The rifle is overall in very good condition. Cosmetically, I'd give it a 9/10. It's worn shiny in the touch areas. No bad scratches. Aside from that, the only flaw is that one of the magazines isn't 100% reliable. These mags don't have a spring mechanism in them, so they never clip the pellet skirts and the top accuracy is maintained even with the mag. I'm told this is an easily replaceable part, but have not looked into it further. Plan on ordering it from Pyramyd or Air Arms at some point. The mags all have new O-rings. I will include a full set of replacement Air Arms O-rings for the rifle, too. I bought them for the day when it won't hold air any more, but that day hasn't come yet! I don't have the manual for the gun, but the only thing that's not obvious is the lock screw for the power adjuster is below the action, under the stock.
The scope & rings are not included in the $1k price, but I'll include them for an extra $200 if you want them, as I don't have any immediate plans for them. The scope is a Hawke Vantage 4-12x50 with mil dots. I don't remember what the rings are for sure, but I think Sportsmatch. It's currently zeroed for 25 yards with JSB 18.1s. (For reference, the scope currently sells new at Pyramyd for $210.)
It is power-adjustable, which is a nice feature. Dial it down to practice in the basement without needing a super-stout backstop or to shoot with the widest variety of pellets, or dial it up for 30+ FPE and hammering the critters out past 50 yards.
The most accurate pellet so far is the JSB 18.1 followed closely by the JSB 15.89. For expanding ammo, it shoots PolyMag Shorts well and H&N Terminators. It's not picky until you start going above 20 FPE; after that, it only shoots domes really well.
This is the older, unregulated model. I get 35 shots in the sweet spot of the fill with a 2900 psi fill. It's easy to hand pump, as the tube isn't too big.
The TKO moderator and adapter are included. (It has a shrouded barrel, but at anywhere near full power, it still has enough of a crack to perk up the ears of nosy neighbors. WITH the moderator, it's just a "CLICK" and the sound of the pellet hitting the target.
This is my most accurate gun, and the hunter green stained poplar stock is just beautiful. Nice sharp checkering, etc. It will shoot 1/2" groups @ 50 yards with JSB 18.1s if you do your part and have a solid rest on a calm day. As for practical accuracy, I can pop a squirrel in the head every time at 25 yards standing, while braced on the door stile.
The ONLY thing I don't like about this gun is that when moderated, it's long, about 49". As a benchrest gun or back door gun, it's great, but it's unwieldy when you're bushwacking to find that fallen nutter.
The new regulated S510s are going for $1180 and include one mag. Mags are $60 apiece, when you can find them, so the $1k price with mags is firm. (I'll re-list if it doesn't sell at this price in two weeks)
I will give preference for the first few days to local buyers. (pick up within 20 minutes of Kenosha, WI) If it's not sold after a few days, I'll ship CONUS for $20 UPS to a commercial address. $25 to a residential address. I would consider shipping to Alaska or Hawaii if I can't sell it CONUS.
Payment type: If in person, cash. Otherwise, PayPal, money order or check and I'll wait for it to clear before I ship.
Message me with any questions, and we can talk on the phone if you'd like.
