EsportsMJJ 1/8 Inch BSP Quick Release Coupler Fittings Charging Adapter Kit for Air Rifles PCP

Was a bit dubious buying an unknown (to me anyway) brand but so far they have fine and have worked as they should.

Perfect adaptor for my Gamo PCP. Needed to adapt a Hills Spartan pump to the cylinder filler.

good

I actually use this as a mount for the insta 360 x4 camera! I use a small adapter for the mirror bolt on the motorbike, attach this, then have a small adapter from male m10 to 1/4-20 (bolt for camera), after I had two mounts snapped and break. This has been used for months now and still works perfectly!

Used with PCP rifle and compressor. Works great !

Needed to add quick release coupler so that I could swap between BSA and Daystate fittings, worked perfectly. Bought another of these for a Weihrauch.

I recently bought a PCP rifle - Walther Rotex RM8 - and also a cheap hand pump. As I discovered most PCP guns require a 1/8" fitting for the coupling adaptor and annoyingly the stirrup pump was fitted with a smaller thread. Good pump for the money but an odd choice of fitting. Anyway, clearly this must be 'A Thing' because there are many 1/8" adaptors available and I bought this one. Which, works perfectly. The thing I do like is the quality as well. Lets be honest here, a PCP rifle is pumped up to around 200 bar which isn't small potatoes. You really don't want the fitting to pop off because the whip effect would nip a bit. So, I was very pleasantly surprised at the quality of this cheap adaptor. And being a Chief Engineer of many years having spend quite a few on saturation dive vessels I know a thing or two about pressurised gases the equipment used. In conclusion, I can't find fault with this adaptor. It's well made, works well and is relatively cheap.

Seems to be a bit rough on a particular gun fitting, so I got another brand which connects better, so OK,but not great
