LL4D Valken M17 - HD24 kit vs factory bolt spring 550psi output

[@runerebel8441]

Nice test Sean. Impressive numbers from just 550 PSI 😃

[@lesslethalfordummies]

Its definitely in the ball park🙂

[@THELESSLETHALSPOT]

Wow nice power at that low pressure. Interesting test as always 👍

[@lesslethalfordummies]

Thank you. Works darn well.

Factory bolt spring works fine at lower pressures , especially since you did the sear and trigger springs.

[@lesslethalfordummies]

Sure does.

what marker is that? Im on Valken's website and the M17 looks different and the mag is different...

[@lesslethalfordummies]

My base marker is an M17. The SMG magwell is a Valken accessory.
