Hill Pumps MK5 PCP Pump with Dry-Pac Kit 5128-555

I bought this as an entry into filling PCP rifles. I received the MK5 pump which is supposed to be easier than the previous versions, well if it is easier then I’m glad I didn’t have an earlier mark of pump. It’s not easy, even using the suggested technique to fill a rifle from empty would be very hard work (tea breaks are needed), but it’s more manageable when used to top up an air rifles tank. On opening the box it needs assembly to be ready to use, the instructions are simply and I put the pump together in 5 minutes ready for testing. My rifle was at 140 bar and after 30 pumps it’s was back at 200 bar, I haven’t tried to get it up to the max of 230 bar as the effort does increase and I will not lie the sweat was starting to drip onto the pump. The pump feels extremely well made and the version I purchased was with the dry pac option, which I would recommend to protect your rifle from a build up of moisture in the rifles tank and shortening its life. The hills pump is not cheap, you can buy a scuba air tank for the same price, but then you have to go somewhere to get this tank refilled, and also tested every few years from manufacturing date. The other option is a high pressure compressor, these can range in price from £200 to £5000, I did look at these but I don’t shoot often enough to justify the cost of purchase and the hassle of servicing the compressor after so many hours of use was also a concern. So I purchased the hills pump, is it an effort to use - yes, is it simple to maintain - yes and that’s why I am very happy with the hills MK5 pump.

Good kit for self-sufficient air supply. Not difficult to operate at all, why the moaning?

Good quality

I'm a new hobby air rifle owner; not used a PCP hand pump before; had an initial problem with filling the in-built gun canister; discovered 1 O-ring was defective on nozzle but the product comes with spares so switched it over and it works OK; When I start to pump I have to push the nozzle in a couple of times but after a few cycles the pressure builds and the air valve locks and it fills good and proper. I use the pump to keep pressure topped up and whilst there's chatter online, bricks and mortar shops, and on YouTube about how hard it is to use a hand pump, for me, it was no problemo and I'm no gym freak either. It's actually really easy to pump, and it enables autonomy / bug-out freedom from unnecessary and inconvenient scuba tanks. Build quality is robust. The speed of delivery was excellent. I would recommend this.

This is an extremely solid and very high quality pump. Designed to tolerate pressures 100 times that of a car tyre. Bought from here it was supplied with 2 of the dry pacs and could not find better price anywhere. Delivery was fast and packaging top notch. The filling adapter for my Daystate Wolverine fitted into the hose connector and I had to remove the flow regulator screw from the Daystate adapter which is there for use when filling from high pressure sources such as compressors and p.scuba tanks. It's a good old workout to get the cylinder from 150 bar to beyond 200 bar but technique is important. I straighten my arms, fix my torso and bend at the knees so my body weight does most of the work. As a previous reviewer said, it is best to use the pump to top up the pressure in your rifle rather than run it down near empty and recharge. Overall I am extremely pleased with the quality and performance of this pump.

This pump is very well manufactured (in the UK) and with very clear instructions for assembly and maintenance. The Dry-Pac feature is an essential and quite well engineered. It could have done with a cap to seal the inlet when not in use to preserve the desiccant material (which I think is molecular sieve). Takes just a few pumps to top up my air gun. Definitely worth the price.

Minimal assembly required, sturdy construction, simple operation. Just make sure you tighten the hose connectors enough. I can't comment on the accuracy of the pressure gauge more than to say there was a small discrepancy between the pump and the gauge on my rifle (pump read higher). Use with the "dry-pack" of moisture absorbent beads to ensure that you're filling your rifle with air that's as dry as possible. In use, it's pretty hard work, but just how much effort will depend on the size of the cylinder in your rifle. It took me about 3 minutes to pump 50shots worth of air into mine. Nowhere as convenient as a diving cylinder when you're out at the range or in the field but for filling up when you're at home, it's a really cost effective option - especially in these days of social distancing, lockdowns etc.

I purchased a Hill Air Pump MK4 to charge my BSA PCP air rifle, going against advice from friends and gun dealers that it was too slow and arduous to use a pump. The prevailing advice was to purchase a diving bottle but I wanted to be completely self-sufficient and avoid the expanse so I went with this pump. I found it very easy to connect and surprisingly quick to charge: From 100 bar to 230 bar in a few minutes. Obviously it takes some effort to operate the pump but no more than it does to pump the tyres up on my bike. I'm really pleased with the build quality and the performance - nice product!
