My mp 10 might not be a sniper rifle but don't let anything out to 300 yds get in my sites I have the Burris fulfield 11 4.5 x14 with the ballistic plex with a burris mount now Im older than some on here and at 64 300yds is a long ways for me but my first shot out to 50 yds was dead center and when I move to 125 yds same thing and when I went to 300 I was a 1/2 in off center so I love both very much
