Telescopic tube spring engineered for competition shotguns.
The spring is designed to fit most available telescopic tubes. The geometry of the spring will reduce tube sticking and maximise the telescopic capacity.
Depending on the original setup, total capacity increase up to 5% can be achieved with optimal spring combination. What this means is that you could be able to fit that one extra shell without sacrificing reliability. Or use longer springs for added reliability for your magazine system. This spring will allow you to tune your telescopic system for function and capacity. And also be a high quality general spare spring for all systems.
Recommendation is to use a spring setup, that will start the telescopic expansion when the inner tube is 100% full (typically 10 shells). Using this recommendation will keep the telescopic system from expanding unnecessarily, keep it short and keep it clean as possible. Minimum recommended setup is when telescopic expansion starts at 90% full (typically 9 shells).
Note: the spring is most likely tighter fit during assembly than the orginal spring. This is okay, and it is designed that way. The diameter and clearance of the spring increases when compressed.
Specifications:
