I recently bought a GX E-L2 for filling my rifle on the road instead of hauling a tank around. I like the concept of just filling the rifle directly. I am thinking about a CS3 or CS4 for home use to fill the rifle directly in lieu of the tank. In my case I do not have any big bore rifle nor will I ever. Everything is 177. I do have a couple Walther LG400 rifles that can be filled to 300bar but never fill them past a little over 200bar as they get plenty of shots at that pressure. So in my case everything would be a 3000-3300 psi fill, topping off from around 1500-2000 psi. I don’t shoot everyday (wish I could), more of a weekend warrior and some weekends I don’t have time. The CX3 seems to make the most sense for my needs but the CX4 would prob last for ever with my use. Just curious what others think who own the CX3 or CX4. I like the CX3 price better but have the funds to buy either And don’t mind spending more if it’s worth it.
GX CS3 or CS4 for filling rifle

CS4 will fill faster and last longer. Just don't over grease it. When you get it make sure the fans work and the water flows. Have the old version that I bought used and the fan had never run, wires weren't plugged in properly.

For your needs, the CS3 should be fine. Yes, the CS4 will fill faster and will fill to a higher pressure, but if you don't need those features, why pay for them?
GX Pumps has a sale going on the CS3 right now, brand new for $300.00! You have to contact them through their website to get this deal, but it's a pretty good savings and may be the best route for your needs.

Don't the cs4 handle larger tanks easy vs the cs3 that don't ,?
If the cs 4 is on the short list and in your pricing range may as well get that and be a tad more fill / future proof or find you wished you did ..

Had/have a 3, now have a 4. I've used it to fill two rifles almost daily and I still haven't reached two hours in the almost three months I've had it.
The 4 fills much faster, and quieter, than the 3. Worth the extra $$'s.

Look up colt1900 on this forum. He sells refurbished one with a warranty from him at a great price. He also services them so you got a reliable person to talk to if you experience any problems. I have bought several parts and compressors from him with no issues. Tell him I sent you!

Just curious if you have ever done any filling directly with a tank . . . it is almost instantaneous, and silent (except for the venting, but a well placed washcloth can improve that greatly). I have done both, and find the tank to be far preferable to direct filling with a compressor, no matter how nice or well suited.
I agree a big tank might suck with all .177 guns, but a nice 2L tank can be heaven. And it would pair wonderfully with a CS4 . . . just something to consider in the future.

I have an E2 & CS3i I like them both but the E2 is more portable. If I could go back in time I think I would have bought the CS4i for the higher fill pressure, faster filling & loner duty cycle. @BrazosbyNemo already has tank(s) even though doesn’t want to use them at this time. The CS3 is only rated for tanks 1.5L or less I think.
Bottom line I’d vote for the CS4i with the internal power supply

I do have a carbon fiber 4500psi tank. A Tiger shark from Airtanksforsale.com. I am just thinking I don’t need it. I can sell it and not worry about having to fill a tank, moisture, etc. So far I have only used the E-L2 to fill up my RAW Micro Hunter from around 100bar to a little over 200bar. It only takes 2 minutes 15 seconds and the pump doesn’t even get hot. Granted the rifle only has a 210cc tank. To fill a tank on a reguler bases you kind of need a decent pump. Then you need all kinds of contraptions to filter/trap the water. When I got into this years ago If you had a PCP you had to have a tank. With these new smaller pumps I wonder why I need a tank. I do have a couple steel scuba tanks that are nice for filling 10M air cylinders and 4 rifles that use them. So maybe the CX4 would be the way to go as filling a couple steel scuba tanks to 3000psi would be easy work and two scuba tanks would last me a few years.

I agree or understand everything you said, except for your comments on managing water out of pumps. While it definitely is an issue with the extended run times of filling tanks, it is still an issue when filling guns directly from a compressor. While it is true that these powered pumps stay cooler with the shorter runs, the air charge leaving the pump will still be getting hot towards the end of the fill, and that warmer air charge will carry water vapor into the gun that will later condense out when it cools to ambient. It won't be much water from any one fill, but it will build up over time.
Ideally, you would still use a desiccant filter when filling a gun directly from a powered compressor - it can certainly be a smaller unit, but I would still be using one. That will extend the fill time some, but greatly improve the air quality for the gun. As far as filtering for filling tanks, the filter might need to be larger, but it is a simple manner to source and use a decent one for reasonable price.
For direct fill of guns, I'd consider this filter: https://www.amazon.com/dp/B0BTYXBKCJ

I direct fill my pcp to 250 BAR, 0.3 liter, but always use a filter... large Tuxing... see picture. I did buy a 1.6 liter bottle... Orcair from Amazon so I can extend my range time. It is DOT certified and I am satisfied with it. I use the CS3 and attached the external power to the compressor. Takes under 25 min to refill the tank, or under 10 for direct fill. I have 11 hrs to date on the compressor and no issues. Bought the extended warranty from Amazon, just to cover the bases.
