Air Arms S500 vs S510

Yeah! I sure am excited to get my hands on an AA PCP. I was thinking about a regulator but wasn’t sure if what exactly I needed to do. I also hear that if you put a regulator on it you can actually fill the cylinder much higher than AA actually states, like up to 300 bar, because the hammer and something else are designed for pressures like 200 bar? Not sure but it’s what Matt Dubber said on a video of his. Anyone know if that’s actually true? (Not that I would even think about doing this to such a beautiful air rifle)

Don't fill it higher than the pressure than the pressure that is indicated on the cylinder cylinder.

If you fill it tot 300 bar, there is a change that you need a new cilinder, it will flare the ende and blow off.

Most regulator manufacturers also say that you need to use the factory pressure .

For AA that is 250bar for factory regulated models and 200bar for non regulated and aftermarket.

What’s different from the 800 regulated S500 and the 700$ unregulated one? Why can the regulated one be filled to 3600psi and the other one only to 2900? Are there parts differences other than the other one has a regulator?

EXCELLENT QUESTION. Yo!

Good question...a regulator alone can never change the rating of what pressure an air cylinder can hold...unless its in a different cylinder with burst discs to prevent the original cylinder from never seeing such pressure...



The valve retention screws, and fill adapter, both will see the increased pressure unless the regulator doesn't butt up against the valve, in which case, how is the regulator retained? I know in the 510's its a butt against the valve type, so therefore unless there are increased safety factors via larger tube, more retention screws, or better material, this change in 'max fill pressure' from regulated to unregulated is nonsense...if both use same material/retention methods, then their fill pressures are the same, be it 200 bar or 250 bar, neither of which have been confirmed because no ones running those tests or running the math. I don't know how their valves are retained or their tubes material / thickness...
 
They are available in .177.

Can you post a link? I cant find any in 177 for 700-800 price range

Don't think you will find any at that price, but Pyramyd has them.

You are right PA has them but only in .22. And no option for different calibers. 

If they were in 177 i would take

I just looked, and PA has both the S500 and S510 in .177, in stock.

but it costs 1100 because of walnut. not everyone wants to pay that much and just wants poplar stock and 177 caliber for 300$ less

A original regulated s500 had a completely different setup than a aftermarket setup. 

Over the years i have seen several Air cilinders that did fail from a to high presure. Better safe than sorry.

Ik would get the original regulated model.

Well, maybe someone with some serious airgun experience with some of the S500s should start doing some tests.

Im pretty sure max fill pressure on aluminum bottles is 3000psi where alloy is in the 36-3700psi range and carbon fiber is 4500psi. I looked at Pyramyd air and the unregulated one has a slightly smaller cylinder than the regulated one. I’m sure there’s something different between the two, but they both have the same material cylinder.



i think I’ll enjoy my new AA but the shot count I’m sure is like 20 shots per fill, which kinda sucks. I might buy a regulator for it to get more shots out of it but I’m sure that a 3600psi cylinder certainly helps with getting more shots.

Would if be okay to fill to 3000psi instead of 2900? 
 
The only reason I can think of being unregulated's fill pressure is 2900 is the hammer spring / weight combo work best in the range of 2900-2000 (quite common that unregulated pcp's are built around a fill pressure range)...



I could be wrong and there are differences between the material / retention methods...If anyone can confirm this then it would confirm the above reasoning...

Yeah, that’s what Matt Dubber said in his vid about regulated and unregulated PCPs. I looked at Huma regulators and was thinking about getting one in a while. What would I need to do to set one up?
 
If it were me id just leave it be dont mess with a good thing and just fill to 2750 to 2800psi shoot 30 shots then refill how difficult could that be? Your Huma or whatever brand regulator is one more thing to worry about going bad with the recurring potential to throw your first shot astray whenever it sits for some hours. Yo!

Really? I’ve gotten to shoot a BSA Superten thats regulated and it’s like 10 something years old. I’m sure regulator tech has advanced somehow in the past 10 years making them more reliable right?
 
Honestly my most long term dependable PCPs are unregulated guns that were never fooled around or tinkered with that I can just grab any one of them Any day any time and never ever worry about the first shot ever skewing off its intended target no matter how long they've been sitting. Most I've done were to do a little trigger work and added better LDCs. If you absolutely must tinker I strongly urge you to buy an FX Impact instead. Yo!
 
Why don't you go buy a BSA Super Ten then. Unfortunately I had the chance to buy the BSA Super Ten back in the day but instead chose to go the unregulated route and buy Theoben Rapids instead so what would I know? All I can say is those 20+ year old Rapids haven't needed any service and still keep up with my regulated RAWs that's for sure. Yo!
 
OK even though I already have 3 BSA R10s I'm going to buy the next BSA Super Ten that I find worthwhile so I can get to see what got you all hyped up about and get a first hand experience on how reliable they really are. Thanks for the suggestion! Last one I saw for sale was sold for $500 maybe even less after a very long time being relisted over and over again so it should be cheap. Yo!

If you tune a regulated rifle correctly you won't have to worry about first shot being astray any more than the shot difference between an unregulated peak/mid/low operating pressures bell curve...



Further regulated rifles are just as reliable as unregulated being that they rely on o-rings just as any air gun does and would need to rebuilt and nearly the same rate as a typical unregulated pcp...



There are far more benefits to regulated than unregulated, hence why nearly all top end pcp's have them...its not worth debating the benefits or drawbacks except for personal reasons and belief...neither of which I am willing to entertain as its not in my interest to sway your opinion.
 
DANG GOOD DEAL $450.00 22 AA S410 WITH 3 MAGS ALREADY SOLD EARLIER. MISSED IT BY JUST THIS MUCH

... Yo!

Yo, you already have more guns than this guy-so leave a few for us 'economically challenged' folks, LOL!

PS-I grabbed that one.

I had a Huma put in an old SL400, and I really think it was worth the expense. I generally shoot about 40 rounds and then refill.

I wish it would show the cylinder pressure, it only shows the regulated pressure. I also had a leak in mine since day one, but I just fill before my session and it is OK. 

I have a second unregulated SL500 in 22, and it holds air forever. I thought about having a Huma installed, but I may sell it and just get a new regulated model from Pyramyd.

I totally get it. I have a pair of Daystate Renegades and they both have aftermarket Humas as well as lots of FXs swapped out with Humas as well and the BSA Bucanneer and Marauders and P-Rods Hatsan BSA R10 Atemis M16 Brocock Compatto just to name a handful of many. I'm getting to the point to not tinker with the gun unless absolutely necessary that's all. Especially for someone who doesn't have the luxury of just go and buy another gun at any time if this one gets screwed up by newbie tinkering on a gun that really doesn't need it. Yo!
