I have used the bullet sniffer on a desert tech. Works every time with suppressed .308 barrel mounted on the handguard (about 150mm behind the front of the suppressor). However with a longer suppressed 300 win mag barrel I had lots of trouble getting the thing to work. Tried everything including mounting to the suppressor and buying the useless parabolic adapter. Finally ended up extending a picattiny rail out past the end of the handguard at 0130 oclock postion to sit the BS 150mm behind the front of the suppressor. Seemed to work ok in this position. It had so much trouble picking up any shots from various .22 LR's that it was useless for that. The app is definately a bit basic and not intuitive. The instructions refer to settings that arent available in the app.
