AA Chamber - $57.50Masada arm won't fit.
I'd buy whatever is cheaper after shipping, and if you get the AA, look at making the SS-nub in my signature.
I'm using stock SSG10 (comes with Autobot 60 degree if I'm not wrong), but I already bought a few 2021 Autobot 70 degrees.I don't really care much about TDCs if the accuracy is the same, but some people think they are the best thing ever. If you think you really need a TDC, I guess TTI it is then.
What are you planning for a bucking?
What bucking are you using?Each to their own. I would go for the TTI hands down.
Also, one other thing, I do seem to be getting higher fps with the TTI. This may be because the air seal is better, or the bucking matched the chamber better. But in reality, I do not know but it is getting higher fps. (20-30fps)
The design is very, very, very similar to AA but it has extra better features.
I could if I were guaranteed 20-30fps over my current setup.......as you well know the increase might not be anywhere near that high given the vagaries of airsoft mechanics. As it stands I'm happy as is - there's no need for me to get another hop chamber to chase numbers - not my bag baby!You could just use a weaker spring, and then have a better pull and quieter gun
