@RogerborgManaged to get it sorted by using cylinder head oring that was just perfect size, only issue i had was trying to tap the pins back in but got it after few tries.

Deadly Customs for sure, I use their holster for my 1911/fnx-45 and love how it works for any pistol i put inside of it.

Not gone lie but he sounds like some 18 year old wanna be airsoft youtuber type.

@Rogerborgthey love to overdo things as always. For example the main board that trigger micro switch, and hop unit bb detect feature connects to is attached by 1 screw to the gearbox shell, that 1 screw is all that gives any kind of rigidity to the board and honestly its a bad design as i barely bent mine and it broke off. They must of had few or tens of mp7's pass qc test so they continued on manufacturing but somewhere along the line something went wrong. At least they hop design actually lifts bb's up to max of  45+ metres from what i tested with such a short barrel. But I might replace it in a future together with bucking and nub. But from all the work I've done to the mp7 it's now reliable and can easily use 11.1v lipo with programmable mosfet which comes in handy, since I mainly use semi and 2rd burst on my aeg's.

@Rogerborgany wiring that was left in the gun was basically removed. Those VFC mosfets are known to burn out like this one did so i removed all of the wiring and replaced broken trigger micro switch with new one and soldered in Perun ab++ which works much better. Also that hop unit wiring and the small spring inside hop unit together with that small chip were removed. I pretty much fixed all known feeding, fps or reliabity issues with the aeg and it works much better then i expected.

@Lozartalready seen that and its longer then sa58 barrel is, so it wont work. I contacted that shop in the past asking for details and found out its much longer then i could fit

Last I checked, both TaiwanGun and GunFire are both refusing to send to the UK, although they don't tell you this until you reach the delivery stage of the order.
 
And yes, I know GunFire still says that they'll ship to the UK if it's over £140, but when I pushed on with the order, it then said "lol jk, no we won't".
 
Others may have had better experiences.

Something to be absolutely clear on: until the goods are in your hands, they are the property and the responsibility of the seller. That's not your rail that's been seized, it's theirs.  It's been seized because of their decision to mis-declare it. It's their responsibility, not yours, to get it into your hands.
 
So I'd get on to them and tell them you'll be needing them to do that, or to refund you in full and immediately.
 
When they inevitably refuse and lie to you about it being your problem, or simply ignore you, then initiate a chargeback via your payment processor.  No need to get into the details with them, just "ordered, not received, seller is refusing to resolve, money back please".  Consumer forums have information on how to do a chargeback, including on debit cards, not just credit cards.
 
Do this in parallel.  It's better for you to have the rail and your money, than neither.
 
This is not your fault, it's theirs.

I basically have an LMG inside my ICS CXP ape, i have gate titan mosfet with 13:1 gears and piston short stroked. With m90 spring i get around 310 fps which is ideal for me and i get around 45 rps(rounds per second) on full auto. If you want your gun to shoot quicker you need different gearset, steel tooth piston, and mosfet ofc.
