Important Info #1:
The Bk, like all Automatic Electric Blasters (AEB), cycles best on a fully charged battery.
Make sure your Lipo Battery is fully charged, or you may experience some cycling issues.
More Cycling Info:
If the timing of the cycling gets off and is consitently not feeding properly, try resetting the cycling by holding down the trigger for 30 seconds. You’ll hear several beeps, and the cycling will reset when you release the trigger and the timing should be set to factory defaults.
Lubrication:
If it seems like the return of the bolt forward or moving back isn’t as fast as it used to be, applying some lubricant to the moving surfaces can help.
Magazine Release:
Sometime factory tolerances can vary batch by batch.
This will help the Magazine gravity drop much more easily.
Stock Stability:
Due to the entire blaster shell being blaster, the stock thread and mount can often loosen up.
The Buffer Tube of the stock can be made more rigid by rotating the tube until the tube until is as tight as you can get it with the orientiation of the tube being lined up.
Then tighten the ring on the tube threads as tight as you can against the blaster.
You can use a wide mouth pair of pliers to help get a grip on the ring and make it tight.
Adjusting Power
The BK is designed with quick access to the main power spring via a “cap” that can be twisted.
To access this, remove the battery and stock body.
Then remove the Thumbscrew just below the Stock Buffer Tube Mount.
Rotate the whole stock assembly counter clockwise and remove the stock from the wires. Be careful not to pull on the wires.
You can then use our Spring Swap Key or a pair of needle nose pliers to push in this spring cap and twist to remove the cap and access the spring.
This will allow a Spring Swap or, more readily, Spring Spacers can be added to increase the tension on the spring. It’s not recommended to leave long spacers installed over an extended period of time, as it will weaken the spring over time.
Initial Set up & How-To:
1. Install Battery
2. Switch blaster into semi-auto mode.
3. Pull trigger to turn on blaster. Blaster will beep.
4. Pull trigger again to cycle the bolt and chamber a dart.
5. Pulling the trigger will fire the blaster and cycle a new dart each time.
6. In Semi-Auto mode, holding the trigger for 3 seconds will create an audible beep and swap Semi-Auto mode into 2-Round Burst Mode
7. Switching the blaster into Full-Auto mode will create an audible beep and will be able to fire automatically until the trigger is released
8. When finished operating for the day, always deprime the blaster.
Do this by switch into Semi-Auto mode, and hold the trigger for 10 seconds. The blaster will fire to deprime.
