The kit I bought from Sarco had everything I needed, but the hammer was questionable. Prof. Hale gave me one (and some other parts) from his personal stash; it went in perfectly and worked perfectly- having seen both hammers, I now know mine had missed a manufacturing step, hence it’s failure to operate properly.

Aside from that, the lower went together with remarkable ease, and yes, you could easily put it together on a TV tray. Mine will most likely remain an M4gery it’s whole life, though I kinda like the look of that Magpul UBR stock. I’ve always been a sucker for secret compartments, and having a place t store a wound up pullthrough could be of some utility. I see they make a plug so you can use the pistol grip similarly, so I may go that route instead of the $250 worth of magpul plastic.

I have approached this whole subject through the eyes of a mechaincal geek, and all the things I’ve discussed have related to how the firearm is designed and how it works and how it is supposed to work. Anyone who has ever worked on one, who is not a fool, can see the really marvelous thought that has gone into it’s design, and the brilliance that is in the basic manufacturing process.

Having never carried one in battle, and having only put a very few rounds through mine (though plenty through other’s) I can not make any claims as to it’s effectiveness as a battle rifle, and I won’t, and I won’t even have that discussion.

Having shot them in their many forms, I can say, it’s a hoot to shoot, and I look very much forward to shooting mine more. The time may come that I do another, after all the pieces are inexpensive enough. Putting my hands on a really tight heavy barrel and a freefloatinhg handguard? Could be awhole lot of fun. But then I don’t have too many places I can shoot that far anyway.

All in all, from a pure engineering standpoint, I am impressed. And I don’t impress easily.
