Jls rx4 berreta storm

[simonmoore1986]

Just bought this rifle for its unique look (no mocking)
I want to beef up the internals but this will also be my first project gun.

Ive been looking around and and found out he gearbox is similar to the G&G m14 gearbox, so my plan is just to replace all the internals.

Then i would like to replace the motor, if any one can explain the difference between them and what dose better for what (pros and cons) p.s. (not the length i get that bit!)

I then would also like to fit a new hop up and tight bore barrel

I think this is the right one but am unsure as there are two parts to the hop up, the lower attached to the gearbox body and the upper that looks like the tm one.

Also the tight bore, as long it is the same length as the original should it matter about anything else?

Also the stock locking pin is warn and wanted to replace it, ive seen that is supposedly replaceable with a benelli supernova shotgun?

Any info would be great, also for parts there is only zeroone!

Cheers
