I have owned 2 different M&P 15-22s. They are great rifles. I bought the standard model, brand new, from Grouse River back when the S&W 25 round mags were legal. The restricted status did not bother me, because, at the time, I did all my shooting at a range.I then sold it and bought a lightly used MOE version. I loved that one too until I got a letter from the RCMP telling me I was limited to 10 round mags. That took the fun out of it for me. I sold the S&W and got a CMMG .22 conversion bolt with BD 25 round mags for my AR. Then I also got an SR-22 as I started to do more shooting away from the range. I like the SR-22, it is very reliable and great fun, but I really miss being able the push out one pin and field strip the rifle in 3 seconds like you can with an M&P or AR. The SR is definitely more work to field strip and clean.
I noticed 2 different 15-22s for sale on the EE in the last few days.
