EM1 - Stock Valve VS No Name valve

[oldironmudder]

Well, as a few of yall know, my second EM1 came with a NON-stock valve in it & appeared to of have the lower tube bored out a little.

Also, I could not find my micrometers so I had to use my well used calipers, so they may be off just a hair.

Yeah thats the "ebay valve" Fo Sho. Definately a recomended upgrade for every em1!

if you ask me, it looks home-made...

Well it sort of is....basically when vapor works stopped making the vapor valve another guy started making a very similar valve for the bushmaster that is sold only on ebay. The older ones had the white cupseal like the one above and the ones sold now have the black cupseal. I own 4 of them, they are still available on ebay for 15 bucks.
