Don't use this very close location / proximity to assume they're the same business. You may already know this but like minded manufacturers in China often congregate in very small areas, often unique businesses but they all use very local suppliers for parts / sub-assemblies.3 points -
Barrel length effects on accuracy - Breakdown and recommendations
ak2m4 and one other reacted to Pseudotectonic for a topic
Does barrel length affect accuracy? Yes? No? How? And how much? -- Let's do a simple thought experiment. Using maths, and a very typical situation. I have a variable barrel that goes from 50 mm to 550 mm. And I have an imaginary target at 30 metres. I want to find out the different ways the difference in barrel length can affect the grouping diameter. For the purpose of this calculation, we can eliminate the factors of air volume and hop up. Because for every build these would have been tuned accordingly to work with each barrel length. They will all have been tuned to output the same joule with the same BB and with the same hop up performance. Therefore this calculation deals only with the geometrical effects of a longer or shorter barrel. -- Diagram A: Spread introduced by barrel BB travel Assume the barrel is a stock 6.05 mm barrel. The BB has a typical 5.95 mm diameter. Therefore the variation is 0.1 mm. Assuming the BB travels in more or less a straight line, this 0.1 mm variation at the barrel exit will give us the worst case BB trajectory. The final spread diameter at 30 metres is therefore a simple triangle calculation. -- Diagram B: Spread introduced by inner barrel wobble inside outer barrel Due to the construction of airsoft, the inner barrel is normally not fixed inside the outer barrel, but simply rests inside with a little clearance space around. During the firing cycle the gun will definitely be subject to vibrations of all sorts, making the inner barrel essentially wobble inside the space it occupies. Assuming this clearance is 0.4 mm (measured from an AEG) we can similarly calculate the spread it creates at 30 metres. -- Diagram C: Spread introduced by difference in ergonomics A longer barrel will allow you to hold it steady at two further apart locations, because of the longer handguard. This can be fully exploited to create a more stable barrel. Assuming your most steady hand will involuntarily sway within a 2 mm range, we can again extrapolate its effects on the grouping using the same calculation. -- Factor D: Wind There is no diagram for this because wind is not affected by barrel length. We assume a moderate wind affecting our BB at 30 metres to introduce a spread of 50 mm. -- Results: In the order of significance, the barrel length can influence the accuracy through: - Ergonomics - Inner barrel wobble - BB travel inside barrel I will discuss each below. The biggest advantage of a longer barrel has surprisingly nothing to do with the actual ballistics of the BB, but the effect of simply having a longer stick to hold onto gives you a better control of the aim. For shorter barrels below 200 mm, the ergonomic disadvantages will affect your accuracy a lot for long range engagements, although the shorter builds are better for CQB where accuracy is less important than manoeuvrability. The biggest thing you can do to exploit the advantages of a longer barrel in terms of accuracy will be to eliminate hand sway as much as possible while making use of the longer form factor. That means using bipods or resting your gun at something solid as much as possible, and so on. Again it remains true that it is 99% the user and 1% the gun. Even with worst case geometrics, the inner barrel wobble and BB travel inside barrel does not really introduce much spread once you go above 200 mm barrel length, where it generally becomes less of a problem than actual wind blowing your BB. Above say 300 mm, the effect will become so small it becomes virtually no difference in most practical situations. -- Recommendations: - Below 200 mm is strictly for CQB. The BB, the barrel, and the gun itself will all suffer from stability issues for making accurate shots. - While barrel length affects accuracy in pure mathematics, the ballistic effects will have become virtually irrelevant above 300 mm. - Longer barrels (longer guns / sniper rifles) can potentially have better groupings, with the right skills, and probably with the right bipod. - The best method to improve accuracy is improving largely your skills, not your gun. Conclusions: Nothing is new here, but I guess you can't really snipe with an MP5K. But you can potentially snipe with an MP5.2 points -

How come this never used to be a problem? Surely women have huge experience carrying plates? In fact they should be regarded as experts in the field with centuries of going back and forth to the kitchen. Often also carrying food as well! Awsome. Sometimes the lack of respect for women infuriates me. 😡 Then I talk to my wife.2 points -
Barrel length effects on accuracy - Breakdown and recommendations
Rogerborg and one other reacted to Adolf Hamster for a topic
It's an interesting dive, but there are some thoughts to consider. First is straightness, keeping a half metre tube straight to within the diameter tolerances we have is unlikely when things are being produced as cheaply as possible. Not to mention that the inner barrel might be perfectly straight but the outer has other ideas. I have pondered that a barrel curved intentionally downwards to force the bb to ride on its top edge (thus adding rather than detracting from the hop spin) could theoretically give better stability. I have a vague foggy recollection the americans had some sort of miracle barrel with a groove in it to acheive this but that's got as much weight behind it as the tk twist. Second is the concept of stabilisation ie the whole riding on a cushion rather than bouncing off the walls, which i've yet to see the kind of full nerd level fea type analysis to confirm if it's even a thing, let alone give an idea of where the sweet spot is in terms of bore/length and the effects of bb weight and energy level. I suspect if it is you'll find that for a given ammo/energy level, too short gives too little time for the transition from bouncing to drifting, and too long reduces the pressure to where it can't even initialise stability in the first place. And third is the everything else that goes on in our systems, which is why my typical summation is that barrel length is mostly irrelevant as simply getting the rest of the pew good enough to even notice the change is a challenge in an of itself. Which ultimately boils down to barrel length being a choice made on other factors, like the handling, aesthetics, and wether your chosen field/style of play grants a benefit or a penalty to running a longer gun (ie poking through hedges outdoors or handling in tight spaces indoors)2 points -

Here is a lovely looking 'Springfield Armoury' Replica using the Tokyo Marui V10 1911 Ultra Compact, which has the frame and slide swapped out with a two tone Guarder Aluminium kit, and Kimpoi 'Springfield' real wood hand carved grips. Comes with a beautiful real steel leather 1911 holster from Galco and 2 TM gas tight magazines. Cycles cleanly, lovely shooter. Its worth noting that this isn't stainless steel, so its not as heavy as it looks but better than the oe TM plastic, and feels great with the mag in. Price includes shipping, but not any PP fees.£310

you read right 🙂 260 to 300 seemed the sweet spot. Of course this is my own testing, the longer ones still performed well but just not as good as the shorter ones.1 point

Yes it's highly possible. I also found that having the last 3 or 4 inches polished to a high degree can make big improvement for any lengths.1 point

Maybe consider a warrior tmv vest or one of the many similar "vests" , it's essentially a molle waistcoat & gives good coverage all over, allows for pouch placement wherever you want & once adjusted goes on like a jacket, very comfortable & should take the sting out of most shots. Obviously to give the best advice to sizing & coverage etc, we will need to see suitable pictures of your gf 😏1 point -

What's reasonable in the Ghillie/Leaf suit world?
The Waco Kid reacted to Impulse for a topic
A shoulder piece or cape is all you need and I think the all-over suits that most people wear are a waste of time and just get snagged on everything. I'm pretty much a full-time bush and I never use ghillie trousers or an all over leaf suit top; as long as you keep still and don't silhouette, you'll be surprised just how much you can get away with. I'd have a look around Aliexpress, honestly. I just typed "ghillie" into the search bar and it came up with a bunch of stuff that I'd try if I didn't already have stuff (and if I wasn't a tall and large gentleman; Aliexpress stuff can be a bit small for me). I'm sure it doesn't need to be said, but avoid those swamp monster suits.1 point -

The Waco Kid reacted to Fatboy40 for a topic
You'd be very surprised what's available on Ali Express and how good some of it is, and how easy it is to improve it. When I get home I'll add some links for the benefit of you and others. (For example I use a ghillie shoulder piece, that's almost identical to the Novritsch one, but which is half the price. Also there's mesh available that's almost as good as the Mustang mesh but a third of the price).1 point -
M16A1 low fps - theory?
pyromancer6 reacted to JinxDuh for a topic
Update: Fitted the kit supplied by AK2M4, sadly the longer nozzle was out of stock so used a short green one. Up to 312 fps on .2g as the spring suggests it should be. Turned out Specna just had some bad air seal I guess 😂1 point -
They were (based on the face level of reporting*) acting in a manner that members of this forum and responsible airsofters would not endorse. They were a bit naughty, brought attention to themselves and got caught. * the area does have some ‘green’, I’ll be more sympathetic if in their minds they went somewhere out of the way, had a few test/practice shots in a bush and ended up in trouble As opposed to heading up the street and shooting a bush With their ages their should have been some form of common sense, but it’s not as common as we may wish1 point

You're right that there's many self proclaimed official airsoft groups, but the sum total of what they've contributed to the hobby is ⅘s of fuck all. If I had a pound for every time a new organisation popped up claiming to be the saviours of airsoft, only to never be heard from again I could probably afford a TM NGRS upgraded by DCA. As for other shooting groups, they'll often try to distance themselves from airsoft and in the past have seemed to deliberately throw us under the bus in an attempt to save themselves. To me this is very short sighted as many airsofters are interested in other shooting disciplines.1 point

My personal view is that it doesn’t matter what clowns/party are in charge. They would all ban anything in order to get votes so political affiliation doesn’t matter. All these people want is to line their pockets at the expense of us. Apologies but I’m so disenfranchised with politics in this country. I can’t see it being better under labour or greens or anyone else for that matter.1 point
