The Air Arms S510 pre-charge pneumatic airgun is manufactured in England and is one of the mainstays of the Air Arms family of airguns. Commonly referred to as the S510 Xtra (extra performance) it is available with a few different stock options as well as either .177 or .22 and .25 calibers. In the USA it can also be seen as the Air Arms S510 Xtra FAC where as FAC stating the airgun is full power and not sub 12 FPE. Here we look at the full length version as it is also available as a carbine.

Stock options are available in Popular (stained brown or hunter green) as well as available in Walnut. The Monte Carlo style stock has a soft rubber butt pad giving it a 14-1/4″ trigger pull, fine detailed checkering, and a decorative pistol grip end cap. The blueing on air cylinder is a glossy finish and simply spectacular while the receiver and fully shrouded barrel will take on a more satin finish and again, very high quality not seen from most manufactures.

The Air Arms S510 doesn’t include open sights (which I prefer not to be included) and will need a scope mounted to it’s 11mm rails machined into the receiver. To get the most from this air rifle, it needs a high quality optic.

The trigger on the Air Arms is a 2 stage and is highly adjustable. The length of pull on the first stage can be practically elliminated while the second stage force lightened to just a feather light pull. Be sure to read the instructions carefully if adjusting the trigger or have it done by a qualified gunsmith. In front of the trigger is a gauge giving the user a reading on how much pressure is left in it’s 231cc cylinder, which when filled to it’s maximum pressure of 200 bar provides a high shot count.

The Air Arms S510 is a non-regulated airgun and comes with a power adjuster located forward the cocking lever on the righ hand side. On the opposite side are markings giving you and indication on where the power level is set. A little adjustment can have a big effect. Shooting JSB 15.89 grain pellets we were able to adjust velocity from the middle 400 FPS to the upper 900 FPS range. Depending on your style of shooting and your needs, you may want to have installed an after market regulator, although out of the box shooting at high power this air rifle did extemely well.

What makes the S500 different than the S510 is that the S510 is magazine fed. The magazine is not self indexing, that is accomplished by means of a mechanism in the rifle, so loading is very quick and easy with no springs inside the magazine to deal with. We found the magazine very easy to install and remove quickly but still have a good fit. From our shooting test it also performed flawlessly.

Filling the Air Arms S510 is by way of a special Air Arms brass adapter (included with the rifle) that attaches to the end of the air cylinder. It’s location is covered by an attractive aluminum decorative cap. Although the connection works well it would be nice to see a standard Quick Connect type connection in the future. Be sure to read and understand the instructions before filling the air rifle.

We filled the S510 up to it’s 200 BAR maximum and headed to the chronograph with a tin of JSB 15.89 .22 Caliber pellets. Excellent results as you can see below shooting 40 rounds.

Next we took the Air Arms S510 back inside and mounted an MTC Genesis LR 5-20×50 to prepare for an accuracy test. From our test on the chronograph we could see a 200 Bar fill may not be the sweet spot for this rifle, so we gassed it up to 175 BAR and headed outside for an initial sight in.  We placed a target at 25 yards (keeping it this close just due to the heavy winds we were having) and shooting off a modified rest/bag set up took our first shot hitting right close to the Bullseye. You just have to appreciate when that happens and only a few shots later we were on target.

We went back inside and filled up the S510 to 175 BAR. Again not a full fill but we felt this level would put the rifle in more of the middle zone we saw from the chronograph test and proceed to shoot a couple 10 shot groups with great dime size results.

The Air Arms S510 is a great multi-use airgun, with a 43-1/2″ length and 7 LB 14 OZ weight (unscoped) it’s relatively easy to shoulder and with it’s Lothar Walther barrel it is accurate as well. So whether your punching holes in paper, plinking or pesting the S510 can do it all.
