4x O-Ring HEAT CORE | Milsig Valken M17 | FSC | FSC XP

I have two M17s
A CQC and a CQC A2. The older one was leaking a bit, this O-Ring solved the problem. I find these O Rings easier to put in. I even think it gives some extra power
Meine ältere CQC hat manchmal durch den Bolt geleaked. Der Tausch war easy, leichter als die schwarzen von Valken.
Der Service wie immer Top Notch. Besser geht nicht!

Fast delivery and quality item. Always satisfied

Very difficult to find these anywhere else, great price, outstanding quality rings, very fast delivery, and the usual excellent customer service from HD-24 ⭐️⭐️⭐️⭐️⭐️
