The Smith and Wesson 15-22 is another great AR15 clone chambered in 22LR. This is a very light , accurate rifle at 50 yards. It’s okay at a hundred yards on a calm day. I have a Sig inexpensive red/ green dot scope installed on the rifle that really makes it a pleasure to shoot. My previous review on the HK chambered in 22LR manufactured by Walther is still my favorite of the two. The S&W is lighter, less expensive, and also very reliable. It is a fun day when you can go through five hundred rounds of 22LR for under fifty dollars. have posted You Tube videos that are very entertaining.
