Hello there, as this is my first post, i'll introduce myself a bit before I go into anything. My name is Talon, I've got a Magpul LM4, and enjoy MilSim. I've been out and about for probably 3 years now. Unfortunately, I am only 16, but I hope it won't be held against me.

On to the subject matter; In a failed attempt to lower my FPS with the spring cut method (as the DangerWerx valve was out of stock at my local store) I learned that the stock spring when heated is quite brittle. Lesson learned. My problem now is KWA is out of Part 80's and I don't have the size of the spring. I am hoping that one of you out there has an unmolested spring that can give me some rough measurements? Thanks ahead of time.

Hello! It's good to see a fellow Oregonian here :) Welcome to the forums! I don't have the dimensions on hand but I may take a look at the spring tomorrow after my game day. I think it would be in your best interests to wait for the part to come back in stock rather than trying to rig something from scratch, but by all means if you find something that works then I say 'why not?' Good luck!

I ended up getting a KWA spring from AONW. Last time I purchased one from them, the bag said "Rocket Valve Spring" and was supposedly the MP7 spring, but this time it was labeled "KWA LM4 Part 80" so hopefully this will just return her to stock internal condition (at least until I decide to take on a hopup/barrel upgrade.)

Now I just need to find a Chrono. :wacko:
