My arthritic father (73) cannot work this pump, but I knew that. I can work it smoothly up to my Urban's psi, but it is a workout to get those last 5-750 psi. I'm only dinging it one star for that because I need the exercise anyway. Assuming it doesn't break down the second time I fill the gun (or preferably, ever) I think this is a solid pump.

Easy to assemble. Works with Gamo Urban right out of the box (no extra connectors needed). Pumps up to more than I need, so it gets the job done. Feels sturdy, handle is steel wrapped in a pleasantly squishy grip.

No way around it: it's a hand pump.

There's a reason most videos skip the actual pumping of tanks. If your'e new like me, you need to have a "Air Venturi Double Male Quick-Disconnect Coupling." In order to have use of this thing to try and fill a small tank.

No electricity, No problem. Sturdy Easy assembly

Pump tube heats up, don't worry though by then your'e too tired to continue so take a break or risk wearing out the seals. The area where you place your feet is plastic but it hasn't broke yet.

Air Venture MK4 received. I bought this hoping that it would be the required motivation that my gym membership could not provide and has failed at getting me out of this seating position that i have been in for numerous years now. Yes you need to pump pretty darn hard towards the end but it really is motivational and great too know once i fill the bottle the reward will soon follow!

Pro's - Easy to put together. Very well made pump. If your going to get a hand pump it is important to get a top notch pump, modernized version, reputable unit like this one is. Don't try and save a few bucks on something like this. It will bite you in the end.

Con's - The plastic base that you place your foot on seems a little on the thin side compared to the rest of the parts on this pump. It has NOT broken or cracked i am just filling in this con's section with the observation that you might have when you open the box. That said: With the new plastics materials that continually pop up. The plastics built in durability very well could outlast me! I can see it now......... you will be bidding on this otherwise sturdy pump with a PERFECT INTACT foot pad at the garage sale that my kid has in order to pay for my wooden box and patch of grass on the near by hill.............time will tell. lol

One of the better pumps i have used

Quality pump

By MunchUSADecember 24, 2019

This is the only pump I have ever had, so I really can't compare it to others. I does however function flawlessly. It is easy to pump, I can do 150 pumps in about 5 minutes, which takes my Umarex Gauntlet from under 2000 psi to 3000 psi. The plastic base is made from a very strong plastic, and I have no worries that it might break.

Well made, efficient.


By StephenDecember 2, 2019

Works well with good air dryer. Plastic base looks shady but it has held up for several refills.

Easy to top off tank with

Plastic base

I bought my first PCP marauder which wasn’t cheap but I did not want to spend more money on a bottle or a compressor that was more than my rifle. From 2000psi to 3000psi it takes about 80-100 pumps. I find it very easy to pump. I do take breaks and feel to make sure the pump isn’t getting too warm. I recommend this to anyone who is first getting into PCP

We use this pump to test some of our scientific products. This pump works perfect!

By Elmont USAOctober 23, 2019

Pumping is harder than I imagined but it does the job. I’ve learned to use my pump more as a top off then a refill to save time on the range. Overall I’m pleased with this product

Ok I first bought the Airforce 3 stage pump to recharge my Condor SS .25 cal. I have to say the last 500 PSI from 2500 to 3000 was not fun it took around 115 pumps to go from 2500 to 3000 and I really had to drop my weight on the pump to make it there. I also have a 100 C.I. fill tank “Guppy” I found out after a little research I should have gotten the Air Venturi MK 4 for two reasons 1. It has air filter, 2. It will pump up to 4500 PSI the Airforce would only go up to 3500 which would not allow me to refill my fill tank to 4500 PSI, also after a little checking I really felt the need for the moisture filter.... so I contacted AirGun Depot and made the exchange for the Air Venturi MK4 and I can not believe the difference to go from 2500 to 3000 on the Condor take 75 to 80 pumps and the effort is no problem at all. I have changed my mind about getting a compressor for now as the pump is no problem at all even topping off my 4500 PSI Guppy is easier than topping off my Condor to only 3000 PSI with the Airforce pump. It makes me think the Airforce pump was defective because there was so much difference in the two pumps. I pain on getting a Texan .45 and I will get a compressor then, but until then I really don’t need one.

Much easier to use than other pumps, the moisture removal is a must. topping

The only thing I didn?t like over the other pump is the foot pad is plastic I am old school and metal is better in my book, hopefully time will prove me wrong.

Does this pump require less strength to pump your gun? I read about one pump that cost $300, but claim that a 140 lb. Person could fill a marauder, with no problems, that it actually took have much less ,1/2 the strength that regular pumps need? Unfortunately I did not save the site, or how to get back to it. Does anyone know or have heard what I'm talking about? Thank you ..Robert Neuman

asked Dennis Buckley

Where did you buy the adapter for your air rifle?

asked Bruce

I have a Benjamin Marauder .25 cal rifle and a Benjamin Marauder pistol. I have went through 3 Benjamin Pumps in less than 8 months. I am going to try the best now. What additional auxiliary connections will I need for this pump to work? And if not the Hill Pump MK4 what do you recommend for a solution for my problem?

asked Willie Harper from USA

You should not need any other adapters to pump up your Marauder. The pump has a female Foster fitting which should work on the male Foster fitting on your Marauder.

Sidney from USA

You won't need any adapters if you get an air ventri g6
