Lage variable buffer length?

[Hey]

I want to speed up my new 31c. Wanting 800rpm or a little more.

I can spend $20 + shipping or 3D print one for $.40

I can replicate the Lage VBS so far as fitting into the upper with provisions for the recoil and ejector rods but don’t know how tall a VBS2 is.

Worst case I’d have to print several different heights and try them all out. I’d rather just print once and be done.

Anyone know the length measurement?

If you are referring to thickness, each VBS is 3/8” thick. So a VBS2 being 2 buffers, 3/4” thick total. If you have the capability, I would make a few 3/8” thick and experiment until you find your desired ROF.

 

[Hey]

Excellent. That’s what I need to know.

Much appreciated.

 

[Hey]

My USMG speed cube won’t fit my Lage upper.

Based on 3/8” for each vbs I modeled mine as a 2 & 3vbs knowing I’d add a rubber buffer in front which is similar to a vbs by itself.

Leaving Lage’s stack alone, I’ll probably settle on a 2 vbs and the buffer making it a 3 vbs in effect at around 850~925rpm

Printed 100% solid. They fit perfect. Need to go shooting.

I like it. Care to share the design? I'd like to print some

 

[Hey]

I’m bypassing Lage by making my own from scratch. Free country.

Distributing it, to me, is against boundaries.

You can always make your own using data gleaned from this thread.

That’s pretty cool. Please run 1k rounds on em and let us know how they hold up! I’d prefer a buffer you could push with a threaded bolt in the stock... so you could easily adjust your ROF on the fly, in the field.
