400 MOD BB Verification

[idcwby]

Just got a new Bartlein barrel and was wondering if they have a stamp on it to verify it's the new 400 MOD BB material?

It should say on the end of the barrel post a picture of it.

The "ss" stamp would indicate stainless steel if I had to take a guess, not exactly sure what they are made out of.
But also see BB in the serial number

Mine was stamped "400MODBB" on the barrel end. I thought I had a picture, but can't find it.

Both of mine had BB too

Also should have orange paint on the other end

Left two are 400 MOD BB. The unwrapped (far left) barrel has the orange paint, carbon wrapped BB does not, 30 cal (second from left).

Yes, all but the one are also left twist.

Talked with Bartlein, the BB is how they are designating the new material.

They told me BB stood for Bartlein Barrels.

Interesting.
