    By Jesse from USA on 2008-03-29 02:00:05

    Things I liked:Can be used for filling 3000psi Paintball HPA tanks without the need to purchase additional fittings.
    Things I would have changed:Better instructions: The pump came with minimal instructions. No mention if this pump is capable of continuous use, or if you must only pump for 5 minutes then rest for 15.(I am assuming the latter, just to be safe.) And a couple minor things... The bleed screw, although fully functional, takes several turns to open completely. A bleed valve that opened with a 1/4 turn would be a nice luxury. An intake filter with a replaceable paper element for use in dusty conditions would also be a nice addition.
    What others should know:I cannot comment on how this pump works with the Benjamin Discovery, as it was purchased for the express purpose of filling 48/3000 Paintball tanks, which it seems to work well for. When filling a 48/3000 HPA tank, 5 minutes of paced pumping will give around 250psi increase.(will vary with tank size) The product description states that it has a "Moisture filter", but it appears to only allow the moisture to condense in the base and then be expelled when the bleed valve is opened.(There may be some sort of internal filter, but I have no intention of disassembling it to find out.) I have used this pump to fill 4 tanks a total of about 8 times over a 2 week period with no failures of any sort. In summing up, I would recommend that it not be used in dusty conditions, but for the price it seems like a well built pump.

    Things I liked:The out-of-the-box compatibility with my Marauder.
    Things I would have changed:The quality, reliability and warranty. The pump lasted a very short amount of time, freezing in the up stroke position.
    What others should know:I'm currently waiting to see if Crosman intends to back their product or not. For what it costs, I feel it should be better made than it is. I can understand now why Crosman only warrantees these for ninety days.

      Things I liked:Lower cost. When it is working, it seems to do a decent job.
      Things I would have changed:Make it reliable. I have had this pump a little over a year. This pump lasted a few months from the factory and I have been struggling with it ever since. The final stage o-rings go out like clockwork. I seem to get between 6 and 20 charges on a Discovery out of a set of o-rings. The manufacturer is Sun Optics. Duane at Sun Optics seems to want to make good on the product but has yet to be successful. He has replaced the inner tube, provided a desicant filter, and sent me countless o-ring kits. I can practically rebuild the pump in my sleep at this point. Duane is supposedly working on a new carbon fiber o-ring to improve reliability. I believe there is a basic design flaw or manufacturing tolerance problem with this pump. Turn-around time from Sun Optics on replacement parts is generally a week or two during which time you are dead in the water with respect to shooting your rifle.
      What others should know:If you like wasting money or if you enjoy rebuilding pumps more than shooting then get this pump. Otherwise, I would try the Hill Pump or one of the tank set-ups. I believe the Airforce pump is also manufactured by Sun Optics so beware. Google Sun Optics if you want to see lots of other complaints from people with similar problems. I'm really surprised the average rating on this pump is so high.

      Things I liked:It works good construction
      Things I would have changed:Longer hose, you have to lay the gun on its side on the ground to fill. I have a 6" bi-pod and the hose wont reach that high
      What others should know:This is a workout if you plan on shooting over 50 shots at a time you might want to consider the scuba tank, I will be getting one in addition to the hand pump. Personnaly you need both.

      Things I liked:Definitely a high quality American made product. First thing I noticed it is HEAVY it's all steel and definitly built for very high pressure work. Excellent design. I never saw a pump with built in heat sinks before and when compared to a chinese made pump you can see which one was built right.
      What others should know:Definitely a pump that will last.

      Things I liked:Quality
      Things I would have changed:Add an air dryer
      What others should know:The pump will need maintenance. You will need to change orings. My pump stopped working (vacuum issue)after about 400 shots (about 15 refills from 1600 psi to 2800 psi.) I had to replace 1 oring and was back up and running. This is the first high pressure hand pump I have owned so I don't know if this is normal. I had hoped to get a longer life before repair, but the repair was not difficult. Make sure you have assembly/disassembly instructions before beginning any repair.

      Things I liked:The pump failed in less than a week so there isn't anything I can say positive about it.
      Things I would have changed:The pump seems to create black gue after use. I'm not sure what causes it but whatever causes it that's what I would change.
      What others should know:I bought this pump for my Marauder .25. The pump failed in less than a week. I do not know what the specific problem is with it but I am very unsatisfied. I am going to exchange it for a Hill pump.

      Things I liked:Good value for the money. Well made. I'm satisfied with this pump.
      Things I would have changed:Maybe a longer hose.
      What others should know:I have two scuba tanks both hydroed and filled to 3100 lbs. I've never used them. I prefer to pump for the excercise. My Bengy pump services three Marauders. Since I bought it about six months ago I've had no problems. Pump five minutes, slow and deliberately. Rest twenty minutes between sessions. It takes a while if you are filling from empty. If you are just topping off its no big deal. Especially if its a P-rod.

      Things I liked:It would pump my Marauder to 2900 just fine.
      Things I would have changed:Wider base, bigger handles. Easier storage. Failed after 3 months of use. Can no longer lift the handles. Feels like there is an intense suction.
      What others should know:The apparent failure rate on this item is not good at all. Would buy a hill or an airforce next time.

      Things I liked:This pump works well. While I know these things are not cheap, this pump is fairly well made and has a nice bleeder valve. You will obtain large muscles from using this thing for sure! In my opinion, a hand pump is a must have for PCP rifles, even if you own a tank. With a rifle like the Marauder, this pump will take you from around 1800 psi to 2800 psi in around 85 to 90 pumps. You will need to take break when you are done!
      Things I would have changed:With time, I feel the price on these hand pumps, along with other manufactures will likely fall a bit. This would be a much better price point in the 129.00 range as opposed to 179.00. Even still, despite many reviews, this pump is fairly well made.
      What others should know:You will want to avoid over use of this pump by letting it get too warm. I you take very large shot strings and deplete the pressure in your rifle too much, you might want to fill part way, take a break to let the pump shaft and mechanism cool, and then start again. The goal would be to avoid placing heated air which will condensate within your air reservoir.
