Mauritius hey? You’ve got a few mates in here then. 
Bienvenue sur le forum, mon ami 
Ok sa fait plaisir d avoir des mauricien
Ah… je ne suis pas Mauricien… je suis Australien. Des Irelandais, en fait… je parle juste un peù Français. 
Mais il y a quelques Mauriciens ici.
ah ok Mellbourne ou Brisbane dans quel ville
Brisbane, matey.
Where the men are men and the canetoads are nervous. 
There are only two states in Australia that have legal gel balling… Queensland and South Australia.
All the other poor buggers miss out, unfortunately. 
Yes i heard even some police chief said that gel blaster could fire real ammunition orvthat we can make real gun with gel blaster fortunately my relatives are in Brisbane Queensland yeah lucky me
Well well still no suggestion for the parts i should buy
I’ve been away for a few days.
35cm barrel, with over 30rps, and over 350fps ay…
31k, 13:1. m110. should be 30-32rps, and will be over 350fps.
Ideally, short stroking, shorter barrel, makes for a more reliable blaster, but you want a 35cm barrel so be sure to run good quality gels, grown well and avoid oversize gels that will may jam. I jammed gel, in a long barrel higher rps setup can be disaster. Pistons will be destroyed. So take care on that front.
Thanks RokSolid ill definitely try that as soon as the parts i need to buy arrives will let you know how it goes thanks again
One more thing considering the gearbox i have by the way its a split one what noozle and t piece should i use and this gearbox perfectly fits the slr receiver i have some slr cylinder head and noozle coming should i use these or another one thanks
Aye and by short stroking you mean removing teeth on the septor gear right
I concur. There’s the problem right there. Be high maintenance that’s for sure sorry haven’t read the rest yet.
Do I need to above my pay grade 
Yes remove teeth from sector gear. You can do the piston to match, but no need to.
Those split boxes, LDT tpiece, nozzle, tappet and head. Always.
JingJi SLR nozzle wont fit the head or tappet plate unless you are using their gearbox.
8mm vs 6mm nozzle tube.
Ok but i am using an slr receiver thats ok to use what you recommanded with this receiver
And i slso receive this it fit the dlr receiver but i font know what parts to use with it
A hammer 
I know bit of a language barrier all ok matey never heard of a dlr before when rok gets time he’ll know
Not dlr but slr heraere humane est
Never had that gearbox here sorry.
SLR receiver fits most gearboxes, and have been great at taking ldt style stuff as a drop in.
but its seems a sturdy one thick and solid can take a lot of beating or so it seems
