Great Spring! Fires like a cannon

powerful spring

it is very powerful and now my kronos shoots harder than all my other rival blasters. I do not recommend this for a child because it requires a bit more force to prime.

Essential

Easy to install; insane boost in performance compared to how it fires out of the box. Prime is just right; not light, but not too hard. Anything stronger, would ultimately make this a one shot/last resort sidearm. Thanks Out of Darts; quality mod parts at a FAIR price tag. Great service too!

Excellent

Great size spring for Kronos and Takedown. Both hit consistently between 125 to 135 fps with padded plunger tube, Teflon taped O-ring and good amount of lube.
Still very accurate.

Great but heavy to prime

This is a great spring and it buffs the kronos, but beware when buying this that it makes the kronos hard to prime. So don't get this for a someone young. I bought this and just ignored all the reviews that said it made it hard to prime because I just thought "How hard can it be?" pretty difficult. Great spring for upgrading kronos just don't buy for anyone who isn't that strong.
