Installing the L7

Required Tools:
- 1/8th Allen Wrench
- Paintball Gun Grease

1. To install the bolt you will need to tear down the gun as normal to remove your old bolt.

2. Remove your old bolt and old bolt stop from the firing can.

Recent Update:

We recently have made a change to the "back plug" of the L7 bolt. The newer style of back plug does not have a screw that tightens down the back plug. We found that too many people would over tighten the back plug and break it. So we tightened up the orings and removed the screw from the design. This new design make's installing the plug very simple. You just push it into the back of the can.

If you have the older style of plug we ask that you contact us and we will send you the newer style for free. Please send requests for a new plug to support@techtpaintball.com

We do require that old plugs be returned to us, but we will send you the envelope for returned shipping.

Overview

The L7 installs into all Ions or similar markers pretty much the same way. The back plug seals back of the firing can and you replace your current bolt stop and bolt head with our L7 parts. The back plug is needed on the newer bolt out back bodies that Smart Parts has released as well.

 

This set of instructions is for the first generation Ion type markers.

Original Ions, Sp-8, Epiphany (newer markers see instructions below)

1. Look at your back plug. If it is version 1, loosen, but do not remove the screw on the Back Plug so that the oring is not compressed. We would perfer that you contact us for the plug update, but for the mean time you can use the version 1 plug as long as it is not damaged or damaged during installation.

2. Apply a very small amount of grease to the o-ring closest to the front of the back plug. Apply no grease to the oring located furthest from the front.

3. From the front of the firing can insert the Back Plug into your firing can. The plug should slide easily down into the back tube portion of the firing can. Push the back plug into the tube as far as it will go.

Version 1 plug installation

6. If youPlace a wide flat head screwdriver down into the slot in the front of the back plug. Now place a 1/8th allen wrench into the screw on the back of the bolt plug, from the outside of the can. Holding the screwdriver in one hand, and the allen wrench in the other, tighten up the back screw. Do not over tighten. The screw only has to be slightly snug. If you attempt to make it crazy tight you will break the plug slot. Breaking the back plug can be dangerous. If you feel that your back plug is broken or may have cracked please contact us for a replacement plug immediately. Do not attempt to play with a cracked or broken plug. If broken, the plug could cause injury or death. AGAIN.... do NOT go crazy.... snug will work, tough guy.

7. Apply lube to the inner and outer bolt stop orings. A nice thin layer will do. See picture above.

8. Place the bolt stop into the firing can with the larger concaved face pointing towards the back of the firing can.

9. Lube up the bolt head. Apply a nice coating of grease to the entire outer surface of the bolt head, including the tail that comes in contact with the bolt stop.

10. Place the bolt head down into the bolt stop.

11. Rebuild your marker as usual.

This set of instructions is for the newest generation Ion type markers.

Ion XE, Sp-1, EOS

Overview

Basically the same as installing it on the older version markers, but in the newer ones you do not need to tighten the back plug....because you can't get to it.

1. Look at your back plug. If it is version 1, loosen, but do not remove the screw on the Back Plug so that the oring is not compressed. We would perfer that you contact us for the plug update, but for the mean time you can use the version 1 plug as long as it is not damaged or damaged during installation.

2. Apply a very small amount of grease to the o-ring closest to the front of the back plug. Apply no grease to the oring located furthest from the front.

3. From the front of the firing can insert the back plug into your firing can/back cap. The plug should slide easily down into the back tube portion of the back cap. Push the back plug into the tube as far as it will go.




7. Apply lube to the inner and outer bolt stop orings. A nice thin layer will do. See picture above.

8. Place the bolt stop onto the front of the back cap. With the XE version of the bolt stop the direction does not matter.

9. Lube up the bolt head. Apply a nice coating of grease to the entire outer surface of the bolt head, including the tail that comes in contact with the bolt stop.

10. Place the bolt head down into the bolt stop.

11. Rebuild your marker as usual.

Dwell Set-up for MAX SPEED AND EFFICIENCY.
For max speed and air efficiency you must fine-tune your dwell setting. This is done quite easily, however if you are unsure how to do this, go to your local pro shop or check out our Ion 101 DVD.

BE SURE TO HAVE A FRESH, FRESH, FRESH DURACELL OR ENERGIZER LITHIUM ION BATTERY. THEY ARE THE BEST. DO NOT USE A CHEAPO/OLD BATTERY OR YOUR RESULTS WILL BE OFF.

There are two ways of setting up your marker. The one that I am going to talk to you about first is the slower less frustrating way of maximizing your bolt, but it makes for an easy set up. The second method is great too, but it can be frustrating....its up to you.

The EASY Set-Up

1. With the new bolt and QEV installed start your dwell out at like 30. Different boards may vary in settings. Many people would call this a dwell of 30. Set your input pressure so that you are shooting the needed velocity.

2. Now go play a game. I know that your dwell is probably way too high, but that's ok, I want you to see how well the bolt can shoot with a higher dwell. While playing see if you notice shoot down at high rates of fire or inconsistent shot velocity. If not....you're good to lower your dwell.

After a game or two of good shooting try lowering your dwell by 5 flashes, and then go play a couple more games. Back on the field, if you don't notice a negative difference in how the gun was shooting, go back in and lower the dwell by another 5 flashes.

The idea is to try to achieve the lowest possible dwell and also have the highest level of consistency and accuracy. There is no magic number here, you just have to do some trials at different settings.

4. Once you make an adjustment and notice that the marker is not shooting as well as it was at previous settings you need to up your dwell by some number. I typically will up the dwell back to the last good setting you were at and then start going down in increments of 1 flash instead of 5. After each game that the marker is shooting well, lower your dwell by one. This will allow you to zero in on that perfect number. Once you find that exactly number where your marker performance begins to drop off or shoot poorly, up the dwell by about 1-3 flashes. This will give you great air efficiency and great consistency.

If this method didn't work so well....try this one.

The Low to High Set-Up Method

1a. With a stock dwell setting (smart parts boards = 52), I like to first re-chronograph the marker to the desired FPS. This allows you to find the lowest / correct pressure that your marker wants to operate at with your new bolt.

1.Now by lower your dwell all the way to the bottom (lowest/fastest) setting.

2. With a barrel bag in place, air on the gun, and no paint loaded...start trying to dry fire the gun with the eyes off. Most likely the gun won’t shoot.

3. Now increase the dwell 1 flash at a time until you can get the gun to shoot when you pull the trigger.

4. Now that the gun is firing, hand load 10 paintballs and see what you are chrono graphing at. It’s probably going to be pretty low. If you try to dry fire the gun quickly, you will probably hear that the blast of air coming out is erratic sounding.

5. Continue to shoot 10 balls over the chrono and adjust your dwell up by one flash after every 10 balls you shoot. What you are doing is finding the absolute minimum dwell setting you need in order to chrono at the right velocity. Once you find that setting that results in 280-300fps it’s always good to increase it by 2-3 flashes so that at high rates of fire you don't get shoot down. **If you just cant seem to get your velocity high enough, you may need to up your pressure 10-20 psi and start over.

** NOTE: The lower you set your dwell the more gas efficient the gun will be, but it will also be more inconsistent. The higher it is, the more gas it will use, but you will see better accuracy and consistency. It’s up to you to find the balance that you like most.

Please don't ask what the best settings are. Each gun is a little different, so there are no settings that are perfect of every gun. If you follow the above instructions you will find your guns perfect setting.

Free Advise: Grease your marker and change your battery often. This will increase your guns accuracy and overall performance. I suggest greasing the bolt every 5000 to 10,000 shots. We've gone 50,000 shots with out greasing the bolt. It still worked fine, but for good performance and long oring life.....grease it after 2-5 days of play.

For best results, use our bolts with a Quick Exhaust Valve (QEV). If you don't, you will not be able to lower your dwell as much. We prefer the ones made by Planet Eclipse as they seem to have the best flow rate of any QEV.

Lastly...go shoot some people.

If you have any suggestions that may help people install or set their marker up even more, please email me at todd@techtpaintball.com

Good Luck,
