upgrading beuchat mundial carbon 115

[mundial]

hiya hunters

I have decided to upgrade my gun ( beuchat mundial carbon 115 )
I did the following:
Shaft changed from 6.3 mm INOX > to 7 mm hardened Rockwell steel
Shaft wing now goes down instead of the regular up ( SA tip )
Daynima wishbone instead of metal one
I have added a rail for better accuracy
Rubber slings are shortend in 1 cm for more power

I think most guns should come strong and with no need to upgrade them!

how does it shoot after the upgrades? how did it shoot before the upgrades?

 

[mundial]

it shuts better
it is more accurate
more distance
30% more power
most important it is more quiet

Like it. I was going to say "pretty much a Rob Allen Caranx railgun!" but with those wishbone ends & the polymer rail, I'm thinking Rabitech might have provided some inspiration?

Was the bigger spear to balance the 20mm rubbers or was there some other reason for going for the larger diameter?

 

[mundial]

it was the distance that i wanted more
( havier shaft = gets more distance)
hit strike & durability the INOX shaft has broken twice by hitting the rocks
a big enought grouper can damage the thin INOX spear
one friend of mine with the same gun & setup spear a 49 Kilos amberjack!!

Hi mundial,

What is the rail you have used for the Beuchat upgrade?

I have serveral Beuchat guns (75-115cm), but until now I have not found a fitting stick-on rail, e.g. the Omer universal rail's profile is too low for the Mundial.

Cheers, ulysses

JBL Rails suit the Mundial perfectly. I put a rail on my 96cm Elite, made a world of difference.

nice looking gun ^
