I am the owner since long ago to a 10/22 and have been thinking to upgrade the look. I happened to search for conversions from ruger to look a like Thompson typewriter 1927. I got in contact with Woody Desmidt on Desmith Armory in WI. Yesterday it arrived and I can tell You Guys what a feeling.
It took 32 minutes to assemble and it looks great Walnut nice aluminium black coated a few bolts and bingo. I happens to have the round 50 rounds mag too. I can recomend to look at Desmidt Armory site it is all Quality.
