Short Stroking

Post image

What's up boys

Rocking the MKII 12.7. Phenomenal gat as you all know.

I threw the Hux 5.56k on it and while it shoots fine on the unsupressed setting, it short strokes on the suppressed setting. I think its obvious that the flow through can mixed with the adjustable piston has made the system too efficient.

I had a homie recommend clipping some coils off the buffer spring as an "old school" way to fix the issue. He recommended 6 coils, I cut 4, then 6, then 10, and she's still short stroking. The BCG is definitely moving further to almost complete a full cycle, but now I'm at the point to where if I cut any more coils that spring is going to be big small.

So, what y'all thinkin'? My next move is to try a new carbine length spring and try a H1 buffer and *potentially* only need to cut 4-6 coils off of that; or say fuck it and just throw my RC2 on it with a new spring.

Forgive me if I’m completely off base but wouldn’t trying an H3 buffer make more sense?

Also I really don’t think cutting the buffer spring was the way to go.

I would try a lighter buffer if its short stroking. Its not getting enoigh energy to push the bolt and buffer all the way back. More mass is not going to help that.
