[Silverthorn]

I am looking to buy one good Marui GBB that will last me quite a while (tired of leaky clone mags and subpar quality of other brands).

I was wondering if pretty much all Marui GBB are of very good quality (so I can just pick the one that I like) or are there any models I should stay away from? (older designs, known to have common failures, etc...).

Thanks!
