Silverback Airsoft APS 13mm Main Spring for SRS & TAC-41
This spring is following the “APS 13 mm standard” (for 9 mm outside diameter spring guide). It will fit any rifle compatible with this standard, including all SRS (except push mechanism) and all TAC-41. While being compressed at 99 mm in length, it delivers 100 Newton (+/- 5%, around 9 Kg of force). This spring received a black electrophoresis coating, and a laser marking to quickly identify the spring.

Ordered the 150N spring as the 120N was sold out. The 150N spring ended up being perfect for my Tac-41A and it's shorter inner barrel length. I combined the spring with Silverback's V.M.P. system and have it tuned up to chrono right around 2.8j. Chrono readings with 0.45g HPA brand BBs = 2.78j with hop set below #3, and just under 3j with hop set between #4 - #7. Everything else is as it came from Silverback (60* silicon flat hop bucking and 330x6.05mm inner barrel). I'm going to run this configuration for a bit before I swap the bucking with the 70* bucking and a precision 6.01mm EdGI or Lambda barrel. As I'll need to re-tune the piston weight and or spring strength.
