ABOUT OPTIONS
OPTION #1: Trigger board
Please select first your replica platform you want to use with SERAPH: V2 (M4), V3 (AK) or universal Plugboard.
 
OPTION #2: Wire harness length:
20cm: if you want to put your FCU in your grip, or put your FCU in your AK handguard,
30cm: for V3 (AK) and V2 (M4) with short/collapsible stocks,
40cm: for V2 (M4) with standard buffer stock length or full-stock (like M16).
 
OPTION #3: Semi-only:
Need a semi-only version due to your state laws or your field restrictions? Please select 'Yes' under the semi-only option. The FCU of SERAPH will be identical but you will not be able to choose any other firing mode than 'SEMI' on the programming display. Please note that this option is not reversible!
 
OPTION #4: Tubing:
Hard tubing/nylon (PA): this is the best option for most conversions, as nylon is durable and can not be pinched accidentally.
Soft tubing/polyurethane (PU): in some replicas/gearboxes you don't have much space to bend the air line. In this case, polyurethane tubing is better, it has a lower minium bend radius than nylon.
 
OPTION #5: Tappet plate:
If you need a special tappet plate for specific gearbox, please choose the 'Custom' option. You need to send us the dimensions of the tappet plate you need! Send us an email, fill the contact form or a private message on social medias with your order number and the dimensions. Pictures appreciated. Please note that we are not responsible of any troubles caused by a custom tappet plate.
Please note that SERAPH can be shipped without any tappet plate. You can make your own tappet plate, to be compatible with your replica. You will receive full support (3D files, technical advice) to make your own with simple manufacturing tooling or a 3D printer. In that case, SCALAR can not guarantee the proper operation of your replica!
 
 
NOTES

Please note that SERAPH is shipped without cylinder head or nozzle by default!
Please note that if you order SERAPH without a trigger board or an universal plugboard, we don't guarantee the engine running. If you encounter any issue about electronics, you are responsible.
