I have a M11/22 and Max-11/22 (old style).
Like them both, but they have a different personality. A lot of it depends on what stock you will be running, and what C/F upper most. The sight height is quite different for the OEM style upper and the Lage offerings.
My M11/22 kit is in a dedicated upper, threaded liner as mentioned in above post. It runs great even with CCI SV. I think locking the barrel liner in place makes it more reliable. It just chugs along nice & quiet with CCI SV. Put Stingers in it and the ROF seems to double (as does the noise).
