Benjamin FAH003 Scuba Yoke Adaptor For Benjamin/Crosman PCP Airguns

It is working awesome. Only one thing can be better. The hose is very short .

This is a very simple accessory to use on any Crosman PCP rifle or pistol... virtually all of them work with this setup and your favorite SCUBA tank, preferably made of aluminum alloy with a K-type Valve assembly. I thought that the K-Valve hose fitting off the yoke assembly matched up with the tank's "K-type" valve perfectly, and I had an instant fill up in my Marauder 25-Caliber Rifle. Actual time it took was about 20 seconds, ie to see the gauge on the bottom of my rifle, and the one on the fill-up valve, to read "3 Atmospheres" and promptly STOP there, all by itself.Turns out that when the atmospheres of the source and the object that's being filled up are the same, that parity is reached quickly, and safely: the fill up stops at just less than 3 Atmospheres, and will not budge from there, without fail. I filled up my Marauder rifle and the Marauder 22-Caliber pistol at will, a dozen or more times per weapon, when I went shooting recently, and it worked exactly the same each and every time!The PCP fill-up valve is handsomely either stainless steel or heavily chrome plated (I couldn't tell which it is), giving most of the assembly but for the black, krinkle-finished top (head of the valve) portion--it's 100% black and contrasts 100% with the fill valve and the rest of the assembly, which is either black metal or unpolished metal, your pick. Just the top of the valve assembly in the Crosman "kit" for K-style valves and tank assemblies is bare, or unfinished metal composition. The rest is chromed, polished stainless steel, or a combination of those surfaces and finishes//it looks GREAT! I haven't seen a lot of other tanks and valve kits at the shooting club yet, but I'm sure they all are NOT as nicely done as the Crosman "kit". If they are, then I'm dumb and need a refresher course in humility until proven otherwise I guess, Hah!All in all I rated this K-type valve compatible yoke and filling assembly 5 stars, both for shipping ease from Amazon.com (my PRIME account), and the quality of the product and its great looks, out of the box. If you have a Crosman PCP rifle or pistol and it's qualified to use a system like this, your effort at the shoot, be it a club, outdoor recreational facility for shooting, an indoor facility (like mine is), I think your shooting is bound to take up a high-line for ease of effort compared to the hand pump alternative. A setup like this, for me, is the answer for my PCP weapons, and I won't be going back to the high pressure Crosman pump unless it's an emergency, my PCP system for fill ups fails for some reason, and/or any similar circumstance.As-is, it's the cat's meow for shooting a PCP pistol or rifle, this Crosman "kit"--the yoke and fill valve system for any PCP rifle qualified by Crosman to use it. Cost is a trifle thing to consider when you think of all the hours of pumping it will take with a qualified hand pump to achieve essentially the same results...it's just simply back breaking work if you were to ask my opinion!Five Stars all the way ***** , this Crosman getup is da kind, the best, as good as it gets for the right pistol or rifle. True it's not one of those graphite smaller tanks which hold 4500PSI pressure, but after using this setup I own I see no reason to spend $800-$900+ on a filling system (the graphite one) when this $300 system I have in front of me will kick butt on any fill job I can think of!Wavey Davey - 1-21-2013

Who knew these new air guns required a full platoon of support requirements. This is actually quite the way to go. I have refilled the pressure tube on my Marauder numerous time and the doesn’t seem to be a change in air volume.

This Item worked perfectly as intended. I am happy with it

If you have any air gun that uses this type of connector to add air to the on board tank this is a must! Fills the tank within 2-3 seconds. You need a scuba diving tank and this piece and that’s it. Way way easier than the foot pump!
