Note that these sales are for the software only.
 
The pictures are examples and they tell you which parts you need to build the devices.  The software is sold compiled and any buyer needs to run some scripts in advance to provide the seller with internal codes to enable the software to be compiled to match your hardware.
 
Fair play to the seller, but it’s a small market.  A reasonably technical person could build and code their own devices, and there is open source code and demos there for free - the seller is marketing their game modes and device design 
 
We build our own, with our tech guy building professional standard ones and me experimenting with less professional ones …… (and ours aren’t for sale, as they are designed around our game modes for our events)

If moving parts are lighte, with the same air pressure / chamber capacity pushing a standard weight vs pushing a lighter weight will have less resistance
To maintain equal muzzle velocity the air pressure ought to be dialled down if ‘lighter’ / more efficient parts are fitted 
 
If effect you’re giving a light puff on standard parts and a harder blow on lighter parts
 
 
Classifieds item descriptions from sellers may also be very subject to ‘buyer beware’
 
 

400fps?  This is not useable at any UK site and, if it retains the full auto function, is no longer classified as an airsoft weapon but as a firearm.

104-108 is for chest size 104cm to 108cm, and V-VI for long arms

Not a question but a comment - often generally called a Dish Dash, but may be a thobe

A ‘soldering gun’ differs from a ‘soldering iron’
 
I’m no expert, but a soldering gun runs hotter than an iron

Could you post up extra pictures of the date & standards markings .....
eg manufactured / born date, expiry / death date, any test stickers, and the DOT/TC/Pi or ISO standards approval markings 

Why £299 friends & family as opposed to £310 fully PayPal’d
 
F&F has no fees involved and no protection
Standard PayPal pays for their service and protects the buyer from you. £300 is a fair whack to send across the internet with no protection 
Assuming you are not a con artist your terms look like you are afraid of comeback from buyers 
 
 
PayPal accepted, but ONLY as “Friends & Family” option selected. Otherwise, it’s cash on collection, cheque, bank transfer, postal orders all welcome. All funds to clear before sending item
