I received the kit today. The package includes everything you see in the pic below.
First there's the slide itself. It looks very well made. It looks identical to the stock ASB slide from the gun. Take them apart and put them side by side, and you would't be able to tell any difference. Trademarks are deep and well engraved. No half-assed shallow engraving here. It really is identical to the TM ABS part in every way except material. The slide has none of the internals or sights. You have to transfer everything from your gun onto this one.
Next is the metal outer barrel. Again, looks just like the TM part, only metal. Not sure what else to say about this. I don't know enough about this stuff to be able to accurately gauge quality, but it seems decent enough.
In the bag comes the enhanced recoil spring, which doesn't feel significantly stiffer than the stock spring. And there's another small plastic part the I THINK is a cylinder head or something. I'm not really sure, exactly what it is, but I know there's a similar part in the gas block on the stock gun. By its shape and size, I assume it's a cylinder head. Please correct me if I'm wrong.
I won't be installing this right away for a couple of reasons. First, I'm expecting a bunch of other parts from eHobby Asia to upgrade this gun. That includes a Nineball 6.03 tightbore barrel, King Arms airseal chamber, Guarder steel spring guide, and Guarder 150% recoil and hammer springs. Secondly, I sent my old slide back to Hellfire today and he'll be sending me a brand new one when he ships me my RS Type 56 later today.
I will let everyone know how it works out when I get it upgraded.
