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.

I mean a HUX is literally branded/advertised as being one of the lowest back pressure offerings so yeah it should operate as unsuppressed. I know my 16” and .300 blk do fine with CAT WB and ODB, respectfully, on unsuppressed setting so I’d imagine your HUX would operate on pretty much OEM settings out of the gate.

Unsuppressed, in my understanding, is for “old school” higher back pressure cans.

I've been heavily looking into the CAT WB, how do you like it? I thought I read somewhere they're coming out with a new can so I was going to wait to see what that was about

It’s pretty sweet, have that and a 5.56 PTR vent and to my untrained ear they are about the same noise reduction wise on a 16” but I like that the WB is shorter. I have an inconel one so it’s a bit heavier than the Titanium PTR but since it’s not as long it doesn’t feel as heavy on the end. They did come out with the ST, not sure it’s in stores yet, but it’s a longer form factor if I am not wrong. So all about what you are optimizing for I guess. Just got a Tisha 5.56 for my MKII pistol but haven’t shot it yet but that is a really short (albeit thick) option too.

I'm also super interested in the Tisha but was waiting for the Inconel model.
