RUGER 10/22 conversion views

I recently felt I would upgrade my standard Ruger frame for this little beauty, an Archangel Nomad folding stock conversion, for plinking the rabbit problems around me. I have to say it took slightly longer to put together than the manufacturers expressed on their instructions, and still not fully sure about the magazine, but people are raving about it, it seems in the States. Put 100 rounds down range this morning with only a couple of feeding issues caused by the spring retainer on the mag.
Has anybody else tried this kit?:
