What is the recommended operating pressure and Dwell for the Onslaught/ Insight?
HPR usually runs somewhere between 170 and 190 psi. Since there is no pressure tester required to maintain these markers, we recommend starting at a baseline of 0 psi and slowly turning your HPR up(1/8th turn at a time) until your marker cycles. Continue to slowly adjust the HPR "up" until you reach your desired chronograph speed. Do not adjust your regulator more than 1/8th turn at a time- doing so can raise your HPR pressure too high which can cause damage to your solenoid.
Dwell should be set~12. The ideal output pressure for your tank regulator is between 300psi and 500psi (depending on fire rate).
Why is my Onslaught/ Insight experiencing low velocity?
There are a couple of different reasons that your Onslaught/ Insight 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 (12) for fine-tuning purposes, this can sometimes lead to unsatisfactory results. Set you dwell back to the factory recommended setting (12) and retest your marker.
3) Pressures- HPR pressures need to be set at a minimum value for the marker to cycle and shoot properly. The factory recommended HPR setting for your Onslaught/Insight is 180psi. Since there is no gauge on the marker and a pressure tester is not required to work on these markers, we recommend adjusting you HPR 1/8th turn at a time and testing over the chronograph to find your optimal operating pressure (velocity).
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 marker's engine and HPR piston will often get your marker back to full performance. Of particular importance when maintaining your marker are the 010 o-rings on the back of the ram and in the brass shutoff inside the engine. These are dynamic o-rings that require regular lube and replacement. O-ring replacement kits and maintenance kits, as well as F1 approved marker lube is available here: Parts Kits and Marker Lube
5) Engine is not assembled/installed properly- this is a common issue because the engine is made up of many parts. Before disassembly of your marker or it's components, be sure to have access to the Owner's Manual for your particular marker. Simple things like the back cap not being tight enough, the engine halves not being screwed all the way together or the brass shutoff not seating properly can have negative effects on the performance of the marker. Keep in mind, most parts of the engine only need to be hand tightened to "snug" and should not be over-tightened and do not need a "thread-locking" solution used to hold them in place. If you have questions about how to assemble your engine, please consult the owner's manual or ask a qualified technician center for help.
6) Solenoid is not working properly- If your solenoid is not working properly, the marker will not cycle with the pressure needed to give you good consistency or adequate velocity. 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.

My Onslaught/Insight 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 your marker and the basic method to fix it:
1) Breech- a breech leak is commonly caused by a damaged seal or bolt tip shaft. First, inspect your bolt tip shaft for deep scratches or burrs. If you find that your bolt tip shaft is damaged, you may have to replace the bolt tip. More commonly, replacing the U-Cup and the 020 o-ring at the front of your engine (volume chamber) will fix this issue.
2) Edge of grip frame/ between ASA and gripframe- 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 gripframe and the ASA, you can remove the ASA and replace the 1x4.5mm o-ring that seats between the gripframe and ASA. If the leak is coming from the cam drive knob area, you may need to rebuild the Cam Drive ASA Main Seal/Support.
3) Back Cap area of engine- if the leak sounds like it is coming from your gas interlock button, there are 2 o-rings seals that should be replaced (1x13mm and 011). If you detect the leak is coming from the edge of the back cap where it meets the ram housing, you can replace the small o-ring seal under the cap (1x2mm). If you detect the leak coming from around the engine, try replacing the 021 o-rings that surround the rear part of the engine (ram housing).
4) Bleed hole- try replacing the 010 o-rings on the ram shaft as well as the 021 o-rings on the outside of the ram housing.
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.

Why is my marker 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. 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.
1) Slow Recharge/ Regulator maintenance needed- to rebuild your HPR, you simply need to replace the Schrader valve and piston o-ring (016). Give all o-rings a moderate application of F1 approved marker lube.
2) Spool engine requires maintenance- your marker works with a series of chambers holding and releasing pressure as the marker cycles. If any of these chambers that are holding pressure become unbalanced or leak, you will see a severe drop-off in performance. It is recommended that you perform an engine rebuild if you see a sharp decline in the performance of your marker. An engine rebuild includes replacement and re-lubrication of all seals in the engine. We recommend that you re-lubricate your engine every 5 cases (10,000 shots) or as needed and that you rebuild your engine (o-ring seals) every 15-20 cases or as needed.
3) 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.
