Nope. It's designed for the significantly heavier BCG used in the T8/CGS system, it'll put extra unnecessary tension into the FCG and will undoubtedly cause the bolt catch to stop working.

Vapor pressure of propane at room temperature of 25 degrees C is 8.3bar / 122PSI Probably need to be removing them then, if you can make them work without the NPAS great, but I doubt it. If you need a UK supplier of a better NPAS, Jaeger Precision makes them as well https://jaegerprecision.co.uk/products/jaeger-precision-mws-npas-adjustable-valve

Acetech Blaster M module is what they come with.

How old are your FEDA's? This sounds like the old 3D printed resin ones which really, really don't like staying consistent as the adjustment screw has a tendency to walk from them as threadlock can't bind to the resin.

It's not part of the Mainland as far as RM is concerned. PF applies a 70-150% Surcharge on parcels shipped from Mainland to NI - i've shipped maybe 50 parcels to NI in the past 3 years, you may not think it is the case, it definitively is the case and has been the case for over a decade. Just like shipping to the Highland or Islands of Scotland is more expensive. They are not within scope for normal Mainland deliveries. https://www.parcelforce.com/sites/default/files/parcelforce-worldwide-account-surcharges-and-additional-services-guide.pdf DPD for example, won't even ship to areas of the highlands at all.

It can if they're in Northern Ireland. Why when i'm including P&P on sales, I specify "Mainland UK, not NI".

Tracer version, I had to cough up nearly £150 for, only for said tracer to die 6 months later.

Even at used value the PTS version of the Dead Air thing is around £70-80, so not surprised he's making that extra based on the other inflation.

UPL has molybdenum disulfide in it which is worse for rubber than silicone oil.

After a hiatus on airsoft spending for a few months - Miltec Trousers and UBACS in Phantomleaf WASP I Z3A 5.11 Double Duty (RG/BK) Belt Airtac MWS Modular Adapter with M4 Base Airtac x T1P Dead Drop Grip and Trigger Guard x2 RATech WA to WE barrel adapter 5KU WA 9" Outer Barrel Guns Modify 3.5 MWS Nozzle x2 Jaeger Precision MWS NPAS (updated version) as a spare Jaeger Precision TPU buffer for Salvo Precision MCX (if I ever buy one, it'll be handy to have it already) Not having to spend money, because of RMA on warranty, Airtac also replaced my Gen 1 WE M4 Adapter with not only the modular Gen 2, but also the Gen 3 for the V3 WE system. Traded a pile of WE M4 PMags for a TM M&P9 with Nova Slide kit and other gubbins + 3 mags also.

Norsso is a firearms manufacturer, they do not make airsoft pieces. So slide etc are clones. Sig uses black machine screws exclusively on their optics, and the button surround is made with a different material to the rest of the body on Romeo-X Compact, whereas its not on this. Zenitco uses a knurled alumnium attachment screw, the design shown there is exclusively SOTAC clones. etc etc

Some creative pricing right there, also conveniently failing to mention which companies have oem'ed the clones, but even if we assume most expensive, I do not understand how that tracks to reality.

Are you still using stock hop rubber and inner barrel?

http://greendevilbb.com/ used to use these about a decade ago, and in forest sites they were near on invisible.
