ok ill bite in regards the Specna Its a 1 of 1 custom painted by geartechcustoms with plenty of photos not a retailer by any stretch of the imagination I just base my prices on what I see around Im always taking offers and as many people are aware always trading if theres any issue with something I have up do let me know happy to discuss

Landed! No ones ever seen one of theses before 😂

Just to give a little data to this thread/topic and to see for myself if there is a significant difference in the behaviour of Bios in wet conditions or a difference between the behaviour of Bios versus Non-Bios, I put a small sample of whatever I had in the house into ziploc bags of water following my last post so these are figures based on the sample BBs being completely submerged in tap water for 18 days (it was night time so I'm counting only whole days). Following the submersion, I measured five BBs from each wet sample and five BBs from the original dry source bottle/bag. I don't have a massive selection and most of those are Bio so I don't have a great control group of non-bio BBs to select from. So, the hypothesis tested is that Biodegradable BBs swell out of spec on absorption of moisture. The attached table is a summary of the results and I think the conclusion I first draw is that there is no absorption or swelling of BBs after nearly 3 weeks underwater. The variation within samples appears greater than that between wet and dry in most cases. Also, I am pretty happy with my standard choice of Nuprol RZR 0.28g Bio 😉 There are obvious limitations to the test, primarily in that the sample sizes are small, I can't be fussed expanding the test but I'd be more than happy to applaud anyone who wanted to, I am happy to email the full data table with individual measurements, if anyone is that bored on lockdown. Another possible source of error is the measurement equipment, I used my general garage micrometer to do the measuring, it doesn't have a valid certificate of calibration and it has a stated precision of 0.01mm so the variation seen in most samples falls inside the possible error of the test equipment. Thirdly, this isn't a blind test, I knew what each sample was and so there may be subconscious bias but I doubt it. I really hope this lockdown ends soon, I clearly have too much time on my hands.

TRMR anyone? Linky

I've been doing some comparisons of the bio BBs I have over the past week or so as well - ASG Open Blasters, BioSphere, Nuprol RZR Bio, all in 0.2 & 0.25g. On paper these should be identical - they're all supposed to be 5.95mm with 0.01mm tolerance either way - and while they all perform adequately enough at 0.2g in my experience from shooting them prior to the lockdown the ASG Open Blasters seemed to the best of the three, and the Nuprols had a habit of double-feeding sometimes. I haven't used the .25g BBs enough to have any idea which of those three shoots the best though. 20 of each BB were weighed and measured and they were broken apart to check for air bubbles. When measuring a BB's diameter I rotated it and re-measured to check the variation in diameter around it & get an idea of its "roundness", noting the min, max and average diameter. Some were measured then soaked some in water for >24h (was generally around 40h-ish) and then re-measured to check for any swelling due to water absorption. There are some caveats to keep in mind: The scales I used only have a 0.01g resolution which isn't really precise enough (and they're cheap, so they're not exactly top quality either) however they should at least be sufficient to show up any significant discrepancies between the specified weight and actual weight. They're also sensitive enough that things like airflow around them can skew the result. To attempt to compensate for these to some extent I weighed each BB repeatedly and used the most frequent result. Similarly, my digital calipers (Facom 1300EA) have a resolution of 0.01mm so borderline values might read either way, but again this should be enough to show any significant variation at least. Just because I didn't find any air bubbles in a BB doesn't necessarily mean that there weren't any; there could have been some in the parts of the BB that were not exposed or they may have been too small to see with the naked eye. Also, 20 BBs is a small sample size So this isn't exactly a rigorous, in-depth look & you shouldn't take the results as entirely accurate. Also they're likely to vary from batch to batch, with some being better or worse than others. But it should at least provide some interesting information & comparison between these three brands of BB beyond merely shooting with them Nuprol RZR Bio 0.20g: Weight: Typically 0.20g, 3 measured 0.21g Size range: 5.92 - 5.95mm; 11 measured within tolerance. Roundness: 13 measured with max variation of up to 0.01mm, 4 with 0.02mm, 3 with 0.03mm There was no sign of swelling after soaking in water. Nuprol's BBs have a consistent weight but their measured size was outside of specification on almost half of the BBs tested - minimum measurements of 5.93mm were not uncommon and a few were even as low as 5.92mm. None measured above 5.95mm. They are relatively soft though - I had to be very careful when measuring their size & shape as it was very easy to read lower measurements even with the small amount of force applied by the calipers. I did not see any bubbles inside any of the BBs tested. BioSphere 0.20g: Weight: Typically 0.20g, 6 measured 0.19g Size range: 5.94 - 5.96mm; all measured within tolerance. Roundness: All measured with max variation of up to 0.01mm (15 did not vary to an extent I could measure with my calipers) There was no sign of swelling after soaking in water. BioSphere's BBs are quite consistent in weight (trending more towards the lighter side) and impressively consistent in size/shape, measuring 5.94-5.96mm with no more than 0.01mm variation in diameter around any given BB - all within the specified 5.95 +/- 0.01mm tolerance. They readily split into fragments when crushed, and unfortunately I found a bubble in every BB I tested. Here's a photo of one that I managed to crack open more or less cleanly showing the air bubble: ASG Open Blaster 0.20g: Weight: All measured 0.20g Size range: 5.90 - 5.96mm; 6 measured within tolerance. Roundness: 9 measured with max variation of up to 0.01mm, 7 with 0.02mm, 3 with 0.03mm, 1 with 0.04mm There was no sign of swelling after soaking in water. The Open Blasters had a very consistent weight with all of them measuring 0.2g, but their size and shape varied to a greater extent than the Nuprols, from 5.90mm to 5.96mm. One of the BBs tested varied between 5.92 and 5.96mm! They seem to be of a similar material as the Nuprol BBs but a lot harder. I did not see any bubbles in any of the BBs tested. Nuprol RZR Bio 0.25g: Weight: All measured 0.25g Size range: 5.91 - 5.95mm; 3 measured within tolerance. Roundness: 15 measured with max variation of up to 0.01mm, 3 with 0.02mm, 2 with 0.03mm There was no sign of swelling after soaking in water. Unsurprisingly these are much like the 0.2g version - their weight is quite consistent while their size and shape is about as variable, though they seem to be a bit smaller on average and a couple measured as low as 5.91mm. The 0.25g Nuprol RZR Bio BBs are significantly harder than the 0.20g version and didn't deform so readily. I did not see any bubbles inside any of the BBs tested. BioSphere 0.25g: Weight: Typically 0.25g, 9 measured 0.24g Size range: 5.93 - 5.94mm; 16 measured within tolerance. Roundness: All measured with max variation of up to 0.01mm (17 did not vary to an extent I could measure with my calipers) There was no sign of swelling after soaking in water. These varied a bit more in weight than their 0.2g version, and like their 0.2g version trended towards the lighter side. Their size and shape was very consistent too with none varying by more than 0.01mm, although they were slightly smaller than the 0.2g version with all of them measuring between 5.93mm and 5.94mm. Unfortunately, just like the 0.2g version I found an air bubble in every one of these I inspected too. These were also much harder than the 0.2g version and they had a tendency to shatter suddenly once they started to crack but I did manage to break open cleanly for a photo: ASG Open Blaster 0.25g: Weight: Typically 0.25g, 6 measured 0.26g Size range: 5.90 - 5.95mm; 1 measured within tolerance. Roundness: 13 measured with max variation of up to 0.01mm, 4 with 0.02mm, 2 with 0.03mm, 1 with 0.05mm There was no sign of swelling after soaking in water. These seem to be slightly less consistent in weight than their 0.20g version, trending slightly towards the heavier side. Their size & shape is about as variable, ranging from 5.90 to 5.95mm and like the others these also trend slightly towards the smaller side. I did not see any bubbles inside any of the BBs tested. As I posted earlier in this thread, AFAIK most are made from PLA & as such I wouldn't expect them to biodegrade very quickly in the environment.

I appreciate a decent loadout and love realistic looking guns but I try not to take airsoft as serious as others, I have NO problem with two tones, wild colours or dressing as a unicorn to play. After all its just a game of dress up pretend soldiers.

I would genuinely do it his work is top notch if you do it in pink though im sure you would become the biggest princess on the field

I shouldn't be talking as I'm building a pink tournament M4 myself, but that thing is da big gae.

Ive got an unreasonable one in PM, think he’s too scared to show his face here 😂

Technically my box o' bits m4 is "unfielded" That is to say the gun as a whole has never been fielded but only one component in the whole gun has truly never fired a shot in anger.

Yep that's my asking price fubared lol

You can still get throwing knives

@Jedi_Master I think I need a puke emote for the "Like"/Reaction pop out bar with some of these guns that keep appearing 😂

That would be a much longer study 😂 But I do wonder myself, has the tech improved or have manufacturers found the formula that gets them as close as possible to being able to claim biodegradability while being as shape retaining as possible? I heard a podcast discussing the subject a wee while ago and I think that almost all BBs, whether Bio or not, are made in the same factory, the podcast mentioned HPA BBs as being particularly good and made in a different way but that's a nightmare of a search term so I can't find any sources for them in the UK to have a blat with. The one trend that is fairly visible on the measurements is that the measured diameter has consistently reduced (though within the error of the measuring system), this could indicate a softening of the BB shell and, if that is the case, there could be some increase in the deposits left in barrels? This is a ridiculously extended test though, if anyone had BBs they'd left in a bottle of water for three weeks and put them through a mag, I doubt barrel cleanliness is high on their concerns.

Thanks for that. It makes me wonder how biodegradable these Bio BBs really are. I suspect that manufacturers realised that true bios had swelling problems from absorbing moisture in the air etc so they changed the formula to be higher percentage plastic or whatever the composition is. So now they're probably no more degradable than normal BBs Next test would be to bury 10 or each for a year and then compare them

I've just struck a deal on this. 300 fps, with a hop, and a functioning grapeshot. Probably wont see much action at all but it's a true one off.

option D- borderlands theme....

What's funny is Skara's "spoken" (aka typed) is generally better than most of us brits lol 😏 Seeing it made me think, if, god forbid, we were all forced to use two-tones, would players: A. Hang up their guns ? B. Use two-tones, in the usual stock hi-viz colours ? C. Say feck it, & paint your guns in the most outlandish spray jobs possible, embracing all the colours available, including pink ? After all, as the late great Robin Williams once said, "its war baby, lets clash"

Nothing wrong with pink. That vector is lovely. I’d rock that in the field.

Shhhhhhhhhhhhhhhhhhhhhh Wasn't there some advert a few years ago about some man's fragrance which went along the lines of:- 'Real Men wear Pink'? ...... No, nope, Nein, Nada, Never lol It's simply a language thing ain't it? Innit? We can forgive Skara right guv?

Should mention, the 303mm is bridged where the 430mm isn't (referencing the Laylax PSS barrels). If you run an Autobot or similar you will need to remove the bridge with a file. Spring; https://www.bullseyecountrysport.co.uk/action-army-vsr-10-bar-10-m150-sniper-spring-21863-p.asp

Oh sweet Lord what is that? A my little pony pea shooter 😂

Ahh fair, nice to see someone doing their own research. Like you say there's enough people spouting that they can hit a man size target at 300 feet with an out of the box G&G raider Airsoft metres and all. My barrel is fine at the distances I engage at so personally no need to change for me! Really we should bin chronoing on 0.2s for any springer/HPA gun and chrono on the bb weights people are using (AEGs are pretty hard to overvolume from what I remember reading). But getting everyone to switch around to that will take a bloody long time. There's nothing else like it, at least for me, than creeping through the woods and getting that first shot hit and seeing others confused at where the hell it came from. This is the main thing, the amount of people I've seen around the net trying to tech and get their FPS right without a chrono is mad. It'll take a bit of time to get that hop dialed just right and get everything perfect, but man is it worth it. Looks good! Just make sure you give it a clean before you fit it to get rid of any factory/storage gunk Eagle6 are decent, like @Davegolf said they can be expensive some times so shop around. If they're the only ones with the barrel about though and you're hankering I know what I'd be doing🤣

Cheers fella, will give the file a go!

it’s the postage costs from Australia

Used with a worthless holster for £65 or brand new for £60 🤔🤔🤔

This one isnt mine, but it's just fantastic. An airsoft lemat revolver with a functioning grapeshot barrel to boot.

quaratine purchases came in. nice.

Finally got the correct green, so helmet 2 of 3 is now painted. I figured if I couldnt find a tropentarn cover, Ill just get a tan cover and paint the helmet. There may be another setup here soon... Before: After:

that cutter looks fine. i think what a lot of people do is tighten the cutter too much and crimp the pipe. if you get the new valves and don't want to have another crack at it, I'd happily do it for you, but you'd have to post them. Don't let it put you off. i was having a play with mine today and i can't put into words how awesome they are.
