Sigelei has made a few mechanical mods over the last few months, but this we call #8 is the best of the bunch. This features the flat top so rebuildables fit flush. Tony (in the 2nd to last picture) said it was extremely heavy and built very well. He also deminstrated how the threads vanish when the mod is put together. Something rare when it comes to China mods.
For the price you cant go wrong. A STEAL at $33.99. I have already bought 2.
This is a pre-order deal. They will ship mid to end of April.
