I purchased the BULLDOG Extreme Tactical 35" case from Optics Planet for my M&P 15-22 a couple yrs. back for $26 and Love It. Four outside mag pouches plus one lg. zippered pocket for incidentals. It also states that it floats! I also purchased the same case for my recent AR build, both cases have an adjustable shoulder sling. IMHO both cases are extremely well constructed and should last quite awhile. Side note: Haven't subjected either case to the float test yet!
