Air Arms Fans....

I have an S510 FAC Carbine superlight .22 and an S400 Carbine Superlight 12 ft/lb .177. 

Love them. I use both for Starling and pigeon control on a few farms. The S400 probably gets the most use. It is deadly accurate (pun intended) out to 60 yards if its not to windy. I smacked two pigeons in the temple at 50 yds last Sat. It gets 30 very consistent shots from a 180 bar fill and is ridiculously light. 180 is the start of the s400's sweet spot and it shoots like a regulated gun for about 30 shots. 

The S510 is also incredibly accurate. Last Sunday I was blasting starlings with a bipod mounted and rested on the hood of my truck out to 87 yards I think it was. It wasn't even challenging. 

If I had to say something bad about them it would be that the FAC S510 is a bit of an air guzzler. It only gets about 20 really good shots before I need to refill it. That is not an issue for me but I can understand how it may put some people off. I can't think of a single thing that I don't like about the S400. Maybe the safety. Ya the trigger blade does seem like a stupid place to put it but in all fairness to air arms it is very practical and to be honest it has never caused an issue for me. In fact I have never heard of it being an issue for anyone. 

I really like the simplicity of these guns and they are extremely reliable. I' e had mine for years and they get used every week. Haven't had a single issue or malfunction yet. They just keep on working. Both are unmodified bone stock. Just took em out of the box and started killing things. 

For what they cost compared to some of the other brands I don't see how you can go wrong. 
 
I've got an s510 FAC as well with a NC LDC on it and the only bad things i've got to say that is is long and heavy. It will shoot JSB16gr on high or med with great accuarcy, but I mostly use med and get about 4 clips before i have to re-fill. I've just started exploring the option on moving on to high power and the testing at short range has almost been pellet on pellet (25yds). I have been using my Cricket for the longer stuff 50 - 112 yards, but wanna start sharing the wealth. I did notice that in low power a can't find any pellet that will yeild better than an inch at 20 yards (13gr to 21 gr).
 
AA S-510 F.A.C.
Love it! It is a solid, reliable shooter that continues to impress me and outshoot more expensive models that have come and gone in my collection. I find it comfortable to shoot, handle, and carry. IMO, it is one of the best bang for the buck rifles you can get! 
If I had to come up with a complaint I guess it would be that it is a little tedious to clean. 
 
I have owned an S410 Carbine .177, an S410 TDR .177, an S510 Xtra .177 and an S510 Ultimate Sporter Xtra in .22.

I think Air Arms rifles are better suited to the UK maket. The high power guns could really do with a regulator and a larger capacity bottle. That said, I don't think there are any guns out there that are more reliable and well built. You can't help but love them!
 
S200 single shot in .177 and an S410E (FAC) repeater in .22.

Both are very accurate, especially the S200 which has a CZ barrel. I don't know which barrel the 410E has.

I especially like the .177 S200 which shoots at about 13 fpe, which I find to be a sweet spot for airguns.
The 410E is a bit nose heavy due to the long airtube and shroud, but the stock makes for a really nice feeling cheek weld, I like shooting it. When I bought it about a decade ago it was significantly cheaper than FX, Daystate and other PCP rifles, but about as accurate.
 
I have a S500 extra fac in .177. I use it to shoot Field Target. Though we always want a better shot count I can't complain with the results of this string.

Of course what's a tight spread worth if the gun isn't accurate? Here is a 5 shot group at 50yds.

That's .347 inches c-t-c. It could have been smaller if I was a better benchrest shooter.



Last but not least, how could you not a love a gun with such a nice stock.

 
I have a S510 Ulimate Sporter FAC in 22 and I have also had one in 177. I absolutely love the 22 caliber very versatile piece of equipment.

It has taken me almost a year to get every thing just where I like it, but because on that 50 yards it's pellet on top of pellet and at 100 yards I normally hold 1.5 to 2 inch groups. I believe I could get the groups tighter if it was a regulated air rifle.

I mostly used it for target shooting but it is setup for garden pests and hunting. I was able to kill a woodchuck at 55 yards this spring with a head shot and kept him for destroying my garden this year.

I'm slowly getting ready to do some Field Target but first I need to make some changes on the rifle. It's a little front heavy for FT but I'm sure it can be done.
 
I have recently purchased and returned a FTP 900. Loved the rifle for the first thirty shots then started to notice that the match trigger was getting progressively stiffer with every shot. Spoke to Air Arms on the phone and they told me to return it to the point of sale for a warranty repair, brand new rifle (1600 GBP) not happy. The turnaround time could not be determined and in the end my RFD (point of sale) gave me a full refund. Have had a Daystate Wolverine "C" in 177 for twelve months and has been faultless.
 
AA is well aware of the issues with the FTP900. 
I personally do not like the safety ( I don't like safety's at all) ON the trigger blade. The old style 16mm shroud worked much better than the newer 20mm. A bit of an airhog. IMO the old style bolt actions were much better. Their springer's seem still decent except the one batch that they used a different epoxy that didn't hold on the TX200, they did go back to a good enough epoxy asap. They do have a great fit & finish. Their FTP 900 is one of their best looking rifles but they released it with bugs (that does happen to most large makers sometime though), I've heard they now have most of the bugs worked out of that one now.
Pretty rifles.
