everyone who will help me solve this "mystery".

This is a still image of a video of Ernest Rowe's disassembly of the Crown ... if you look closely, in his video there is no small allen head of the long screw in the cavity in which the pressure gauge is screwed.
