Hi!, i wanna know which blowback housing is more durable for my glock 17, mine glock has the zero hammer design and i really don't know if that design can wear or damage the bbu in the rear part, (that gap where the hammer rest) i search for some BBU upgrades and i found this brands: guarder, AIP, RTS, which one could be better?

In 10 years of playing airsoft, including 5 of being an airsoft mechanic, I've never, ever seen a stock BBU fail.

So if you're planning on changing it for durability... just don't. There's no point on doing that, as the stock one will last forever.

Aftermarket BBUs are meant either to provide slightly faster cycling at the expense of lighter recoil (light weight BBUs such as the three you linked to) or to increase recoil by having a wider nozzle and seal, heavier weight and other means, such as Volante's

Oh! Thanks!!!! That's good to know!! I was really worried about that

Btw, you'r knowledge on glocks are good i guess, mine is close to zero xD, so could you tel me if the zero hammer is better than the bearing wheel hammer? I'm asking you becouse my glock wasn't cycle very well, in fact, it was getting stuck in some point, But after i sanded a little and polish that wheel zero part the cycling now is more smooth, like zero resistence
