Things I liked:

This air filler adapter was purchased to replace the original one. The original would not fill the rifle above 220 bar. The air fill adapter is priced very reasonably for the precision that this thing is built to.

What others should know:

These parts will distort over time with normal use. When I measured to bore where the fill adapter fits down over the tank input stem, it was 0 .3 mm out of round. So you should plan to replace the air filler adapter after so many fills. I used my rifle for about 2 years before I started to have problems. My guess is that something like 500 rounds might be the time to inspect the adapter, if you have the correct measuring tools. I use a snap gauge and a micrometer.

Things I liked:

Brass. Never rusts!

Things I would have changed:

The male threads were so buggered-up....... that the product was unusable out of the box (ziploc bag). I rebuilt/chased the threads. Also.....the interior of the T-bar........ circumferentially (360-Deg) are a bit crude/rough. It may need to be rehoned and rouge-polished..... so as to circumvent any leaks.

What others should know:

Air Arms.... and subsequent products (usually) are extremely precise/polished. This particular product .... is a paradox (from the norm) of Air Arms.

  • Warren from USA asked:

    I ordered the hill pump MK 4 is this the adapter I need to use to fill up the Air Arms SS510? I'm new to the world of pcp's and want to make sure I got everything right so when it get's here I can start shooting. In other words I want to make sure I get the right stuff so I don't have to order something I need and have to wait for it.

    • Val from USA answered:

      You don't need this adapter since it already comes with your S510. One way to know for sure what adapters you might need is to use PCP Hookup tab on the PCP airgun tab. You select source of air (like HIll pump) and this web site will tell you what adapters you need if any.

  • Jeffrey from USA asked:

    I just purchased a .177 cal Air Arms (AA) Alfa Sport Pistol. It came with this AA Fill Adapter. What other product do I need to connect it to a standard SCUBA tank with K-valve and D-yoke?

    • Val from USA answered:

      Have you tried PCP Hookup tab on the airgun page? That will tell you if you need any connectors!
