Honestly, though I cant speak for anyone else, I would never touch a 2nd hand battery, especially if they have started becoming puffy. Chuck the puffy ones and try and sell the two that arent. 
 
 

The quality control on AK rear and front sight alignment is just awful. I have bought at least 6 AKs from LCT in past and I had to return 2 of them because the trunnion pin holes themselves were so  badly drilled that the rear sight could never be aligned correctly with the path of the BB.
 
Even when the trunnion is drilled in the right place, the front sight still needs a hammer to adjust it in the right place because the front sight pin holes are not drilled/pressed in the right place.
 
Are there any plans to make this process more accurate? I have never had this problem with E&L AKs.
 
 
 
I would love to see the AKM-63 back in the UK 

I would no get one if only for the old school TM style Hop unit adjustment. It's incredibly easy for it to adjust itself after full autoing. The only MP5 style I will get is one with the sliding style hop unit.

Just wanted to share my experience flying from Spain (Malaga) to the UK with internal airsoft parts in my carry-on luggage, in case it helps anyone considering the same. This could probably help in some other EU countries as well. 
 
Background:

I only considered doing this because I had pre-purchased parts from Finland and Italy to arrive at my address in Spain.
Nearly everything was RetroArms parts at significant discounts — hard to come by and expensive to replace. The only non-RetroArms item was the LCT AK magwell spacers.
I was trying to avoid shipping them separately or risking them in checked baggage due to time and coordination issues.
 
Previous Experience:

On a past trip, I had tried to take an airsoft pistol magazine in carry-on. In hindsight I couldn't believe I even tried this, I should have known better. It was flagged immediately and security said I’d have to either check it in the hold (too late) or have it confiscated. I chose the latter.

Lesson learned: magazines are a definite no in hand luggage.
 
This Time:

I packed the following internal-only parts in my carry-on:
2 gearboxes
2 motor cages
2 spring guides
1 cylinder
1 cylinder head
LCT AK magwell spacers
 
Nothing was externally gun-shaped or capable of functioning on its own. All were purely internal upgrade components.
 
I also brought:
 
Paperwork detailing what the items were, receipts and why I had them. In both Spanish and English.
My best attempt at staying calm and cooperative despite being rushed (I woke up an hour before the flight and was rushing like hell to get to the airport, don't do that!)
 
What Happened:
After going through the scanner, my bag was immediately pulled aside. Security flagged the contents as “weapon-like in nature.” I explained and handed over the documentation. A police officer was called. Thankfully, he knew what airsoft was and confirmed the parts were internal-only and not part of a replica. He still went to check with his superior, since it was a fairly large quantity. The superior gave the green light, but warned me not to do it again, emphasizing that other officers could have refused it entirely.  
I ended up having to sprint through the airport and barely made my flight. It was a close call as I had 7 minutes to run from Security, through Passport control and to the gate at the furthest end of B Terminal!
 
Key Point:

Even if what you’re carrying is legal, that does not mean you have the right to bring it in carry-on.

Airport security and airline staff have full discretion to confiscate or deny boarding over any item they find suspicious, even if it’s not prohibited by law.
 
Final Thoughts:

I got through this time because I had paperwork, remained polite, and the police officer was informed.
But it could have easily gone the other way.
 
TL;DR:

Only tried this because I had pre-bought RetroArms parts at a discount, shipped to Spain from Finland and Italy.
Packed all internal parts: no replica externals, no magazines.
Bag was pulled aside, police were called, and I was let through after a warning.
Legal doesn’t mean allowed — security can refuse anything.
Wouldn’t try it again — too stressful and risky.
If you do intend to try this. Please make sure you heed the above!

TL;DR:

Only tried this because I had pre-bought RetroArms parts at a discount, shipped to Spain from Finland and Italy.
Packed all internal parts: no replica externals, no magazines.
Bag was pulled aside, police were called, and I was let through after a warning.
Legal doesn’t mean allowed — security can refuse anything.
Wouldn’t try it again — too stressful and risky.
If you do intend to try this. Please make sure you heed the above!

Dual power spring is an Low Power AEG as in. Plastic gearbox and FPS lower than 200. You need a proper AEG with metal gearbox to go skirmishing. Also the LPAEG will struggle with compatible parts. 

So in my example of an ICS SIg 551 MRS where I bought it as New Old Stock and in basic testing I found it to be firing hot, the hop rubber had perished and I had to Model and 3D print in steel a proprietary part. Would this still not be considered "As New"? 
 
When selling stuff, you only get a "As New" and "Used" Option.  "As new" by dictionary default is not Brand New, but it's closer to "Like New". 
 
So no warranty can be implied by "As New".

But a new one opening at "Somepoint" In Yalding this year. I take that with a pinch of salt, but Invictas Woodland site was pretty good, so it's a shame to hear.

So the gearbox in my E&L AKM is deemed to be defective as the Motor cage wont attach tightly enough in any direction and sounds awful as soon as the pistol grip is attached. 
 
Decided to swap in the gearbox in my LCT AMD-65 to the E&L (Whilst swapping the Cylinder to a full type. And going RetroArms/Mosfet for the AMD)
 
RetroArms V3 CNC QSC Gearbox. 
LCT Magwell Spacer x2
RetroArms CNC Cylinder Head
RetroArms CNC Type C Cylinder
RetroArms CNC Steel Bearings
RetroArms CNC Tappet Plate
RetroArms CNC Fire Selector Screw
RetroArms CNC Motor Cage
RetroArms CNC Nozzle (19.7 and 19.8mm)
Perun V3 Optical
Perun Clicker
XT M105 Spring
Solink 12:1 Helical gears
SHS Anti Reversal Latch
 
This is paired with an existing T238 Brushless Motor and Prommy 363mm barrel. 

Just heard that it's closed permanently. Landlord didn't want to extend the lease and all social media relating to Dogtag has disappeared. 

I have sold to the Channel Islands before and it means that the Importer has to make sure they follow all the local laws required, but also the exporter has to fill in a declaration form. Honestly I would rather avoid going through it again,
