Which would benefit me more?

Okay, So I found a few TBB's an ASGI, and I can't figure put which one will produce better results. Heres the first:

It's a 6.03, but made by "Bravo", of which I've never heard of.
The second is made by Classic Army, a much more known and reliable brand, but is only a 6.04:

Which would benefit my Thompson's accuracy more? I'm guessing the first, but then there's the quality contest...which I'm guessing CA would win. The CA is also $18 cheaper.

And then I'll just throw this one in, I don't know anything about this one.

I would suggest just going for the Bravo Steel one because if you get a lemon then send it in to ASGI and get a new one and if it happens again ask for your money back....if they do that

I know Bravo. They make an AEG RDW and some radio headsets, plus a few internals. From what I've seen, they aren't bad.

A better option, although more expensive, would be Prometheus. They produce the highest quality TBBs ever.

Okay, yeah I was leaning towards he Bravo one.
@ SnoSnipe, I looked, they don't carry any for the Thompson :p

Aah, probably not. I tried Bravo would be the better way out of your choices.
