Is there a difference in performance from the cheaper $50 pumps compared to a higher end pump like the mk4? I have a yong heng and a cheap $50 pump as a back up I live in a condo and when I want to fill my tank I need to go down the street to my shooting club so I got the pump to pump the guns when I have free time. Should I be investing in a mk4 type of pump I hear the higher ends do a better job. Any information would be greatly appreciated and hope everyone is staying safe.
 
I just got into PCP air rifles. I bought a Air Force pump for $240 with tax and I bought also a $75 hand pump from eBay. I don’t know if I’m doing something wrong with the Air Force pump but my gauge is way off. It’s reading 50-60 bars more than my gauge on my air rifle. The eBay one reads perfect, it has a filter on it also as the Air Force pump does not.

May be you should rethink if there is really the need to have a hand pump as back up. I used to own a Hill Mk3 pump and I sold it after getting my Yong Heng. For me, the best back up is getting Yong Heng spare parts and O-rings in advance so that you can fix it quickly if it breaks down. The construction of the compressor is very simple so rebuilding it is pretty easy. I can replace any parts in the head within 30 minutes. As said by another member above, I won't go back to hand pump again because there there is no practical way to get dry air out of it.

They both compromise and ruin your gun by putting moisture in it. Waste of time and money let alone your gun will be destroyed

Not entirely true, that applies more towards cheaper PCPs with steel tanks. Every PCP that I own has air cylinders with polished aluminum walls. The reg bodies are aluminum, and the only steel that can rust inside them are the snap rings, but I have used my Hill MK4 in wet conditions and I have not seen a snap ring rust yet.

I am mode concerned of the long term mineral deposits. You will see it come out like 🧂 salt rocks if they loosen. Depends on the air conditions. If you take a bore sight and look inside you should have some junk in there as you have not processed that air prior to entry. 



I’m more anti pump over most people, so I agree with the idea that it probably works fine but 9/10 people abandon pumps anyway because they are too time consuming and no fun. Also, it so happens that hand-pumping does introduce your rifle to the elements sort of speak from the inside out.

I've never seen any corrosion or signs of problems caused by moisture from a hand pump. I've been deep inside of every PCP that I have owned, I make parts for all of my rifles, and if there was any damage caused by moisture from my Hill MK4 - I would have seen it. I have filled my P-Rod with my Hill MK4 from under a tarp in heavy mountain rains, and then let them sit for almost a year at ~1000psi - no issues whatsoever. All that I have seen has been some surface rust on one of the outer screws.

I'm also aware that not everyone can work on their rifle. If you're the type of airgunner that shoots infrequently, and are not able to service the rifle yourself or have it serviced for you, it might be a wise idea to avoid rifles with non-stainless steel tubes / plenums with cheap hand pumps that do not have some sort of integrated moisture separator. Buying a compressor also translates to compressor maintenance.
