Oops... I meant the right side. I meant the right side.

yes sorry, that's what I meant. also could have been someone used some non-silicone grease and it's degraded the rubber on the pad, even with no load on the spring will create a nice pretty pattern on the pad 🙂

My thoughts and musings. Red is Butyl, grey is hard foam or washer, green is sound. I haven't drawn in the barrel, but there should be a taper ( in butyl maybe) from it to the butyl in the first stage. Send sound through a hole and it propagates outwards in an arc originating at the hole so long as the hole is small enough ( which it is in this case). The sound level reduces with each hole it passes through if steps are taken to absorb the sound after each hole. An empty silencer can rings because of resonance, alter the resonance and can will absorb the sound instead. Absorbent material like butyl is soft and dense, most metals are too hard to use, it will alter the resonance and absorb sound. Foams will only absorb sound. Rubber washers make good separators as does the rubberised foam in HVAC stuff. The volume of air being moved is the volume of the cylinder, you need to reduce the speed of this to reduce the noise and/or absorb that noise. The diameter of the silencer will do this not the volume as the air will slow to fill a wider space but should be gradual to prevent a sudden release of pressure. That amount of air will still be pushed out the end of the silencer so it is always important to not be over volumed or the exit hole of the silencer will behave just like the barrel end but with a larger, quieter exit. The holes in the end of the silencer system will get larger further from the barrel.

Hi hoping someone can help me I'm having a slight issue with my bolt m in my vsr one every 10 or so shots the air line pops down slightly and I lose power so I have to push it back up and it's fine again the issue is in the normal vsr it rests on the trigger guard where the vsr one doesn't have that on the trigger box as it's built into the stock so there's abit of a void. I've attached a pic of the part that drops down. Has anyone had this experiance with the vsr one hpa or a solution.

Neither. I made it for the event. It's a Fast helmet from eBay with polypropylene stuck around the edge and finished with car trim. The code discs are from eBay as well. It's based on the Imperial helmets from the Andor series.

Welcome to the madhouse A crack habit is probably cheaper😁

Is that an Iraqi Fedayeen helmet or do you also cosplay as Dark Helmet?

Don't mean to sound funny here but if you're shooting right handed then left side sling loop is the default, assuming you're looking from the butt end of the rifle down the bore, lol (i.e. same side as the mag catch). If you google image 'L85 airsoft' though there are indeed plenty of them on the right side of the weapon i.e. same as the ejection opening, which would of course not work out. ETA - looking through a small portion of the search results, seems that the ICS and G&Gs get it correct to the real rifle, but a lot of stock/retail pictures of the WE, Army and generic springers have it 'wrong'. Which as someone who's always been anti-WE gives me a weird little buzz in a bad way 'cause I'm just a bad person like that.

Eh? The sling loop is on the left for righty shooters to sling it crossbody.

Just theorycrafting here... just a sketch to note down what we have to deal with... 1. Vibration damping: We know the case will resonate and vibrate from any sound from inside (air expansion) and from the barrel (piston impulse) so the case need to be treated to become a composite material so any vibration is deadened rather than resonate, can be achieved with a lining of vibration damping tape or with similar principle 2. Air gap: To limit energy transfer from inside to the case, maybe we can leave an air gap so all the air expansion is contained and processed inside, rather than transferred outside to the case 3. Absorbent material: We need to convert as much sound into kinetic energy as possible at this layer, maybe a heavy and absorbent material, maybe some sort of rubber or silicone or something along those lines 4. Air expansion chamber to match the cylinder volume ~1:1 so the space can be filled with as much absorbent material as possible (for the highest conversion ratio possible), geometry to match the air expansion pattern, and/or optimised for absorption (depending on how the absorbent layer is made). This area probably needs to be towards the back. 5. The "exit tunnel" of the BB should be towards the front so any leftover sound from the air expansion zone can be limited, we just want the BB going out but with minimal air pressure i.e. sound. TLDR we need to convert the vibrations into heat as much as possible, and we try to do this inside while limiting any transfer to the outside

Yup. I'll be there to be shot at by the sneaky VC all day. The Firebase has had a lot of work done to it since the last 'Nam game, so I'm looking forward to testing out the upgraded fortifications. @Skullchewer - I'm really glad you enjoyed the game on Saturday. I was there as well on the blue team and had a cracking game. Top marks to the lads on the green team that held the mortar pits all morning. They made our lives so difficult, it was ridiculous - even more so as there were only a few of them hanging on to the timer. We seemed to get our act together by the afternoon and managed to turn it around, but regardless of the result everyone seemed to have lots of fun, which is what makes these events memorable. It's worth saying as well that if you like the filmsim genre Gunman hosts all sorts of games at filmsim.co.uk, including Nam and Cold War, although I have to say the highlight for me this year was the "Outer Rim" game a few weeks ago on May 4th (it's really Star Wars but don't tell Disney 🤫). The effort everyone made by everyone was extraordinary. Courtesy of Chris Thomas Photography these are a couple of pictures from the event, including a Tusken Raider, a hirable Battle Droid and finally me as an Imperial Trooper. I can't quite bring myself to post pictures of the New Republic Forces as it's all rebel propaganda 😄:
