Have you got your new inner barrel?  If so test it first, chrono and bb flight.  Just in case it affects the fps too much.

Yup. Just finished raging and looking at other solutions 

Urgh, tell me about it, by the time I pulled the trigger on buying an XR-5, I could only find it in DayGlo Blue, and the paint and varnish keeps wearing through on the rub points. I'll likely just start taping over it.
 
Thomas, the legal position is that it's a strict liability offence to modify a non-realistic imitation firearm into a realistic imitation firearm, even temporarily, in private: https://www.legislation.gov.uk/ukpga/2006/38/section/36
 
However, it's a defence to do so for the purposes of playing airsoft at a site with 3rd party liability insurance: https://www.legislation.gov.uk/ukpga/2006/38/section/37 as amended by https://www.gov.uk/government/publications/the-violent-crime-reduction-act-2006-commencement-no-3-order-2007-firearms-measures
 
There's no age limit on the defence, or particular criteria to claim it. The UKARA-style 3-games-over-8-weeks scheme providing the level of evidence that retailers considered necessary. You can make your own decision on it.
 
Practically speaking, it's only going to come to the attention of the state if you do something silly with the gun out in public. At that point, Firearms Act 1968 Section 19 applies, and it doesn't matter if it's a realistic imitation or not. Since you already have the gun, and haven't gone on a rampage with it, I think you can be trusted not to do so if it happens to get blacked out.
 
However, I'd agree that the lowest risk option, particularly while you're under 18, is to use sniper tape, which comes in solid colours or camos. If you tape up on site then remove it at the end of the day, then you're satisfying the letter and the spirit of the law.

That would be fine as the tape is temporary, I'd recommend the self adhesive stuff as it won't leave a sticky residue when removed. Something like this

Personally I wouldn't paint the parts as the blue will start to show though when the painted parts get dinged and scratched through normal use

Welcome to the forum
 
Nobody has a ukara licence, they don't exist. Now I've got that out of the way on to your question.
 
By cover the blue do you mean temporarily while playing or permanently? The former is absolutely fine and can easily be done with a roll of sniper tape. If you mean permanently then IIRC it's technically illegal but if you can show you're using it for playing airsoft (at a proper site, not dicking about in a mate's garden) and don't do anything stupid with it you'll be fine

Because they're stupid?
 
Don't assume that anyone that worked on your gun before you knew what they were doing!

I hear a few of those cases are still being argued out.

Thanks Colin, the phrase 'twelve men good and true,' from Twelve Angry Men went through my head as I was typing.  Genuine Freudian slip!  
 
 

Your delta is lose , front sight off with the gas tube and tighten it up making sure the gas tube can go back in , you might need barrel shims but most times they arnt needed.

Edit- how liverpool ish are you ? I'm south wirral ( ellesmere port )

I went down the wide bore rabbit hole with an SVD I had many years ago; the drop in power was significant compared to a tight bore barrel.

M160 are arriving in a few months however what's going on with that build?  Never worked on a Masada personally but why so low power ?

For the love of GOD don't start chasing FPS limits.
 
Use it, see if it's actually lacking in range/accuracy first.
 
 
As for your other question, yes absolutely if the window on your barrel is too small or if the rubber hasn't gone on properly then an MR hop will catch on the edges.
 
SHS springs can be quite wide tolerance. Pick a spring brand you like and trust (*coughs* XT @ak2m4 *cough*) and stick with it.

Fitted the omega nub with the maple leaf bucking, 298 - 307 (.25g bb’s, adjusting hop incremental and only a tiny drop) 
 
Seems I’m now on the right path, so fingers crossed all is good next month 🙏

The Begadi hop is excellent.

I'll be that guy again, and ask: if you feel strongly that UKAPU isn't doing what you want, what's stopping you from volunteering to join it, and changing that? 

It appears to me that UKARA has a monopoly of lobbying power because they hold the secret sauce data of the airsoft market. However because they are not really an airsoft association they do not have the capacity to take on the role of one. A full fledged airsoft association should really be doing a number of stuff even during "peace time", e.g. PR and promoting safety and improving the hobby etc (see suggestions from GPT above). So that the public perception of our hobby does not depend entirely on external factors such as whichever party is in charge.

In other words, the toy gun illuminati might be too good at being secretive it is unintentionally trapping the hobby in the fringe zone it originated from.

Amazingly the story of UKARA is truly becoming lost history because their operation is so obscure.
 
Here is a brief mention of it being an Excel file sitting at a site called Ironfoot Airsoft that used to exist (near the GCHQ site), but the farmhouse is now demolished.
 
So there is really no solid up-to-date information of exactly who and where and how UKARA is maintained.

Coincidentally I was trying to sort out a gun this morning that was shooting off to one side with a ZCI rotary and an Mr hop. After discounting the barrel being rotated to the side in the hop unit, swapping out the nub etc with no change, I realised something quite interesting. The hop arm on the ZCI unit had been poorly moulded. It appears moulded in two halves - and on my version, the two halves were not perfectly aligned. This resulted in a small step halfway across the 'cup' where the nub sits under the arm, therefore placing quite significant uneven pressure to the nub. 10 seconds of careful scraping with a blade sorted it, and now the gun is shooting dead straight. I've used ZCI units in most of my guns with good results, so this was a first for me. Had me scratching my head for a while!

I think for ak there's a vfc plastic rotary that's really good if you can find one, only about £15.  Maybe some AK owners can confirm this

I was looking at another forum recently and they noted an intention within the Labour manifesto to increase firearms licensing to cover the full costs involved. Now I know that's not airsoft but shooters of ALL disciplines should be aware that if one group is targeted successfully then you can bet your last BB that they will look elsewhere to do something similar.
Get more money in from our sport, maybe ban it, or more difficult to access. Who knows.
You can never trust these politicians........ 

@Pseudotectonic thanks, I'll mention the ms delay thing to the factory and see what they say. 

From what you're saying you have a MR, that's the recommended bucking and the one I use to test.
 
However your hop chamber might prefer the Macaron version which uses a slightly smaller contact patch, it's all about trying different things.  it's worth just trimming the feet of the red nub a little or try the MR bucking with the stock nub. 
 
With the inner barrel and hop chamber outside of the gun apply the hop and look down into the barrel and see what the contact patch is doing, should give you an idea
 
 
 

Rubbers will break-in over time, you generally end up applying a little more hop to compensate.  Not every hop chamber is the same so it takes a little playing around with.  It sounds to me like the nub is perhaps a little too large (tall) for your hop chamber, although impossible for me to tell without it in front of me.
 
You might try trimming a little of material off the top of the nub to reduce some of it's height.  Also as a test try a standard nub if you have one there.
