What is the recommended operating pressure and Dwell for the G6R Intimidator?




(Hint: the G6R solenoid has an LPR operating range between 30psi and 100psi- operating the solenoid outside of this range can cause a leak or damage to the solenoid)

The LP Poppet can lower both regulator settings by about 5-10 psi.

Dwell should be set~6.

The ideal output pressure for your tank regulator is between 300psi and 500psi (depending on fire rate).

Why is my G6R experiencing low velocity?


There are a couple of different reasons that your G6R could be experiencing low velocity. We will start with the easiest to diagnose/remedy and move to the more complicated or expensive fixes. Keep in mind, if you have any issues with your marker, you should first try to perform regular maintenance  on the marker before disassembling the marker. Here are some causes of "low velocity" to check for on your own:

1) Change battery- because the cycling of the marker is dependent on the solenoid working properly, low battery power can have a big effect on your marker's overall performance. Even if your battery meter on the OLED display reads full, you should still try changing the battery  to fix some of these simple problems.

2) Dwell is not set properly- the dwell is adjustable in the main board settings on your marker. Although some people may adjust their dwell out of the recommended factory setting (6) for fine-tuning purposes, this can sometimes lead to unsatisfactory results. Set you dwell back to the factory recommended setting (6) and retest your marker.

3) Pressures- LPR and HPR pressures need to be set at a minimum value for the marker to cycle and shoot properly. The factory recommended settings for your G6R are:

LPR= 80 psi      HPR= 175-195 psi

It is ok to operate your marker slightly outside of these parameters but if you are having velocity/consistency/cycle/breaking paint issues, you should try resetting pressures back to these parameters.  (Hint: the G6R solenoid has an LPR operating range between 30psi and 100psi- operating the solenoid outside of this range can cause a leak or damage to the solenoid)

Most markers are set at LPR80/HPR190 before they leave the factory. Once these baseline pressures are set, you can fine-tune your pressure settings over a chronograph. The G6R Pressure Tester is one of the most important tools for maintaining and tuning your G6R. It is available at your local F1 Dealer or on the F1 Website here: G6R Pressure Tester

4) O-rings- if o-ring seals in your marker are out of tolerance or have worn from use or age, this could have an adverse effect on the performance of your marker. Rebuilding/replacing the o-rings on your markers bolt, ram, back-cap, HPR and LPR will often get your marker back to full performance. O-ring replacement kits and maintenance kits, as well as F1 approved marker lube is available here: Parts Kits and Marker Lube

5) Poppet seal is worn- over time and use, the poppet seal inside your marker will wear. Although this usually takes a lot of time and use, it is something that happens gradually over time and has a big effect on velocity. As your poppet seal wears, you will need to increase your pressures to maintain the velocity you want to play with. If you decide to replace your poppet seal, be very careful to not foul the sealing edge of the body, as this cannot be repaired and is costly to replace.

6) Hose Barb has become unseated- you can check on this small part by removing the back cap of the marker and looking for the small brass fitting next to the screw hole. This brass part is the back of your hose barb. It should be fully seated and not protruding from it's recessed hole. This problem does not arise often but is easy to check.

7) Solenoid is not working properly- If your solenoid is not working properly, the marker will not cycle with the pressure needed to open your poppet valve all the way. This is one of the more difficult issues to diagnose as there is not really a good test other than replacing with a new solenoid and seeing if the issue is resolved. Most people will send their marker to the service center if they have checked all of the other listed issues and they suspect that they may be having an issue with their solenoid. The solenoid is one of the more costly and labor-intensive parts to replace, so all of the other areas of the marker should be inspected and maintenance performed before it is replaced. Information about sending your F1 marker to an Authorized F1 Service Center can be found here: F1 Support 

My G6R is leaking……


Your paintball marker can leak from different areas for a variety of reasons. The best way to detect where the leak is coming from is to air up the marker and listen or use a diluted (mild) soap and water mixture on the outside of the gun to check for bubbles. DO NOT submerge your marker in water and do not over-apply the soapy water mixture. Work in small areas of the marker and dry off the marker when you are done looking for the leak. Do not fire the marker while it is close to your ear (Turn the marker off before checking for leaks). If you can identify where the leak is coming from, you can most likely fix the leak by replacing a seal or o-ring.  Here is a list of common areas where leaks can occur in the G6R and the basic method to fix it:

1) Breech- a breech leak is commonly caused by a damaged or dirty poppet seal. You can replace the poppet seal by separating the 2 body halves and replacing the white seal on the poppet shaft. Be sure to not foul or damage the sealing edge of the new poppet seal or body. This repair should be done in a clean environment. Do not stick a tool inside the body where the poppet seals against the body. If the body is damaged in this area, it cannot be repaired and is costly to replace.

2) Edge of grip frame/ between ASA and gripframe/ between body halves- Most leaks coming from these areas are easy to identify and fairly easy to fix if you have a replacement o-ring kit. There are a number of stationary o-rings inside the marker that allow air to travel to different areas of the marker without the use of external hoses. When maintaining or replacing o-rings, you should also apply a thin layer of F1 approved grease to the seating area and the seal.

If you detect a leak between the 2 body halves of the marker, you can separate the body halves and replace the 1x18mm o-ring between the body halves. If you detect a leak near the top of the grip frame, you can replace the 014  o-ring that seats into the grip frame or the 1x5mm o-rings that seat into the front of the manifold or the 1x4mm o-ring that seats between the gripframe and manifold. It is common practice to replace all of these o-ring seals once you have the grip frame removed so you don't have to disassemble and reassemble the marker the multiple times to fix the leak. If you detect a leak between the gripframe and the ASA, you can remove the ASA and replace the 1x4.5mm o-ring that seats between the gripframe and ASA.

If you find yourself needing to replace these stationary o-ring seals often, you may want to check the output pressure of your tank regulator as high pressure or "pressure spikes" can unseat stationary o-ring seals. The recommended output pressure for your tank regulator with your Field One marker is between 300 and 500 psi (depending on fire rate).

If you have performed this maintenance and still have not resolved the leak issue, you may have a leaking manifold or solenoid. It is recommended that you send your marker to an approved F1 Service Center for diagnosis and repair if you suspect that this is the issue.  Information about sending your F1 marker to an Authorized F1 Service Center can be found here: F1 Support 


Why is my G6R inconsistent at the Chronograph?


Inconsistency at the chronograph can be caused by a few different issues. Some common factors that are independent of the operation of the marker that you may want to consider are:

1) Overall quality of paintballs

2) Paintball size to barrel bore sizing

These issues are discussed in the F1 General FAQ section- you can get there by clicking the link here: F1 General FAQ 

For consistency issues that are related to the operation of the marker, we will start with the most common(and easiest to fix) and move on to some of the more complicated matters.

1) Low LPR/unbalanced pressures- setting the LPR and HPR to factory settings is a good way to start addressing this problem. Set LPR to 80 and HPR to 190. Chronograph your marker. If you are experiencing inconsistent velocity, you can bump your LPR up slightly and re-chronograph your marker. The LPR and HPR settings are sensitive and should not be turned more than 1/8 turn between shots over the chrono or pressure testing. Once you have achieved consistency by adjusting the LPR, fine-tune the velocity with the HPR adjustment. With good quality paint and a well maintained and tuned marker, you can expect to get a string of shots that are all within 10fps of one another. Most paintball fields have safety guidelines that require players to shoot between 260fps and 300fps maximum. 

2) Slow Recharge/ Regulator maintenance needed- While pressure testing your marker, you will be able to fire the marker (remove paintballs and fire only in a safe area around people who are wearing the proper protective gear) and observe how the gauge recovers after each shot. Typically, your gauges should recover very quickly after each shot and recover to the same pressure reading after each shot. If the pressures don't read consistently or there is slow "creeping" happening with your pressure tester gauge, it may be time to rebuild your regulators and reset your pressures. To rebuild your LPR and HPR, you simply need to replace the Schrader valves, piston o-rings and the o-rings on the LPR core. Give all o-rings a moderate application of F1 approved marker lube. The regulator piston inside the HPR and LPR should be clean, have an adequate amount of F1 approved lube and slide smoothly within the regulator housing.

3) Valve Spring unseated- with your LPR removed from the marker, you will have a clear view of the poppet valve spring by looking into the LPR mounting hole. You should be able to see directly through the center of the spring to the white poppet seal. If the spring looks twisted or bent out of place, use a soft tool to gently apply pressure to the spring coil that is oriented towards the top of the marker. The spring should "click back into place and be seated properly.

4) Solenoid is bad/dying out- A solenoid issue can be hard to diagnose but if you have already checked and maintained the other areas of the marker and are still having issues with velocity or velocity consistency, you may have a bad solenoid. Solenoids can be damaged by foreign materials(grease, dirt, o-rings, teflon tape, metal) entering the solenoid and spoiling the internals. If you have tried the other methods listed above to address your "inconsistent velocity" issue and the problem is still not resolved, you may want to send your marker to an authorized F1 Service Center for help.
