I have it on my USC. Fit / finish is great. Works flawlessly after switching to roll pins. (they send them to you free). I would like an  ambi mag release though, which doesn't seem like it would be hard to do. . . . Anyway, loosing the botl hold open to get the ability to use 30 rnds $10 mags is a good deal I think.

Edited to add: Yes, I installed it myself. It wasn't too hard.

Been thinking of this conversion myself,  can you put the stock lower back on and still have the bolt hold open, and function like the stock gun? Do you have to modify the upper in any way? Do you need to but it through an FFL?

Thanks in advance JBhunter

Yes, you can put the stock lower back on and it'll be right back to how it was. Bolt hold open and all. You DO have to modify the upper. You need to shave between 1/16 and 1/8 of an inch off the inside of the hole the mag goes through, or else the mag won't go in. It is minor, easy, and doesn't effect the gun any. You do not need to go through an FFL, as the UPPER on a USC is the firearm. The lower is nothing.
